Thermocouple Transmitter

Made especially for the remote, rugged environments without access to a power line. Virtually any third-party K Type thermocouple sensor can be wired-up through its junction box.

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 Thermocouple Transmitter is a self-contained, battery-powered temperature measurement solution using K Type Thermocouple sensor and is made especially for the remote, rugged environments without access to a power line. Virtually any third-party K Type thermocouple sensor can be wired-up through its junction box.

This device is part of the OleumTech Wireless Sensor Network.

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 Thermocouple 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).
