Basic Concepts of Pressure Gauges

A pressure gauge is an instrument used to measure the pressure of a fluid relative to the ambient pressure. It operates based on the principle that a change in pressure causes a corresponding change in the physical properties of the gauge’s sensing element, such as its shape or position. This change is then translated into a readable pressure value, typically displayed on a dial or digital screen. Pressure gauges are fundamental in mechanical systems for ensuring that operations occur within safe and efficient parameters ¹.
