Dial pressure gauge ASME

threadeddiaphragmprocess

Marsh low-pressure diaphragm gauges are globally recognized for their reliable performance and precision with ASME Grade A-1% precision for ranges over 30″ of water. The accessible ranges include vacuum and pressure in inches of water, ounces per square inch and millimeters of mercury. The units adopt a distinctive grid component and a stable safecase structure permitting precise low-pressure readings in broad range of applications. The grid gauges are reactive devices that are utilized in low-pressure applications generally do not go beyond 10 psi. The grid capsule is an elastic metal sensing components consisting of two slim wall grids with its sides soldered to form a capsule. In the vent of air or gas approaching the intake port, it shifts into the grid capsule.
