The response pressure results from
the force of the installed adjusting
spring. The upper response pres-
sure (overpressure) is set on the
external spring 1 of the measure-
ment device. The lower response
pressure (vacuum) can be set on
the internal spring 2 . By changing
the setpoint springs, different
response pressures
can be set.
