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 is the function of ventilation and air-conditioning measuring instruments?

Measuring instruments for ventilation and air-conditioning can indicate any excessive pressure loss due to dirty filters, enable the control of the correct operating state and prevent frost damage to the heat exchangers. In addition, they can be used ...

What happens when a model 7 differential pressure gauge with separation diaphragms made of elastomers is operated below the ambient temperature specified in the data sheet?

Below the permissible ambient temperatures, the accuracy deteriorates significantly, since the diaphragm (which is either made of FPM / FKM or NBR) stiffens at low temperatures.
