by an elastic diaphragm (1).
The differential pressure (∆p = p
diaphragm against the measuring range springs (2).
The deflection, which is proportional to the differential pressure, is transmitted to
the leaf springs of the micro switches (4) in the switch case via a pressure-tight
and low-friction rocker arm (3).
Overpressure safety is provided by metal bolsters (5) resting against the elastic
diaphragm.
The adjustment of the switch point is made by the adjustment screws accessi-
ble from the front (6). The assistant scales (7) enable an accurate setting of the
switch points and indicate the current set point.
