Choice of two different sensor technologies (thermal measuring method and diaphragm sensor)
The new differential pressure transmitters PF4 and PF5 with two different sensor technologies (thermal measuring method in PF4 and diaphragm sensor in PF5) consistently produce perfect measurement results thanks to an integrated ambient pressure sensor. Both sensors are equipped with automatic zero point compensation
PF4
The thermal measurement technique of the PF4 transmitter allows exact measurements in the smallest of ranges. The differential pressure transmitter enables Rotronic customers to measure a further important parameter in addition to humidity, temperature, low dew point and CO2.
PF5
The membrane measurement technique of the PF5 transmitter allows exact measurements in the smallest of ranges. The differential pressure transmitter enables Rotronic customers to measure a further important parameter in addition to humidity, temperature, low dew point and CO2.

1 For maximum accuracy, Rotronic recommends you carry out a zero point compensation after installation and commissioning and repeat this every year. Zero point compensation should be carried out more often in aggressive environments/gas media. See the device manual for more detailed information.
2 Zero point compensation is recommended after every change in position and installation (PF5).Model Chart of Rotronic PF4/5
