WIRELESS THERMOCOUPLE TRANSMITTER

Battery-Powered, Self-Contained Temperature Monitoring Solution

WT-TC1

HIGHLIGHTS

Supports K Type Thermocouple Sensors

The OleumTech® OTC Wireless Thermocouple Transmitter supports third-party type K thermocouple sensors for monitoring extreme heat process conditions including flares, kilns, and gas turbines. The WT-TC1 features 24-bit analog to digital conversion (ADC) and provides a reliable method of measuring temperature. The WT-TC1 provides a junction box and wiring terminal board for accepting a third-party thermocouple sensor. The temperature output can be reported in Fahrenheit, Celsius, or both. The ultra-low-powered transmitter is powered by a replaceable battery pack that provides up to a 10-year life. The push button LCD interface allows for device configuration and instant access to process data.

Reliable, Scalable and Safe

The field-proven wireless transmitter communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network creating a highly scalable network, accommodating virtually any I/O requirement.

The OleumTech wireless transmitter is certified for use in Class I, Division 1 (Zone 0) hazardous locations. It is Intrinsically Safe, designed not to cause a spark, and can be serviced without being removed from a process.

This product is also available without a local display.
