Relative humidity and temperature sensor PFT28Ka

absoluteplug-indew-point

• Measurement of temperature and relative humidity • Digital signal transmission from the sensor to the evaluation electronics • Response time of a few seconds • Easy interchangeability of the sensor • Alphanumeric LCD display • Analog outputs 0/2...10 V or 0/4...20 mA • Calculation and display of dew point temperature, enthalpy wet bulb temperature and absolute humidity The transducer PFT28Ka converts the measured variables of temperature and relative humidity into the following parameters: dewpoint temperature, absolute humidity, moisture ball temperature and enthalpy. The device has two analog outputs: Output 1 supplies the temperature signal and one of four further measured variables can be applied to output 2 via two-pole DIP switches. For direct display of the measured value, measured value and unit, the device has a two-line alphanumeric display. Different versions are available: A room sensor for wall mounting, a duct sensor for installation in a ventilation duct and a cable management variant with 2 m cable. In both versions, the sensor tube is installed directly on the housing. The output signals can be switched from 0/2 ... 10 V to 0/4 ... 20 mA with a plug-in bridge. The device is supplied with 15 ... 30 Vdc or 24 Vac.
