The diaphragm-sealed pressure gauge is an advanced pressure measurement instrument designed specifically for accurate readings in challenging applications. Ideal for measuring the pressure of corrosive, high-viscosity, and easily crystallizing media containing solid particles, this gauge protects against direct exposure to the medium, preventing blockage and corrosion. Comprising two essential components—a standard pressure gauge and a diaphragm sealing device (which includes the diaphragm body, diaphragm sheet, and sealing fluid)—this product is commonly utilized across various industries, including petrochemicals, metallurgy, pharmaceuticals, food and beverage, and papermaking, At the heart of the diaphragm-sealed pressure gauge is the mechanism of pressure transmission via diaphragm deformation. Upon contact with the measured medium, the pressure exerted causes the diaphragm to deform elastically. The sealing fluid, typically silicone oil or glycerin, conveys this deformation pressure to the elastic sensing element, such as a Bourdon tube, within the pressure gauge. As pressure varies, the elastic sensing element produces a corresponding displacement, which drives the pointer to indicate the pressure value through an internal transmission mechanism, As a leading factory in China, we pride ourselves on delivering high-quality diaphragm-sealed pressure gauges.
