Diaphragm pressure gauge

 Diaphragm pressure gauge [1] using the diaphragm as a pressure sensor for measuring small. Measurement corrode copper alloy, non-explosive gas micro-pressure and negative pressure ventilation is widely used in boilers, other similar devices on gas piping, combustion devices. Stainless steel diaphragm pressure gauge pressure system according to the guide and shells are made of stainless steel. Corrosion requirements apply to measure micro pressure and negative pressure of high process in a variety of gaseous media. Stainless steel diaphragm pressure gauge diaphragm pressure gauge with reference to the original structural characteristics of the development of resistant to the corrosive effects of micro-pressure gauge. On used in boiler ventilation and gas pipelines and other equipment, measurement of various gaseous media micro-pressure and negative pressure in the high requirements of the process of decay. Precise [2]: 2.5 Structural principle: This instrument consists of measuring systems (including joints, bellows, etc.), transmission (including pull-bar mechanism, gear transmission mechanism), indicating parts (including pointer and dial) and housing ( including the case, bezel and glass lining) formed. The working principle of the instrument is based on a bellows under pressure measured medium, its corresponding free end of the elastic deformation, and then the transmission gear mechanism and to zoom by fixed gear shaft will be measured by the pointer value indicated on the dial. There are zero means you can easily adjust the zero position. Diaphragm pressure gauge measuring range -80 ~ 60000Pa, but to use different ranges depending on the diaphragm pressure gauge pressure, the pressure in -1000Pa ~ 60000Pa suggested the use of disc diaphragm pressure gauge, if the pressure in -80Pa When suggested the use of a rectangular diaphragm pressure gauge.
