Pressure gauges

Pressure gauges from WIKA – market leader worldwide 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 … 6,000 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

What are the "little yellow levers" on the pressure gauge casing for?

Pressure gauges for pressure ranges under 363 psi (25 bar) generally have a filling plug with small levers. These yellow levers are closed on delivery, and must be opened on fitting, in order to prevent any possible pressure build-up in the case. Thi ...

What is a reed contact (model 851)?

Reed contacts are often used for switching small voltages and currents, since their hermetically-sealed design, in combination with contacts in inert gas, cannot become corroded on the contact surfaces. Their high reliability and low contact resistan ...
