COMET T0211P – 0-10V Transmitter with External Probe for Compressed Air, Temperature, and Humidity

COMET T0211P – 0-10V Transmitter with External Probe for Compressed Air up to 25 bar, Temperature –30 to +105 °C, Humidity, Dew Point, Absolute Humidity 

The COMET T0211P is a precision 0–10V transmitter specifically designed for compressed air applications up to 25 bar, featuring an external hard-anodized duralumin probe (1‑meter cable, optional 2 or 4 m) for temperature, relative humidity, and dew point. As a true compressed-air T+RH sensor with analog 0–10V output, it is the ideal solution for compressors, pneumatic systems, adsorption dryers, refrigeration dryers, process air, or quality monitoring in industrial, automotive, food, pharmaceutical, or workshop environments – perfect for connection to controllers, recorders, PLCs, or BMS systems.

The high-precision capacitive polymer sensor ensures excellent long‑term stability and accuracy: temperature up to +105 °C (±0.4 °C), humidity 0–100 %RH (±2.5 %RH from 5–95 % at 23 °C). The dew point is calculated with high accuracy (±1.5 °C at +10 °C and above). All humidity parameters (absolute humidity, specific humidity, mixing ratio, specific enthalpy) are directly available. The probe is designed for airflows up to 25 m/s (at 1 bar) or 1 m/s (at 25 bar) and is resistant to condensate and oil mist.

The 0–10V output is freely scalable – you can define the measuring range and parameter (T, RH, Tdp, etc.) via PC. The large dual-line LCD displays all measured values. Its robust housing and operating temperature range of –30 to +80 °C make the T0211P a reliable choice for demanding industrial applications. The 1‑meter cable probe allows optimal placement in air lines. Power supply 9–30 V DC – simple and flexible.
