Exchange sensor available separately
Supply voltage 15...30 Vdc or 24 Vac
Protection class IP 65
The climate transmitter PFT25 converts the directly measured values temperature and relative humidity into often used climatic values dew point temperature, absolute humidity, wet 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.
