COMET T0213D – 0-10V Transmitter with 150 mm Duct Probe for Temperature and Humidity

COMET T0213D – 0-10V Transmitter with 150 mm Duct Probe for Temperature –30 to +125 °C, Humidity 0–100 %RH 

The COMET T0213D is a professional 0-10V transmitter with an integrated 150 mm duct probe for temperature, relative humidity, and dew point – the ideal solution for precise climate measurement directly in the airflow of ventilation and air-conditioning systems (HVAC), air ducts, supply or exhaust systems, climate chambers, drying systems, or process air. With an analog 0-10V output and long-term stability, it is perfect for connection to controllers, recorders, PLC inputs, or building management systems – even over long distances without signal loss.

The 150 mm long probe extends deep into the duct and provides representative values even at high air velocities. Temperature is measured from –30 to +125 °C (±0.4 °C), humidity from 0 to 100 %RH (±2.5 %RH from 5–95 %RH at 23 °C). Dew point is internally calculated (±1.5 °C at T<25 °C and RH>30 %). Additionally, all other humidity parameters are available: absolute humidity, specific humidity, mixing ratio, and specific enthalpy. The output is freely scalable – you can define via PC the measurement range and which parameter (T, RH, Tdp, etc.) is transmitted.

The robust IP65 housing (electronics) and the IP40 sensor make the T0213D a reliable partner for demanding use in ducts and HVAC applications (–30 to +80 °C). Galvanic isolation protects against ground loops and interference. The sensors are highly stable over time and available with a traceable calibration certificate (according to EN ISO/IEC 17025) – top quality for critical applications. Wide supply range 15–30 V DC or 24 V AC – fully compatible with most HVAC and modern automation systems.
