- Measuring temperature and relative humidity with a „single-chip“-sensor
- Digital transmission from sensor to the evaluation electronics
- Operational use temperature -40...+120 °C
- Operational use humidity 0...100 %
- Analogue outputs 0...10 V or 4...20 mA
- Sensor interchangeability without need for re-calibration
Humidity-/temperature transmitter in three different cases: for duct-mounting, as outdoor-sensor or room sensor. Output signals 0...10 V in 3-wire technology or 4...20 mA in 2-wire technology.
