Bellow Differential Pressure Gauges

We are distributors and exporters of Bellow Differential Pressure Gauges that meet the requirement of several industries. The 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 and depressions coming in to each bellow. Fabricated in grades of S.S.316 wetted parts, therefore they offer the same corrosion resistance (inside and outside) as the Bourdon Pressure Gauges. These Bellow Differential Pressure Gauges are used for measurements of flow, level, filter clogging, pressure drop measurement, air conditioner & chemical processor and the mechanical resistance of the bellows allows important one-sided overpressure, compare to the differential pressure (up to 20 times in some cases).
