Product description

  • 0...100 % RH
  • 0...+50 / −20...+50 / −20...+80 / 0...+100 °C
  • Temperature [°C], relative humidity [% RH], absolute humidity [g / m3],
    dew point [°C], mixing ratio [g / kg], wet-bulb temperature [°C]
  • 3 active outputs (0 - 10 V or 4...20 mA)
    1 changeover contact (potential-free, 48 V, 0.1 A,
    switching hysteresis: 2 % of the selected scaling)
  • IP 65 (acc. to EN 60 529)
    >> Housing AND sensing technology <<
Duct sensor HYGRASREG® KFTF-45 with sealed sensor technology (IP 65), with active and switching output, impact-resistant plastic housing with quick-locking screws, cable gland, plastic sintered filter, optionally with/without display, for recording relative humidity (0...100 % RH) and temperature (4 switchable measuring ranges, max. 0...+100 °C) as well as for determining various humidity measurement technology parameters. The measuring transducer converts the measured variables into a standard signal of 0 - 10 V or 4...20 mA.



The device is specially designed for use in harsh environmental conditions (95...99 % RH). A long-term stable, digital humidity and temperature sensor with high impermeability (IP 65 encapsulated) is used. The following parameters are calculated internally from these measured variables and can be called up via the OUT3 output: absolute humidity, mixing ratio, dew point and wet bulb temperature (switchable via DIP switch). With device variant KFTF-45 LCD, up to three parameters can be shown on the display (adjustable via DIP switch).

The sensor is used in medical technology, refrigeration technology, control technology, air conditioning and clean room technology. The sensor is calibrated at the factory; fine adjustment by a specialist is possible depending on the environment.
