COMET T0213 – 0-10V Transmitter with 150 mm Duct Probe for Temperature and Humidity

COMET T0213 – 0-10V Transmitter with 150 mm Duct Probe for Temperature –30 to +125 °C, Humidity 0–100 %RH, Dew Point, 24 V AC/DC, IP65 

The COMET T0213 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 (AHU), air ducts, supply or exhaust systems, climate chambers, drying processes, or process air. With an analog 0-10V output and high long-term stability, it is perfect for connection to controllers, recorders, PLC inputs, or BMS systems – even over long distances without signal loss.

The 150 mm long probe extends deep into the duct and provides representative readings 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 % at 23 °C). The dew point is calculated internally (±1.5 °C at T<25 °C and RH>30 %). All other humidity parameters are also available: absolute humidity, specific humidity, mixing ratio, and specific enthalpy. The output is freely scalable – you define the measuring range and which variable (T, RH, Tdp etc.) is transmitted via PC configuration.

The robust IP65 housing (electronics) and IP40 sensor make the T0213 a reliable partner for demanding applications in ducts and air handling systems (–30 to +80 °C). Galvanic isolation protects against ground loops and interference. The sensors offer excellent long-term stability and are available with a traceable calibration certificate (according to EN ISO/IEC 17025) – ensuring the highest quality for critical applications. Wide supply range 15–30 V DC or 24 V AC – compatible with most ventilation and HVAC systems.
