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.

Contact pressure gauges by WIKA

Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, contact pressure gauges find their application. The switch contacts (also called alarm contacts) make or break circuits dependent upon the pointer position of the indicating measuring instrument.

The switch contacts or alarm contacts in contact pressure gauges make or break the circuit depending on the pointer position. If the reading is significantly above or below a set value, they trigger an alarm (hence also the term alarm contact). They are also suitable for starting, stopping or switching processes.

Magnetic snap-action, inductive and electronic contacts of a contact pressure gauge are usually mounted behind the dial and can be set to any point across the entire scale range via the set pointer. The instrument pointer (actual value pointer) of the contact pressure gauge moves freely. Depending on the instrument version, the switch contacts are factory-set or can be adjusted using an adjustment key in the window.

Depending on the switch contact, contact pressure gauges are distinguished as follows:
