The pressure switches operate with a snap-acting switching mechanism which is controlled by a diaphragm and which is adjusted with helical springs. If the set value is exceeded, a contact is activated, deactivated or switched over.
The pressure switches are either permanently set at the factory or can be adjusted by the user himself for a wide range of switching pressures.
The pressure transmitters operate with a piezoresistive pressure sensor as the active element for continuous pressure monitoring. All pressure transmitters optionally have voltage or current interfaces. Certain designs can also be fitted with switching outputs. The manometers are also equipped with a digital display.
