Differential Pressure Transmitter | PF4/5
R19,118.00 – R22,604.00 ex vat
Differential Pressure Transmitter - Overview

The new differential pressure transmitters, PF4 and PF5, use two different sensor technologies (PF4-thermal measuring method, PF5-diaphragm sensor). They consistently produce excellent 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 be ordered with a HygroClip2 connection or a B4 connector for PT100. The colour display allows users to display up to 4 lines and a maximum of 3 measured values. All analogue outputs, inputs and alarm settings can be changed via the intuitive menu. Both device types can be integrated easily into any monitoring system because of the analogue and digital communication abilities. Suitable for heating, ventilation, air conditioning, food industry, pharmaceutical and clean room applications.

Differential Pressure Transmitter - Features
