PFT25

The measuring transmitter PFT 25 converts the directly measured values temperature and relative humidity into often used climatic values dew point temperature, absolute humidity, web bulb temperature and enthalpy by digital calculation.

The device has two analogue outputs, output 1 is always set to temperature, whilst the second output can be set to 4 further values by a two stage dip-switch.

The design of the PFT25 corresponds to the transmitter PFT22.
