Schaffer Diaphragm Pressure Gauge

We offer Schaffer Diaphragm Pressure Gauges. Schaffer Gauges have a Diaphragm whos displacement is transferred via a link to the movement . These Shaffer Diaphragm gauges have relatively high actuating force.
The annual clamped diaphragm is extensively insensitive to jamming or vibration.A high resistance to over pressure is achieved by underpropint the diaphragm.
Schaffer Gauges are suitable for Pharmaceutical, Chemical, Petrochemical, Oil & Gas, Refinery, Paper & Pulp, Sugar, Breweries, Food & Beverages, Cement Industries, etc
