Contact pressure gauges

WIKA 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 the circuit 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.

FAQ

What is an electronic contact (model 830.E)?

Electronic contacts are fitted with non-contact slot sensors. They are especially suitable for oil-filled gauges and should be preferred for low voltages and small DC loads, such as for the signal input for a PLC (programmable logic controller).

How low is the temperature of the medium which is stored inside the cryogenic vessel when it reaches the pressure gauge?

A Cryo gas is a gas which is gaseous at ambient temperature and pressure and becomes liquid because of cooling and compression. Due to cooling and compression the volume of the gas can be reduced and thus it’s possible to store a huge quantity inside a ves ... More
