Description

Technical Field

[0001] The present invention relates to the technical field of pressure gauges, and particularly to an inorganic core pressure gauge. Background Art

[0002] A pressure gauge refers to an instrument that uses an elastic element as a sensitive element to measure and indicate a pressure higher than the ambient pressure. It is extremely widely used and almost covers all industrial processes and scientific research fields. It can be seen everywhere in fields such as thermal pipelines, oil and gas transmission, water supply and gas supply systems, vehicle repair and maintenance factories and shops. Especially in the process of industrial process control and technical measurement, due to the high mechanical strength and convenient production of the elastic sensitive element of the mechanical pressure gauge, the mechanical pressure gauge has been more and more widely used.
