What is a Pressure gauge?

A pressure gauge is a device that measures the pressure of a fluid such as air or water. Pressure is measured mainly by measuring the amount of deformation of the elastic body inside the pressure gauge due to pressure. Various principles have been developed for measuring the amount of deformation, including the Bourdon tube type, diaphragm type, and bellows type. There are various types of pressure such as constant pressure, fluctuating pressure, and pulsating pressure, and there are absolute pressure, gauge pressure, and differential pressure depending on how to take the zero point. It is necessary to pay attention to the display method and select an appropriate pressure gauge. By the way, the one that measures positive gauge pressure is called a pressure gauge, and the one that measures negative gauge pressure is called a vacuum gauge.

Application of Pressure gauge

Pressure gauges are used in pressure-sensitive devices such as factories, plant pipes, and homes. It is necessary to make an appropriate selection according to the environment in which the pressure gauge is operated and the gap. An example of using the pressure gauge is shown below.
