4. Design and function

Description
Through the differential pressure to be measured, an unopposed force
is produced on the diaphragm. This measurement force moves the
diaphragm system against the measuring range spring, and the micro
switch is activated via a switch plunger mounted on the diaphragm.
The switch point can be set on the scaled adjustment wheel.
