HUMIDITY & TEMPERATURE TRANSMITTER PFT22 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. Specifications Sensor Humidity Solution: Reproducibility: Tolerance: Characteristic: Response time: Hysteresis: Long-term stability: Transmitter PFT22R as room sensor with 2 x 0...10 V output Temperature Solution: Reproducibility: Tolerance: Characteristic: Response time: 4 selectable range: Voltage outputs: Power output: Transmitter PFT22R as room sensor with 2 x 4...20 mA output Single-chip sensor for humidity and temperature with digital signal transmission and calibration memory on the chip 12 bit ± 0,1 % RH ± 3,5 % RH in the area 30...70 % RH, ± 5 % RH to the area limits narrow tolerances (± 2 %, ± 4 %) possible linear (digital linearisation) approx. 4 second (63 % time,) slightly moving air ± 1 % RH typical < 1 % RH / year 14 bit ± 0,1 °C ± 0,5 °C at 25 °C ± 2 °C at -40 °C, ± 3 °C at +120 °C narrow tolerances possible linear approx. 20 seconds -40...0...+120 °C -30...0...+70 °C 0...100 °C 0...50 °C 2 x 0...10 V in 3-wire circuit 4 connection terminals supply voltage 15...30 Vdc or 24 Vac 2 x 4...20 mA in 2-wire circuit 3 connection terminals supply voltage 13...30 Vdc tested according EN 61000-6-2, EN 61000-6-3, CE mark Duct sensor sensor tube of stainless steel, 11 mm ø connection head plastic ABS gland M16x1,5 Outdoor sensor double-walled sensor tube with wall holder connection head plastic ABS gland M16x1,5 Room sensor plastic case for wall mounting
