A diaphragm is a more mechanically stable element than a bourdon tube and can stand mechanical shock with less damage. Diaphragm Pressure Gauges can be used to indicate pressures below those practical for bourdon tube pressure gauges.
The diaphragm can be protected against aggressive liquids and gases by fitting a thin flexible disc of resistant material as a barrier between it and the corrosive media. The pressure chamber or base can be made from a suitable material. A Diaphragm Gauge is technically preferable to using a Bourdon Tube Pressure Gauge fitted to a chemical seal.
The PG 100 Pressure Gauge is a reliable industrial pressure measurement solution designed for accurate and dependable monitoring of process pressure. It features a Bourdon sensing system with ‘C’ and coiled Bourdon tube construction and is available in multiple dial sizes for different installation requirements.
