Bellows pressure switch
16 - 63 bar | SCH
KOBOLD INSTRUMENTATION
With few exceptions In the low pressure range, all pressure
sensors are equipped with measuring bellows, partly made
of a copper alloy but mostly In high stainless steel quality
(1.4571). In comparison with the permissible values, the
measuring bellows are subject to low loads and move only
slightly. This results In long service life with low switching
point drift and high overpressure safety. The movement of the
measuring bellows Is also restricted by an International stop
so that the forces resulting from the overpressure cannot be
transmitted to the switching mechanism.
The parts of the sensor In contact with the medium are wel-
ded together without additional materials and the sensors
contain no seals. Cu bellows which are used for low pressu-
re ranges are soldered to the sensor housing. The sensor
housing and all parts In the unit In contact with the medium
can also be manufactured completely In stainless steel
1.4571 (series DNS). The Individual data sheets contain exact
data on materials.
