Temperature Humidity Sensor - Anti-condensation Industrial Temperature and Relative Humidity Transmitter HT407 for Demanding Applications – HENGKO

✔ industrial sensors for applications up to 200°C
✔ IP 65
✔ for measuring relative humidity and temperature
✔ with humicap humidity sensing element
✔ with current or voltage output

Designed for use in industrial process automation, the sensors of the HT407 relative humidity temperature sensor can be installed in virtually any position. The robust devices are available to be mounted in ducts, on walls, or are available with a stainless steel probe which can be up to 5 m away from the output electronics. Depending on the application, we either recommend using transmitters with exchangeable or permanently assigned probes. The type of filters and filter materials can be adapted to suit the respective protection category required (up to IP65).

All devices work with an internal processor which uses the measured values for relative humidity and temperatures to also calculated absolute humidity, mixture ratio (water/air) or the dew point (can choose). Digitalization of the signal processing allows the measurement accuracy for humidity to reach excellent values of ±2.0% RH, and with the platinum resistance sensor, the accuracy of the temperature measurement reaches tolerances of ±0.3℃. Depending on the individual design, the sensors can be used at temperatures of between -40 °C and +200 °C and at pressures of up to 10 bar in non-corrosive air.
