Description

OleumTech WT Series Wireless High Level Switch Transmitter – Side Mount is a self-contained, battery-powered spill/overflow prevention solution made especially for the remote, rugged environments without access to a power line.

This device is part of the OleumTech Wireless Sensor Network.

The submersible Side Mount High Level Switch is ideal for point level sensing of refined fuels, crude oil products, chemicals, acids, caustics, lubricants, detergents etc. This product is sold together with both transmitter and switch.

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 High Level Switch 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).
