What is the function of a pressure gauge?

The function of a pressure gauge is to measure and display the pressure of a fluid within a system. This instrument provides critical information regarding the operating conditions of equipment and processes, ensuring that everything functions safely and efficiently. Accurate pressure readings are essential for proper system performance, as both low and high-pressure conditions can lead to equipment failure, process inefficiencies, or safety hazards. In industrial settings, pressure gauges are widely used to monitor the pressure in various systems, such as pipelines, reactors, and boilers, allowing operators to make informed decisions based on real-time data. By providing an accurate reading of fluid pressure, a pressure gauge plays a vital role in maintaining system integrity and operational safety.
