Wiring Diagram

Functional principle

The PSD differential pressure sensors have
two pressure connections with ceramic mea­suring cells to detect different pressures, from
which the difference is formed. As a result of
the pressure acting on the measuring cells,
a signal that is proportional to the pressure is
generated and electronically processed inter­nally. Depending on the sensor variant, either
switching or analog signals are available. All
PSD variants have IO-Link.

The PSD sensors operate in various positive
pressure ranges up to a differential of 250 bar.
The connection with higher pressure can be
configured via the menu (High-Site-Switch).
