the instrument consists of the measuring system (including splice, ripple sylphon, etc.), transmission mechanism(including pull-bar mechanism, gear transmission mechanism), indicating parts (including pointer and dial) and shell (including watchcase, dial ring and the watch glass). Instrument working mechanism is based on a pressure measured medium, its free end produce the corresponding elastic deformation, and then the transmission gear transmit and enlarge the pointer fixed on the gear shaft which will be measured by value indicated on the dial. There have balancing controls which means you can easily adjust zero position.
Diaphragm pressure gauge, also known as micromanometer. it is suitable for measuring non-explosive, non-crystalline, not frozen, and the low pressure on copper and copper alloy corrosion of liquid, gas or steam. Instrument working mechanism is based on a pressure measured medium, its free end produce the corresponding elastic deformation, and then the transmission gear transmit and enlarge the pointer fixed on the gear shaft which will be measured by value indicated on the dial. There have balancing controls which means you can easily adjust zero position.
the mechanism is: by the sensitive element(Bourdon tube, diaphragm capsule, corrugated pipe) of elastic deformation, and then the inner movement conversion mechanism will be conducted to the pressure deformation pointer, causing the pointer ratates to show pressure.
Capsule pressure gauge consists of the measuring system (including splice, ripple sylphon, etc.), transmission mechanism (including pull-bar mechanism, gear transmission mechanism), indicating parts (including pointer and dial) and housing (including watchcase, bushing and tables glass) . Instrument working mechanism is based on a pressure measured medium, its free end produce the corresponding elastic deformation, and then the transmission gear transmit and enlarge the pointer fixed on the gear shaft which will be measured by value indicated on the dial. There have balancing controls which means you can easily adjust zero position. capsule pressure gauge measuring range is -80 ~ 60000Pa, but we need to use different ranges of diaphragm pressure gauge, when the pressure is in -1000Pa ~ 60000Pa, I suggested using disc diaphragm pressure gauge, if the pressure is in -80Pa, a rectangular diaphragm pressure gauge is recommended.
sylphon bellows is impossible not fixed in the watchcase, generally central portion of the diaphragm aperture as the inlet pressure port and fixed, another piece of the center of the diaphragm is the free end of the membrane. membrane is divided into upper and lower free ends, in general it is the lower end of the inlet, then the upper end of the diaphragm sheet is driven by the connecting rod work. .
