The transmitter PFT28 converts the measured variables temperature and relative humidity into the measured variables: dew point temperature, absolute humidity, wet bulb temperature and enthalpy.

Output 1 supplies the temperature signal while Output 2 can be assigned to one of four other measured variables. The second measured variable is selected by a two-pole DIP switch.

Measured variable, measured value and unit are displayed on a two-line alphanumeric display.

Two PFT28 versions are available:
A room sensor for wall mounting and a duct sensor for installation in a ventilation duct. In both versions, the sensor tube is mounted directly to the chassis. With a jumper, the output signals can be switched from 0/2...10 V to 0/4...20 mA. The device is powered with 15...30 Vdc or 24 Vac.
