Diaphragm Pressure Gauges are precision pressure measuring instruments designed to measure the pressure of liquids and gases, particularly in applications involving corrosive, viscous, contaminated, or heterogeneous process media. They use a flexible diaphragm as the sensing element to provide reliable pressure indication. Diaphragm pressure gauges are widely used in chemical processing, pharmaceutical, food processing, water treatment, petrochemical, and industrial process applications where conventional pressure gauges may not be suitable.
