What is the function of a pressure gauge?

The function of a pressure gauge is to measure the pressure of fluids or gases within a system. This is essential in various applications, such as monitoring boiler pressure, ensuring system safety, and maintaining optimal operating conditions. Pressure gauges provide critical information to operators, allowing them to make informed decisions and adjustments to equipment to prevent potential failures or accidents.

While other devices may be used for temperature measurement, fuel regulation, or monitoring air quality, these functions are outside the scope of what a pressure gauge is designed to do. The primary focus of a pressure gauge is accurate pressure indication, which is vital for the effective management of fluid and gas systems in industrial and commercial settings.
