an elastic diaphragm .
The differential pressure (Δp = p
diaphragm against the measuring range springs .
The deflection, which is proportional to the differential pressure, is transmitted to
the movement  in the indicating case via a pressure-tight and low friction rocker
arm .
A magnet , fixed to the rear of the movement, affects the electromagnetic field of
the HALL sensor. The signal that results from this is converted to a standardised
current output signal by the signal conditioning board .
Overpressure safety is provided by metal bolsters  resting against the elastic
diaphragm.
