Description

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. In the PF4, this is carried out automatically every 5 ms in the sensor, in the PF5 automatic compensation is performed with the help of an internal valve and programming in the HW4 V3.9.0. Both instruments can also be ordered with a HygroClip2 connection or a B4 connector for PT100. The new color display allows users to display up to 4 lines and a maximum of 3 measured values. All analog outputs, inputs and alarm settings can be changed via the intuitive menu. Thanks to analog and digital communication, both device types can be integrated easily into any monitoring system. Advantages • Flow or diaphragm differential pressure sensors • 1 to 3 analog outputs, 1 analog input • Network-compatible (Ethernet) • Modbus capable TCP or RTU via RS485 • Potential-free relay with changeover contacts Use cases • Heating, ventilation, air-conditioning technology • food industry • pharmaceutical sector • clean rooms
