The OleumTech® TC1 Thermocouple Transmitter supports type K thermocouple sensor for monitoring extreme heat process conditions including flare, kilns, and gas turbines. The TC1 Transmitter features 24-bit analog to digital conversion (ADC) and provides high accuracy of ±0.1 °C. The 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 Thermocouple Transmitter relies on power from a replaceable battery. The system is engineered to achieve maximum battery life, providing +7 years of life from a single battery.


Designed for use in Class I, Division 1 (Zone 0) hazardous locations. The TC1 is intrinsically safe, meaning it cannot a cause a spark and can be serviced without being removed from a process.


The TC1 feature a 32-character local LCD display for instantly reading process data, battery voltage, and RF strength (RSSI). When the display is set to configuration mode, users can set all of its parameters and connect to a network just using the push button interface without the need of any configuration cables.


The OTC Sensor Network is managed using the BreeZ Software by OleumTech, provided free of charge. The Thermocouple Transmitter can be configured using the push button interface or BreeZ Software.


The Thermocouple Transmitter communicates with an OleumTech Wireless Gateway within its network, creating a highly scalable network, accommodating virtually any I/O requirement.
