RT1/RT2

RT1/RT2

The RT1 direct-mount version of this transmitter includes an RTD sensor ranging from 2 to 18 inches in 1 inch increments while the RT2 multi-vendor version includes a junction box with wiring terminal board. In addition, this wireless instrument can be used with any third-party Platinum 100 Ohm RTD sensor and support 2, 3, or 4-wire type.

Equipped with a local LCD display that can be used for reading process data and for programming the device. Thus, cables and PC are no longer required for quickly setting up the device.

Description

OleumTech WT Series Wireless RTD Temperature Transmitter is a self-contained, battery-powered temperature measurement solution using RTD platinum 100 Ohm sensor and is made especially for the remote, rugged environments without access to a power line.

This device is part of the OleumTech Wireless Sensor Network.

The RT1 direct-mount version of this transmitter includes an RTD sensor ranging from 2 to 18 inches in 1 inch increments while the RT2 multi-vendor version includes a junction box with wiring terminal board. In addition, this wireless instrument can be used with any third-party Platinum 100 Ohm RTD sensor and support 2, 3, or 4-wire type.

All WT Series Wireless Transmitters are equipped with a local LCD display that can be used for reading process data and for programming the device. Thus, cables and PC are no longer required for quickly setting up the device.

The Wireless RTD Temperature Transmitter is intrinsically safe (certified for use in Class I, Division 1 C1D1 Wireless (Zone 0) hazardous areas). It can be operated in a hazardous environment with or without the enclosure without the risk or fear of causing an explosion. This wireless end node transmits collected data to a Wireless Gateway that supports Modbus. The transmitter uses license-free, secure data transmission with a range of up to 7500 ft. Range (2.3 Km).
