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 movement (4) in the indicator case and to the leaf springs of the microswitches
(5) via a pressure-tight and low friction rocker arm (3).
Overpressure safety is provided by metal bolsters (6) resting against the elastic
diaphragm.
The setting of the switch point is made by the adjustment screws accessible from
the front (7). The assistant scales (8) simplify the setting of the switch points.
