The operation of this instruments is based on the sensor deflection on which surface a resistance circuit is fixed. The deflection caused by process fluid pressure produces a resistances circuit unbalance, which due to such effect causes a variation of electrical signal proportional to the applied pressure.

Solid front pressure gauges are manufactured as per EN 837-1 and ASME B40.1. During the design of this type of pressure gauges, “safety” factor is taken into great consideration. Safety is guaranteed by a protection baffle wall positioned between the pressure element assembly and the dial, and by a blow-out device made of a back plate which allows an eventual pressure vent from the casing.
