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. Operating Mode: Measured material: Sensor: Measuring unit Output signal 1 Output signal 2 Response time: Reproducibility: Tolerance: Measuring ranges: Measuring range selection: Characteristics: Transmitter PFT22R as room sensor with 2 x 0...10 V output Resolution: Response time: Reproducibility: Tolerance: Measuring range: Characteristics: TECHNICAL SPECIFICATIONS: Measuring mode Temperature and humidity Single-chip sensor for humidity and temperature with digital signal transmission and calibration memory on the chip Temperature in ° C; relative humidity in % Temperature Relative humidity TEMPERATURE FEATURES: 14 bit Approx. 20 Sekunden ± 0,1 °C ±0,5 °C at 25 °C; ±2 °C at -40 °C, ±3 °C at +120 °C; narrower tolerance possible -40...0...+120 °C; -30...0...+70 °C; 0...100 °C; 0...50 °C 4 selectable measuring ranges via DIP switch Linear HUMIDITY FEATURES: 12 bit Aprrox. 4 seconds (63 %-time, slightly moving air) Typical < 1 % r.h. / Jahr ± 0,1 % r.h. 0...100 % relative humidity Linear (digital linearization) Transmitter PFT22R as room sensor with 2 x 4...20 mA output KOutdoor sensor PHYSICALLY: See drawings Plastic ABS 7 Connection terminals Sensor tube: stainless steel, 11 mm 0 Protection class: IP 65 according to EN 60529 Cable gland: M16 x 1.5 Sensor tube: double-walled sensor tube with wall holder Protection class: IP 65 according to EN 60529 Cable gland: M16x1.5 Date: 13.02.17 HUMIDITY Room sensor Power supply: Output current: Plastic housing for mounting on a flush-mounted switch box or surface-mounted wall mounting ELECTRONIC: 15 ... 30 Vdc or 24 Vac in three-wire circuit; 13 ... 30 Vdc in two-wire circuit 2 x 0 ... 10 V in three-wire circuit; 2 x 4 ... 20 mA in two-wire circuit RoHS: according RoHS-directive 2011/65/EU Arthur Grillo GmbH • Am Sandbach 7 • 40878 Ratingen • phone 0 21 02 - 47 10 22 • fax 0 21 02 - 47 58 82 www.grillo-messgeraete.de/en • Email: info@grillo-messgeraete.de • web shop: www.sensor-store.de
