Bellow Differential Pressure Gauges

he pressure element of these instruments has two S.S.316 bellows, balance mounted. The value shown on the dial is the difference between two input pressure or depressions coming in to each bellow. 'MASS' Differential Pressure Gauges are entirely made of S.S.316 wetted parts, therefore they offer the same corrosion resistance (inside and outside) as the Bourdon Pressure Gauges. Moreover the mechanical resistance of the bellows allows important one-sided overpressure, compare to the differential pressure (up to 20 times in some cases).

All differential pressure gauges are used for measurements of flow, level, filter clogging, pressure drop measurement, air conditioner & chemical processor.
