Contact pressure gauges

Contact pressure gauges: Switching and indicating with a single instrument

Wherever the process pressure has to be indicated locally and, at the same time, limit values must be monitored, contact pressure gauges find their application. The switch contacts make or break circuits dependent upon the pointer position of the indicating measuring instrument. If the reading is significantly above or below a set value, they trigger an alarm, hence also the term “alarm contact”. Contact pressure gauges are also suitable for starting, stopping or switching processes.

Why is there some white foaming inside the case of liquid-filled pressure gauges?

With liquid-filled pressure gauges, white foam can occasionally form inside the case. This is the well-known phenomenon of an electrochemical reaction between aluminium components (e.g. pointers, dial) and the case filling (mainly with glycerine-wa ...
