PF4 differential pressure transmitter ROTRONIC

Description

PF4 is a differential pressure transducer. It uses the “thermal measurement” method, while PF5 uses the “diaphragm sensor” method.

Thanks to the integrated external pressure sensor, the Nova PF4 and PF5 consistently produce measurement results that are perfect.

Both sensors are equipped with automatic zero point compensation. In PF4 this is done automatically every 5 ms in the sensor, in PF5 the automatic compensation is done by an internal valve and programming in HW4.

Both instruments can also be ordered with a relative humidity sensor connector
HygroClip2
or with a B4 connector for temperature sensors
PT100
.

The new colour display allows users to display up to 4 lines and up to 3 measured values.

All analogue outputs, inputs and alarm settings can be changed or customised via an intuitive menu. Thanks to analogue and digital communication, both types of devices can be easily integrated into any monitoring system.
