The pressure gauge is mainly used for measuring the pressure and vacuum of liquid, gas and steam. The working principle of the pressure gauge is that the spring tube generates elastic deformation under the action of pressure and vacuum to cause displacement of the tube end, the displacement is amplified through a mechanical transmission mechanism and transmitted to an indicating device, and then a pointer points out the measured pressure or vacuum value on an index plate engraved with legal measuring units. The pressure gauges are various in types, and not only have a general (common) pointer indication type, but also have a digital type; not only conventional type, but also special type; not only the contact type but also the remote transmission type; the vibration-resistant type and the vibration-resistant type are provided; there are not only a diaphragm type but also a corrosion-resistant type.
