Duct temperature sensor PFT22K (duct sensor), measuring rangemax. 160C°, for temperature
Combined humidity/temperature transmitters in three designs: as duct sensor, outdoor sensor or room sensor. Output signals either 0...10 V in three-wire technology or 4...20 mA in two-wire technology.
We offer our PFT22 humidity and temperature transducer in three designs: as a duct sensor, outdoor sensor or room sensor. The sensor has digital signal transmission to the evaluation electronics and the calibration parameters are stored on the sensor chip, which makes it easy to replace the sensor without recalibration. The application range for relative humidity is 0 to 100 % and for temperature -40 to +120 °C. With a response time of a few seconds and 4 calibrated temperature ranges that can be selected via DIP switches, the PFT22 is a reliable measuring instrument. The output signals are either 0-10V in three-wire technology or 4-20mA in two-wire technology.
