COMET T0110 – 4-20mA Temperature Transmitter -30 to +80 °C

COMET T0110 – 4-20mA Temperature Transmitter –30 to +80 °C (±0.4 °C), IP65, galvanically isolated, adjustable, LCD switchable 

The COMET T0110 is a robust 4-20mA temperature transmitter with an integrated sensor – the classic and proven solution for precise temperature measurement in outdoor and indoor areas, building automation, BMS systems, warehouses, technical centers, greenhouses, or process monitoring. With a galvanically isolated current output (4-20 mA) and high long-term stability, it is ideal for connection to PLCs, controllers, recorders, or remote systems – even over long distances without signal loss.

The internal temperature sensor measures from –30 to +80 °C with an accuracy of ±0.4 °C and a high resolution of 0.1 °C. The output is freely scalable – you define the measuring range and output value via PC (e.g., 4 mA = –30 °C, 20 mA = +80 °C). Additionally, you can select between °C and °F. The large dual-line LCD displays the current temperature and can be switched off if needed – ideal for representative or energy-optimized installations. The 53 mm rod probe ensures easy positioning in airflows or protected outdoor areas.

The weatherproof IP65 enclosure reliably protects against dust and water jets – perfect for outdoor use or humid indoor environments (–30 to +80 °C). Galvanic isolation protects against ground loops and interference. The sensor offers long-term stability and is available with a traceable calibration certificate (according to EN ISO/IEC 17025) – top quality for critical applications. Power supply 9–30 V DC (typical 24 V) – simple and flexible via existing HVAC power supply or central power source.
