| Information: I. Scope
For oil, water, air, corrosive, viscous fluid and solidification of the place, outstanding head optional fluid-filled diaphragm or not filling two, and can choose the company’s other models are generally stainless steel pressure gauge or seismic pressure gauge and health-based match-body connection.As the diaphragm sheet sealed system filled with liquid as the pressure medium is passed, the temperature of the body as sealing liquid expansion system, the Ministry of the pressure meter with temperature and pressure indication is increased, the amount of its temperature expansion of the liquid and seal coefficient, pressure diaphragm stiffness and the Department of temperature, especially for low-range pressure gauge, then the impact is more evident.General pressure on the provisions of the Department of temperature error is less than 0.1% / C. Therefore, diaphragm pressure gauges overall temperature average temperature by the amount of general-purpose instrument with the diaphragm, the amount of compression of both the Ministry and the temperature.
Main types have a job the word flange, screwed flange, depending on the measurement of media, should choose a different diaphragm and flange materials to ensure that its corrosion resistance, commonly used diaphragm and flange materials SUS316. Mainly used in special working environment such as oil, chemicals, pharmaceuticals, food and other industries.
