Scope:
This manual is valid for the PF4 transmitter series with firmware version V3.x. The low-order digit of the firmware
version stands for minor changes, e.g. correction of errors that do not influence the main functionality of the
device.
1 Overview
The PF4 is a high-precision differential pressure transmitter. The integrated measurement technology is able to
detect very small differential pressures. The measurement results can be shown on the built-in display and
exported via the analog outputs. Optional connection of a HygroClip2 probe, Pt100 sensor or analog input signal
is possible. The isolated change-over switch of a relay can be controlled with configurable alarms.
Main features of the PF4 transmitter:
 High-precision measurement and long-term stability
 Fast response time and low hysteresis
 Freely configurable analog signals
 Isolated integral relay switch contact
 Large overload range
 Optional HygroClip2 connection for humidity, temperature or analog signals
 Selectable units
 High immunity to dust and humidity in the environment
New firmware updates will fix newly discovered issues and add new features. The user is encouraged to stay
up to date with the newest firmware.
