A pressure gauge is a mechanical instrument used to measure and display the pressure of liquids or gases within a system. It plays a critical role in monitoring, controlling, and safeguarding equipment by providing real-time pressure information to operators.

Pressure gauges are available in various designs, including bourdon, diaphragm, and capsule types, and can be tailored for specific applications based on pressure range, media compatibility, accuracy class, and environmental conditions. They are widely used across industries such as manufacturing, oil and gas, power generation, chemical processing, HVAC, water treatment, and utilities. By enabling early detection of abnormal pressure conditions, pressure gauges help prevent equipment failure, improve operational efficiency, and ensure safe system performance.
