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.

How does the measuring system for Model 7 differential pressure gauges with diaphragms behave outside the full scale value?

The plus or minus-sided overpressure safety, up to the maximum working pressure (PN40, PN100, PN250, PN400), is achieved through the metallic measuring element support surface arrangement.  Pressures within the permissible overload range leave no las ...
