This is a user manual for the PF4/PF5 differential pressure transmitter
This document is a short instruction manual for the Rotronic PF4 or PF5 multifunctional differential-pressure transmitters. These devices are designed for monitoring and controlling main operating parameters in clean rooms, measuring differential pressure, relative humidity, temperature, and absolute pressure (PF4 only). The text provides guidance on mechanical installation, electrical connections, and menu navigation.
