Diaphragm Sealed Pressure Gauge

Introduction :

A Diaphragm Sealed Pressure Gauge is widely used in industries where direct contact between the pressure sensor and the process fluid could lead to contamination, corrosion, clogging, or measurement errors. The diaphragm seal acts as a protective barrier, ensuring accurate and reliable pressure readings in challenging environments. It features a flexible diaphragm seal that isolates the pressure gauge from the process medium. The gauge consists of a diaphragm seal attached to a Bourdon tube or other pressure-sensing element. These Gauges are suitable for aggressive chemicals, slurries, or viscous media.
