2021-07-31T17:54:13+10:00

Artificial Intelligence has seen a boom in all types of industries and it is something we can find at both our homes and offices including industries like medicine. Some of these we cannot imagine living without. AI has saved lives many times in the absence of a human presence. SMS diallers are one such category of technology that can be very useful in critical situations of emergency.

SMS diallers are similar to voice alarm diallers, in the sense that SMS diallers raise an alarm as well. SMS diallers are widely more popular for raising a SMS alerts rather than a call, as observed in case of voice alarm diallers. Two common ways SMS diallers can be used include:

  • Receive alarm alerts in the form of SMS in case of changes in the initial setup
  • Send SMS messages to control the equipment attached.

What is voice dialer technology?

2021-07-27T20:14:19+10:00

Voice alarm dialers are technology involving automated systems that generate calls under specific conditions. The conditions are predefined by the user and violation of which leads to the arousal of an alarm or signal. These are best suited to raise an alarm or place a call without using hands. Voice dialers avoid repetitive tasks and enhance efficiency by reducing the chance of missing a call or alarm.

Voice alarm dialers help in ringing an alarm on your cell phone or landline. When an emergency situation arises, the alarm blows and you are contacted in the registered way.

Voice dialers are fully automated systems that will not shut off until and unless a specific action is taken against the cause. Voice alarm dialers by EDAC work best with both cell phone and landline.

Uses of voice alarm dialers

  • Environmental monitoring for finding the cause of any trouble. For instance, an open window once you have left the house or just monitoring humidity in case of a manufacturing plant
  • Monitoring room temperature to keep it optimized according to your requirements
  • Water treatment emergencies including leakage
  • Fire alarms or any smoke that has occurred
  • Prevents interaction with third-party, by eliminating the need for a server in between to send an alarm to your device

All these facilities are based on a predictive dialing system instilled in the device that lets it to call out on specific numbers in case of an emergency or defined situations.

Types of voice dialers by EDAC

Various types of voice alarm dialers are available to choose from. Depending on the appliances you want to connect it to, the use ‘personal or industrial’ and the number of alarms you need, you can choose from the following. The features of each have been described in short:

Whether you wish to monitor a temperate setting, humidity in the room or major events like fire, EDAC voice alarm dialers are best suited. All the installation and setting up are quick and one-time in the beginning. Each product has a security pin instilled to prevent any theft or privacy invasion.  EDAC has been providing flexible and quality auto dialers for almost 2 decades now. The dialers function by the use of sensory sentinels attached inside them to perceive the changes in the surrounding.

They also have the power to convert text inputs into speech. All they need is a working electrical supply and they will use their existing memory and space to work on the task. Voice alarm dialers can be very compact and heavy, depending on the type of usage they are designed for. Some of the dialers like Matrix GFX11 3G/4G Gateway. By EDAC have 3G 850/2100, 4G 700/850/1800/2100/2600 and 3G and VoLTE (Voice over 4G) support

In conclusion, when an alarm occurs, EDAC’s voice alarm dialers dial the callout numbers listed earlier and dictate the situation in pre-recorded and crystal clear voice. The user is required to take action using a set of dial keys as set up. Without which, the dialer will continue to send out signals or alarms until the user responds with an action. Voice alarm dialers are best suited to avoid accidents from happening.

What is SCADA? A Complete History, Evolution and Function of SCADA

2021-07-28T23:06:32+10:00

Supervisory control and data acquisition (SCADA) is a system of software and hardware elements that allows industrial organizations to:

  • Control industrial processes locally or at remote locations
  • Monitor, gather, and process real-time data
  • Directly interact with devices such as sensors, valves, pumps, motors, and more through human-machine interface (HMI) software
  • Record events into a log file

SCADA systems are crucial for industrial organizations since they help to maintain efficiency, process data for smarter decisions, and communicate system issues to help mitigate downtime.

The basic SCADA architecture begins with programmable logic controllers (PLCs) or remote terminal units (RTUs). PLCs and RTUs are microcomputers that communicate with an array of objects such as factory machines, HMIs, sensors, and end devices, and then route the information from those objects to computers with SCADA software. The SCADA software processes, distributes, and displays the data, helping operators and other employees analyze the data and make important decisions.

For example, the SCADA system quickly notifies an operator that a batch of product is showing a high incidence of errors. The operator pauses the operation and views the SCADA system data via an HMI to determine the cause of the issue. The operator reviews the data and discovers that Machine 4 was malfunctioning. The SCADA system’s ability to notify the operator of an issue helps him to resolve it and prevent further loss of product.

Who Uses SCADA?

SCADA systems are used by industrial organizations and companies in the public and private sectors to control and maintain efficiency, distribute data for smarter decisions, and communicate system issues to help mitigate downtime. SCADA systems work well in many different types of enterprises because they can range from simple configurations to large, complex installations. SCADA systems are the backbone of many modern industries, including:

  • Energy
  • Food and beverage
  • Manufacturing
  • Oil and gas
  • Power
  • Recycling
  • Transportation
  • Water and waste water
  • And many more

Virtually anywhere you look in today’s world, there is some type of SCADA system running behind the scenes: maintaining the refrigeration systems at the local supermarket, ensuring production and safety at a refinery, achieving quality standards at a waste water treatment plant, or even tracking your energy use at home, to give a few examples.

Effective SCADA systems can result in significant savings of time and money. Numerous case studies have been published highlighting the benefits and savings of using a modern SCADA software solution such as Ignition.

How Can SCADA Help You?

Applying a SCADA system in your facility can help decrease production waste and boost overall efficiency by providing useful production insights to operators and management. The information derived from a SCADA system can facilitate data-driven decisions and lead to increased output, reduced costs, and greater control of your processes.

Another benefit of SCADA is instant notification and automated response to system alarms. With the immediate knowledge of issues in the production process, operators and back-up systems are able to respond quicker to reduce equipment downtime and wasted product.

At Process Solutions, we have a team of certified SCADA engineers that work with our clients to develop custom systems to match any manufacturing environment. For more information about SCADA software, or to request a demonstration, please contact us below to discuss your requirements.

Functions

The core functions of SCADA include:

  • System monitoring
  • Automated control of industrial processes and machines
  • Data collection and analysis
  • Event and Alarm Notifications
  • Reporting

To perform these functions, SCADA integrates with sensors and other measuring devices, which can be in either digital or analog form, to collect data. The collected data is then sent to  remote terminal unit (RTU) or programmable logic controller (PLC) to be translated to usable information. Finally, the information is relayed to a human machine interface (HMI) or other types of displays for operators to analyze and interact with.

SCADA systems also enable the ability to automate the control of industrial processes and machines that would otherwise be too complex for manual human control. Through the use of sensors and measuring devices, SCADA systems can detect abnormal parameters or alarms and automatically respond with a programmed control function. For example if an alarm occurred signaling to much pressure in a line, the SCADA system would trigger a programmed response to open a pressure relief valve to return pressure levels to a normal amount.

The Birth of SCADA

DOE’s Office of Scientific and Technical Information (OSTI), Office of Science [Public domain], via Wikimedia Commons

To understand the origins of SCADA, we must understand the problems industrial organizations are trying to solve. Before the concept of SCADA was introduced in the mid-20th century, many manufacturing floors, industrial plants, and remote sites relied on personnel to manually control and monitor equipment via push buttons and analog dials.

As industrial floors and remotes site began to scale out in size, solutions were needed to control equipment over long distances. Industrial organizations started to utilize relays and timers to provide some level of supervisory control without having to send people to remote locations to interact with each device.

While relays and timers solved many problems by providing limited automation functionality, more issues began to arise as organizations continued to scale out. Relays and timers were difficult to reconfigure, fault-find and the control panels took up racks upon racks of space. A more efficient and fully automated system of control and monitoring was needed.

In the early 1950s, computers were first developed and used for industrial control purposes. Supervisory control began to become popular among the major utilities, oil and gas pipelines, and other industrial markets at that time. In the 1960s, telemetry was established for monitoring, which allowed for automated communications to transmit measurements and other data from remotes sites to monitoring equipment. The term “SCADA” was coined in the early 1970s, and the rise of microprocessors and PLCs during that decade increased enterprises’ ability to monitor and control automated processes more than ever before.

The Evolution of SCADA

The first iteration of SCADA started off with mainframe computers. Networks as we know them today were not available and each SCADA system stood on its own. These systems were what would now be referred to as monolithic SCADA systems.

In the 80s and 90s, SCADA continued to evolve thanks to smaller computer systems, Local Area Networking (LAN) technology, and PC-based HMI software. SCADA systems soon were able to be connected to other similar systems. Many of the LAN protocols used in these systems were proprietary, which gave vendors control of how to optimize data transfer. Unfortunately, these systems were incapable of communicating with systems from other vendors. These systems were called distributed SCADA systems.

In the 1990s and early 2000s, building upon the distributed system model, SCADA adopted an incremental change by embracing an open system architecture and communications protocols that were not vendor-specific. This iteration of SCADA, called a networked SCADA system, took advantage of communications technologies such as Ethernet. Networked SCADA systems allowed systems from other vendors to communicate with each other, alleviating the limitations imposed by older SCADA systems, and allowed organizations to connect more devices to the network.

While SCADA systems have undergone substantial evolutionary changes, many industrial organizations continued to struggle with industrial data access from the enterprise level. By the late 1990s to the early 2000s, a technological boom occurred and personal computing and IT technologies accelerated in development. Structured query language (SQL) databases became the standard for IT databases but were not adopted by SCADA developers. This resulted in a rift between the fields of controls and IT, and SCADA technology became antiquated over time.

Traditional SCADA systems still use proprietary technology to handle data. Whether it is a data historian, a data connector, or other means of data transfer, the solution is messy and incredibly expensive. Modern SCADA systems aim to solve this problem by leveraging the best of controls and IT technology.

Modern SCADA Systems

Modern SCADA systems allow real-time data from the plant floor to be accessed from anywhere in the world. This access to real-time information allows governments, businesses, and individuals to make data-driven decisions about how to improve their processes. Without SCADA software, it would be extremely difficult if not impossible to gather sufficient data for consistently well-informed decisions.

Also, most modern SCADA designer applications have rapid application development (RAD) capabilities that allow users to design applications relatively easily, even if they don’t have extensive knowledge of software development.

The introduction of modern IT standards and practices such as SQL and web-based applications into SCADA software has greatly improved the efficiency, security, productivity, and reliability of SCADA systems.

SCADA software that utilizes the power of SQL databases provides huge advantages over antiquated SCADA software. One big advantage of using SQL databases with a SCADA system is that it makes it easier to integrate into existing MES and ERP systems, allowing data to flow seamlessly through an entire organization.

Historical data from a SCADA system can also be logged in a SQL database, which allows for easier data analysis through data trending.

ScadaPhone was designed to allow SCADA systems to have a highly configurable way of sending notifications and alarms directly form SCADA via Voice call, SMS and , Email.

Rio Tinto: Replace natural gas with hydrogen in alumina refining

2021-07-25T03:48:08+10:00

The Australian Renewable Energy Agency (ARENA) will provide up to $579,786 in funding to Rio Tinto to support a feasibility study, investigating the potential to partially decarbonise its alumina refining operations using renewable hydrogen.

Conventional alumina refining combusts natural gas to achieve the high temperatures required in the calcination process. Rio Tinto aims to investigate the technical implications of displacing natural gas with renewable hydrogen at its Yarwun alumina refinery in Gladstone, Queensland. The study would inform the viability of a potential demonstration project to validate the findings.

The $1.2 million study, funded equally by ARENA and Rio Tinto, will comprise two distinct work packages:

Simulating the calcination process using a lab scale reactor at Rio Tinto’s Bundoora Technical Development Centre in Melbourne, Victoria.
Preliminary engineering and design study conducted at Rio Tinto Yarwun to understand the construction and operational requirements of a potential demonstration project at the refinery.
The study will improve understanding of and the potential for renewable hydrogen to be used in the alumina refining process. It will also inform the scope of development works required to implement hydrogen fuelled calcination technology at an existing alumina refinery.

As the world’s largest producer of bauxite and largest exporter of alumina, Australia accounts for 15 per cent of global alumina refining capacity. The process is energy intensive, using high pressure steam to produce heat and process bauxite into alumina. Then alumina can be converted to aluminium through smelting.

In its strategy to support industry in reducing emissions, ARENA has targeted the alumina sector as key to achieving this. Alumina refining accounted for over 14M tonnes of carbon dioxide in Australia in 2019, representing around 24 per cent of the country’s scope 1 manufacturing emissions.

The Australian government’s first Low Emissions Technology Statement also highlights the importance of developing a low emissions steel and aluminium industry, to help reduce emissions and stimulate economic activity. Innovation in metals refining can improve the competitiveness and emissions intensity of Australia’s steel and aluminium production.

Last month, ARENA announced $11.3M funding for Alcoa to investigate and deploy an alternative technology using recycled steam for process heat, powered by renewable energy.

Rio Tinto’s study will explore potential for hydrogen to reduce emissions across the aluminium supply chain and complement Alcoa’s project, ARENA CEO Darren Miller said.

“If we can replace fossil fuels with clean hydrogen in the refining process for alumina, this will reduce emissions in the energy and emissions intensive refining stage of the aluminium supply chain,” Miller said.

“Exploring these new clean energy technologies and methods is a crucial step towards producing green aluminium. This study will investigate a potential technology that can contribute to the decarbonisation of the Australian alumina industry.

“If successful, the technical and commercial lessons from Rio Tinto’s study could lead to the implementation of hydrogen calcination technology, not only in Australia, but also internationally,” he said.

Rio Tinto accounts for about a third of Australia’s total alumina production capacity. Its aim is to reach net zero emissions across operations by 2050. Company-wide, it is targeting a 15 per cent reduction in absolute emissions and a 30 per cent reduction in its emissions intensity by 2030, from a 2018 baseline.

“We see the ARENA and Rio Tinto-funded study as a step towards reducing refinery emissions and one that has the potential to play an important part in Rio Tinto’s commitment to decarbonisation,” Rio Tinto Aluminium Pacific Operations acting managing director Daniel van der Westhuizen said.

“We’re investing in work that needs to be done, not only to decarbonise one of our sites, but also to help provide a lower-emissions pathway for Rio Tinto and the global aluminium industry.

“We recognise we are on a long road towards reducing emissions across our operations and there is clearly more work to be done. But projects such as this are an important part of helping us get there,” he said.

Antenna Basics

2019-08-30T21:02:26+10:00

How Antennas Work

Antennas are effectively transducers converting the electrical energy into electromagnetic waveforms between sending and receiving devices.

While there are variations such as folded antennas, the basis of antenna design is a core conductor (referred to as a radiator) of ½ electrical wavelength in size. AC voltage and current is then applied to the conductor to create a resonant circuit to a given frequency (ie capacitive and inductive reactance equaling zero). At frequency resonance, only pure resistance is left, a function of Ohmic and radiation resistance.
As Ohmic resistance creates heat energy losses, efficient antenna design optimizes radiation resistance in generating the waveform. The resultant waveform is a composite of a magnetic field and electrical field which are 90 degrees out of phase. Of practical importance in communications, antenna polarization reflects the direction of the electric field relative to the Earth’s surface and the antenna’s physical construction/ orientation. Antenna polarization within a system should be the same for reliable communications.

Illustrated above, polarization is the orientation of the antenna, the electric field and Earth’s surface. A mismatch in polarization introduces severe communication losses into a system.
As antennas are designed and manufactured to a given frequency or to operate within a band of frequencies, matching antenna specifications to the frequency of the system is pivotal to reliable communications. While a mismatch of antenna to system frequency may still allow some absorption of the waveform, its relative efficiency and reliability are greatly reduced. Different types of antenna technology are discussed subsequently.

Isotropic Antennas

The basis of antenna design and gain is the theoretical isotropic antenna which radiates in a three dimensional spherical pattern (see below).

The isotropic antenna is a theoretical construct only as the radiation pattern becomes distorted in certain directions in physically realisable antennas.

Image above depicts an isotropic antenna radiating a three dimensional spherical pattern.

Read more

Dipole Antennas and Polarization

Dipole antennas are manufactured with an active conductor (referred to as a radiator) equal to ½ the wavelength of the design frequency. The effect of the 1/2 wavelength design is to distort the RF power envelope direction to the horizontal plane (ie there is more power radiated to the sides than up and down).

The directed radial envelope is commonly referred to as the antenna’s gain which compensates for losses created in the coaxial cable and connectors. Antenna gain may be expressed as either dBi or dBd and can be confusing as manufacturers do not always specify which metric is referenced.
When antenna gains are expressed as a comparison to the transmitter (TX) power/ isotropic antenna, they are referenced in dBi. Conversely, if the antenna gain is referencing a dipole antenna, it is referenced to dBd. The directed gain of a dipole antenna + 2.14 dB indicates there is an increased horizontal gain of 2.14dB (with consequent vertical loss), relative to power from the transmitter (TX power)/ isotropic antenna. Establishing the reference point as either dBi or dBd is of practical importance in system design given the increased reach of the dipole antenna relative to a reference isotropic antenna.
Irrespective of reference point, for effective communications reach, a dipole should be mounted vertically at it has a positive gain in the horizontal plane given the orientation of the electric field relative to the Earth’s surface.

As illustrated, the dipole antenna distorts the directed energy in the horizontal plane with consequent loss in the vertical plane (ie up and down).

As indicated, government regulations mandate the amount of radio power emitted from a wireless device in order to manage the spectrum. These bodies will reference the maximum transmitter power and overall gain relative to an isotropic antenna or gain relative to a dipole antenna.
Equivalent/ effective isotropically radiated power (EIRP) is a measure of overall gain (including coaxial and connector losses) referencing an isotropic antenna of equivalent signal strength, measured in dBi. As the isotropic antenna is a theoretical construct, a more practical measure is the effective radiated power or ERP. ERP also references overall gain (including coaxial cable and connector losses) relative to a half-wave dipole antenna and is measured in dB.
More generally gain may be expressed as:

Read more

Collinear Antennas and Polarization
By design, the horizontal radiation pattern can be extended further by connecting multiple dipole elements together.

These antennas are known as collinears and are normally manufactured with gains of 5dB, 8dB or 10dB. Like dipoles, collinear antennas are vertically polarized for effective communications.

As illustrated, the collinear antenna further distorts the directed energy in the horizontal plane improving reliable communications distances.
Dipole and collinear antennas are termed omnidirectional as they transmit in an approximate 360 degree horizontal radius. Typical uses for these types of antenna are where outlying units are scattered around a sizable arc radius and/or in inter-plant applications where reflected signals over short distances are received at various arcs to the original.

Read more

Yagi Antennas and Polarization

The forward direction of the radiated waveform can be further increased by adding reflector elements which act to focus the waveform in a forward direction (with the consequence that the back and side lobes are reduced).

These types of antenna are referred to as Yagi antennas with the addition of more reflector elements adding forward gain but a more focused narrower beam width. These antennas are often used for long line of sight radio point to point applications and intra-plant applications.

Yagi antennas focus the waveform in a forward direction reducing lobes at the rear and sides of the antenna; typically used over longer distances in a point to point fashion.

With increased forward gain Yagi antennas beam width becomes narrower.
Yagi’s are mounted with the central beam horizontal and the orthogonal reflector elements either vertical or horizontal (relative to the Earth’s surface). If the elements are vertical, the Yagi is transmitting with vertical polarization; if the elements are horizontal, the polarity is horizontal.

Polarization of a Yagi antenna will impact on the orientation of the propagated waveform.

Read more

Other Antenna Types

The previous antennas centered on distance communications but not all wireless communications involve longer communications links (eg replacement of slip-rings on a rotating kiln).

Applications over shorter distances may necessitate the use of a ¼ wave whip antenna. These antennas are simply a ¼ wavelength conductor and can be mounted directly to the wireless device (typically ground-dependant antennas using the housing Earth to propagate). Another option is to have a small run of coaxial cable attached (ie ground-independent) for antenna placement flexibility. More generally ¼ wave whip antennas range from unity gain to a loss of -2dB when combined with the coaxial cable.
Another antenna option used in higher frequencies such as 2.4GHz is the parabolic antenna. Parabolic antennas add side reflectors to amplify the forward gain even further (relative to a Yagi antenna) but with extremely narrow beam-widths. For 2.4GHz devices, parabolic reflectors behind the dipole element yield extremely high gains and extremely narrow transmission beams.

From left to right, (A and B) 1/4 wave whip antennas with and without coaxial cable, (C) 2dB gain dipole, (D) 5 dB gain collinear, (E) 6 element Yagi and (F) 2.4GHz parabolic antenna.

REMOTE MONITORING AND THE NBN. KNOW WHERE YOU STAND.

2019-08-30T21:04:47+10:00

EDAC is NBN Ready

The National Broadband Network (nbn™ network) is upgrading most existing phone networks in Australia. Your Voice Dialler can continue to operate on the NBN by requesting that your NBN provider supplies either an FXS or a UNI-V port on their connection box to plug in your voice dialler (analog phone device).
One drawback of the new network connections is that they’re not guaranteed to work during a power outage as the nbn™ access network requires power at both the exchange and within the home or business to operate.
Voice alarm diallers are still the most reliable way to ensure an immediate alarm notification and
a substitute pathway such as a Cellular device can be installed prior to migrating the nbn™ network to ensure safe and reliable voice connection during a power outage.
A line selector switch can be implemented to switch between networks as necessary or the dialler can be plugged straight to the cellular interface to be used on the alternate network.

For more information please call EDAC on 03 9762 6244

Boxed options with EDAC400 and PSU13A uninterruptible power supply

We recommend voice alarm notification over SMS in case of critical alarms. Voice calls are more likely to be answered, particularly at odd hours, cannot be delayed and your voice dialler will continue to dial the pre-programmed phone number in succession until the alarm is acknowledged. For an efficient pre-assembled voice dialler monitoring system ask Edac to supply the electrical box complete with your pre-configured dialler, battery back-up power supply and optional cellular interface with an antenna to suit the reception requirement at the designated installation site.

Introduction of the new sensors with their Importance to ensure 24/7 safety of HVAC systems

2019-08-30T21:06:38+10:00

Introduction of the new sensors with their Importance to ensure 24/7 safety of HVAC systems

We all know the importance and usefulness of sensors and remote monitoring systems that can help us with proactive maintenance and prevent HVAC equipment malfunctions or failures. For many years EDAC remote monitoring systems have been helping customers by providing sensors to monitor vital environmental and operating conditions in HVAC systems.

Conditions that require continuous monitoring like, temperature, humidity, power failure, water leaks, and equipment failure are very important in environmental monitoring. With the use of an EDAC monitoring system, you can provide users the ability to monitor conditions and receive alarms via the built-in auto dialler remotely.

EDAC also supplies sensors that are used to measure airflow in ductwork, the pressure differential in ducts and rooms, and dew point. The sensors can be used with any EDAC HVAC remote monitoring device that accepts a 4-20mA of an input signal.

Duct Mount Air Flow TransmitterDuct Mount Air Flow Transmitter: To measure the rate of airflow and user alerts, this sensor is used with the EDAC system when conditions cross the threshold pre-set value. The sensor in the transmitter checks the availability of cool moving air and measures relative airflow from a 0-16 meters per second.

Differential Pressure SensorDifferential Pressure Sensor: The sensor is able to measure the air pressure in two areas and displays, if found, a difference in the readings. The sensor is widely used where a specific pressure differential maintenance is required. This sensor is used to check for the presence of a vacuum upon opening a door that could pull dust or other pollutants into the space. Differential Pressure is also used in air handlers. The sensor comes with a kit that allows measurements to be taken in ductwork or an attractive wall mount kit to measure ambient room pressure.

Dew Point SensorDew Point Sensor: To protect the system environment from atmospheric changes, we need a number of sensors to measure atmospheric conditions. Similarly, Dewpoint sensors are used to measure the temperature and humidity in the air that may condense and turn into dew. Dew point is critical in dehumidification systems that remove the moisture in environments like manufacturing plants. In refineries, this plays a crucial role as it requires dry air as moisture breeds fouling of sensors and actuators and promote rusting. The sensor comes enclosed in a Dew point weatherproof enclosure that is suitable for use in outdoor environments.

HVAC Applications:

These sensors are widely used to monitor conditions in the following systems:

  • Cooling towers
  • Air- and water-cooled chillers
  • Air Handlers
  • Refrigeration units
  • Power generators
  • Control rooms
  • Office environments
  • Data centres

An EDAC system not only monitors, it is also responsible for sending alerts when any conditions change from the normal range. With instant alarm alerts, you can take instant action before potential damage occurs. And with our monitoring systems, you can also see real-time status remotely from internet-connected devices.

Once connected, you can also collect data from all the sensors. This data logging feature is useful for keeping tabs on your systems and keeping records of compliance. Sensor readings are securely archived and readily available from anywhere via cloud-based storage. It is fast and easy to print, graph or export accurate historical records, creating an audit trail of all user data activities, edits or deletions.

Other useful sensors for HVAC applications

  • Air quality sensor
  • Humidity sensor
  • CO2 sensor
  • Carbon monoxide sensor
  • Vibration sensor
  • Smoke detector sensor
  • Water detector sensor
  • Infrared motion detector sensor
  • Temperature sensor

Wireless Temperature Sensors

2019-08-30T21:07:31+10:00

Wireless Temperature Sensors

Temperature monitoring, immediate alarm notification and secure data logging are essential tools for staff responsible for stock stored in refrigerators and freezers. Costly inventory such as food products and pharmaceuticals can be seriously compromised by storing at incorrect temperatures and lead to stock spoilage.

Edac supplies simple solutions to wirelessly monitor your fridge/freezers and is ideal for use in areas where running wires is difficult.

For added security Edac can supply wireless temperature sensors that are used in conjunction with a vial filled with glass beads that act as a buffer against temporary temperature fluctuations caused by such things as doors being opened or defrost cycles. This allows you to read accurate temperatures of the contents inside the fridge rather than the surrounding air. Sensors monitor temperature ranges from -50 to 80 degrees.

Edac’s range of wireless temperature sensors are ideal for all food and medical cold storage applications including

  • Vaccine
  • Food Manufacturing
  • Research and testing
  • Retail locations
