Pressure gauge refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the ambient pressure. It is extremely common in applications, and it covers almost all industrial processes and scientific research fields. It can be seen everywhere in the fields of heating pipe network, oil and gas transmission, water and gas supply system, vehicle repair and maintenance factories and stores. Especially in the process of industrial process control and technical measurement, because the elastic sensitive element of the mechanical pressure gauge has the characteristics of high mechanical strength and convenient production, the mechanical pressure gauge is more and more widely used.
Working principle of pressure gauge
The pressure gauge uses the elastic deformation of the sensitive elements (Bourdon tube, bellows, bellows) in the watch, and then the pressure deformation is transmitted to the pointer by the conversion mechanism of the movement in the watch, causing the pointer to rotate to display the pressure.
