Pressure gauges

Pressure gauges from WIKA – market leader since 1946

Our pressure gauges 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 … 0.2” H2O to 0 … 85,000 psi 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.

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

Pressure gauges for pressure ranges under 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. This pressure in the case le ... More

Why must the differential pressure in model 7 differential pressure gauges with bourdon tubes not be allowed to be less than 1/6 of the full scale value?

For model 7 differential pressure gauges, the static pressure is the same as the full scale value over 270 degrees of rotation. With an expected differential pressure of 1 bar at a static pressure of 10 bar, the two hands would only be separated from each other at ... More
