Pressure Gauge Guard

A pressure gauge guard, also known as a diaphragm seal or instrument isolator, is designed to protect pressure gauges and other pressure instruments from direct contact with aggressive, corrosive, viscous or contaminated process fluids. The flexible diaphragm isolates the process medium while transmitting system pressure to the connected gauge or instrument, allowing accurate pressure measurement without exposing sensitive instrument components directly to the fluid. Pressure gauge guards are commonly used in chemical dosing, water treatment and industrial fluid-handling systems where process media may damage or clog conventional pressure instruments. Depending on the application, different body materials, diaphragm materials and connection configurations are available for chemical compatibility and operating requirements.
