Bourdon pressure gauge refers to a gauge that uses elastic elements as sensitive elements to measure and indicate pressure higher than the ambient pressure. It is widely used, 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 elements of mechanical pressure gauges have high mechanical strength and convenient production characteristics, mechanical pressure gauges have been more and more widely used.
The pressure gauge uses the elastic deformation of the sensitive elements (Bourdon tube, bellows, bellows) in the watch, and the conversion mechanism of the movement in the watch transmits the pressure deformation to the pointer, causing the pointer to rotate to display the pressure .
