A pressure gauge refers to an instrument that uses elastic components as sensitive components to measure and indicate pressures higher than the environment. Its application is extremely common, and it is almost ubiquitous in all industrial processes and scientific research fields. It can be seen everywhere in fields such as heat pipe networks, oil and gas transmission, water and gas supply systems, and vehicle maintenance shops. Especially in industrial process control and technical measurement processes, mechanical pressure gauges are becoming increasingly widely used due to their high mechanical strength and convenient production characteristics of elastic sensitive components.
