Differential pressure switch
AFRISO-EURO-INDEX
Suitable for all practically neutral media such as process water, heating
water, neutral gases, oils. Suitable for two-point control by
means of a continuously adjustable switching point (between 10 and
100 % of pressure range).
Function
A robust diaphragm type movement serves as the basis for this unit. It is
suitable for pressure, vacuum and differential pressure measurements.
The unit uses the same principle of operation for all three measuring
applications. The pressure or the differential pressure applies a force
to one side of the diaphragm. This force displaces the diaphragm
system and moves the measurement range spring. A switching
plunger fixed to the diaphragm actuates an electrical switching element.
The switching point is adjusted via a knurled knob according to
the scale.
