Pressure gauges from WIKA – market leader since 1946

Our pressure gauges (mechanical pressure measuring instruments) for gauge, absolute and differential pressure have been proven millions of times over. For the optimal solution for the widest range of applications, there is a choice of measuring systems in Bourdon tube, diaphragm element and capsule element technologies. The pressure gauges cover scale ranges from 0 … 0.5 mbar to 0 … 7,000 bar and indication accuracies of up to 0.1 %. For the various requirements in industrial and process instrumentation there are pressure elements from copper alloys, stainless steel or special materials available.

FAQ

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

When should a restrictor be used?

For pressure spikes or sudden pressure loading and unloading.
