COMET T0118 – 4-20mA Indoor Temperature Transmitter -10 to +50 °C

COMET T0118 – 4–20 mA Indoor Temperature Transmitter –10 to +50 °C (±0.5 °C), for KU68 Flush-Mount Boxes, IP20, LCD Switchable 

The COMET T0118 is an elegant and precise 4–20 mA indoor temperature transmitter, specially designed for installation in standard KU68 flush‑mount boxes (used for switches and sockets). Ideal for modern building automation, HVAC systems (heating, ventilation, air conditioning), indoor climate control, offices, hotels, schools, hospitals, or residential buildings where discreet, flush-mounted, and highly accurate temperature measurement is required. The transmitter fits perfectly into standard wall boxes, making it an excellent alternative to conventional room thermostats – with an analog 4–20 mA output for direct connection to controllers, PLCs, BMS systems, or actuators.

The internal temperature sensor measures from –10 to +50 °C with an accuracy of ±0.5 °C and a high resolution of 0.1 °C. The large dual-line LCD displays the current temperature and can be switched off if desired – ideal for representative interior spaces. The output is freely scalable – you can define the measuring range and output value via PC (e.g., 4 mA = –10 °C, 20 mA = +50 °C). The slim, stylish housing (88 × 106 × 33 mm) integrates seamlessly into any room and is designed for indoor use only (IP20). Power supply 9–30 V DC – easily powered via the existing HVAC supply or a central power source.

The transmitter is maintenance-free, long-term stable, and available with a traceable calibration certificate (according to EN ISO/IEC 17025) – top quality for demanding indoor applications. The computer-assisted design ensures permanent stability and fault indication. Installation takes minutes: insert the transmitter into the KU68 box, connect power and the 4–20 mA loop, mount the cover frame – done. No external probe required – everything is housed in one device for maximum reliability and minimal error sources.
