Works with K-Type Thermocouple Sensor

The OleumTech® “SM-TC1” Thermocouple Transmitter supports third-party type K thermocouple sensors for monitoring extreme heat process conditions including flare, kilns, and gas turbines. The SM-TC1 Transmitter features 24-bit analog to digital conversion (ADC) and provides reliable method of measuring temperature. The SM-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. This ultra-low-power transmitter is powered by a replaceable battery pack that provides up to a 10-year life.

Reliable, Scalable and Safe

The field-proven wireless sensor node 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 with a local display.
