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 indicating case via a pressure-tight and low friction rocker
arm (3).
Overpressure safety is provided by metal bolsters (5) resting against the elastic
diaphragm.
