5. Operating Principle

The differential pressure sensor PMP is used for controlling and measuring the
differential pressure of air or non-corrosive gases. It is mainly used for the
monitoring of filters and filter cartridges.

The devices are equipped as follows:

Differential Pressure Measurement

The differential pressure is shown on a four-digit LED display.

Limit Value Contact

The devices are provided with two programmable relays for monitoring the
differential pressure. Thus, the magnetic valves for the cleaning cycles can be
piloted or used for programming the alarm pressure.

Analogue Output

For a remote transmission, a 4 to 20 mA output signal is provided.
