3 Function and application

The (V)PE-... contains a chamber with a dia
phragm.
This diaphragm is subjected to pressure
forces (with PE-...)/tensile forces (with
VPE-...) on one side, and to the clamping force
of the springs on the other side. If the pres
sure or vacuum forces are increased in excess
of the clamping force, a piston connected to
the diaphragm will move and actuate a
changeover switch.

The (V)PE-... can be used as a normally-closed, normally-open or changeover
switch. It has been designed for converting pneumatic pressure values into electri
cal signals which are used for control or monitor functions.
