Differential pressure gauges with Bourdon tube element

 

Service intended: Measurement of pressure differential of 2 pressures applied. Suitable for gaseous and liquid, non-crystallizing media that will not obstruct the pressure system. Scale range must be selected in consideration of the highest static pressure applied. When ordering please state both, the static pressure applied and the differential pressure.
