| Low Pressure Diaphragm & Capsule Gauges |
 |
Diaphragm gauges are 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 are designed for non-corrosive and non-aggresive 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. |
