Low Pressure Diaphragm Gauges

 Low Pressure Diaphragm GaugesWe are distributor and supplier of Low Pressure Diaphragm & Capsule Gauges to meet the variegated requirement of buyers coming from different industries. These are very suitable for measuring pressure of all kind of fluid and gaseous medium. The measuring element is a sensitive corrugated diaphragm fixed between two flanges. For slurry and viscous liquids flanged connections can also be incorporated. Low Pressure Bellow Capsule Gauge is designed for non-corrosive and non-aggressive application. These Gauges have bellow capsule which is composed of two corrugated metal discs of Brass / Stainless Steel joined by brazing / argon arc welding. A rise pressure will cause the corrugated Capsule / Diaphragms to expand and this motion is transferred to the indicator through sector, pinion movement mechanism. A similar type of low pressure built-in capsule gauge can also be offered having almost similar kind of mechanism.Specification Dial size 100mm, & 150mm Accuracy 11.5% and+2% of the f.s.d.
