A Pressure Gauge is a mechanical or digital instrument used to measure and display the pressure of liquids, gases, or steam within a system. It helps operators monitor process conditions and ensure equipment operates within safe pressure limits.
Pressure gauges work by sensing the force exerted by a fluid on a sensing element (such as a Bourdon tube, diaphragm, or pressure sensor) and converting it into a readable pressure value.
They are widely used in:
A Pressure Gauge is an instrument that measures and displays the pressure of fluids or gases in a system, helping maintain safe and efficient operation of industrial processes.
