Introduction to Pressure Gauges
Pressure gauges are designed to measure the pressure of a fluid or gas in a system. They consist of a sensing element, a gear train, and a dial or digital display. The sensing element, typically a bourdon tube or a diaphragm, responds to changes in pressure by moving a pointer or activating an electrical signal. The gear train amplifies the movement of the sensing element, allowing for precise pressure measurements. Pressure gauges can be classified into different types, including mechanical, digital, and hydraulic gauges, each with its unique characteristics and applications.
