Stainless steel pressure gauges utilize direct contact connectors and pressure-sensing element materials such as ICR18Ni9T, OCr18Ni12Mo2Ti, and SUS316. They feature a fully sealed structure and possess strong resistance to corrosion from the measured medium and the environment. Diaphragm, electrical contact, differential pressure, and flange types can also be customized. Primarily suitable for detecting highly corrosive media suitable for stainless steel components and in harsh external corrosive environments, stainless steel pressure gauges are widely used in petroleum, chemical, and metallurgical industries.

Structural Principle
A stainless steel pressure gauge consists of a pressure-conducting system (including connectors, Bourdon tube, flow-limiting screw, etc.), a gear transmission mechanism, an indicating device (pointer and dial), and a housing (including case, cover, and glass).
The pressure gauge displays pressure by transmitting the elastic deformation of its internal stainless steel sensing element (Bourdon tube, diaphragm, bellows) to the pointer via a mechanism within the gauge's internal movement.
For instruments filled with a liquid (usually silicone oil or glycerin) inside the housing, it can withstand severe vibrations in the working environment and reduce the effects of pressure pulsations.
