Description of stainless steel kpa mmH2O dual micro vacuum capsule pressure gauge

Capsule Pressure Gauges use diaphragm as a sensitive element to measure micro pressure. Measurement corrode copper alloy, non-explosive gas micro-pressure and negative pressure .Widely used in ventilatio boilers, other similar devices on gas piping, combustion devices.

Capsule Pressure Gauges measuring range -80 ~ 60000Pa, but need to use different ranges of diaphragm pressure gauge.Depending on the pressure, the pressure in -1600Pa ~ 60000Pa suggested the use of disc diaphragm pressure gauge, if the pressure in -80Pa ~ 1000Pa suggested the use of the middle of the rectangular diaphragm pressure gauge, if the pressure in -80Pa ~ 1000Pa suggested the use of the middle of the rectangular diaphragm
pressure gauge.

Structure priciple

Capsule Pressure Gauges consist of the measuring system (including joint, bellows, etc.), transmission (including pull-bar mechanism, gear transmission mechanism),indicating parts (including pointer and dial) and housing (including Case, bushing and tables glass) .Instrument working principle is based on a bellows under pressure measured medium, its free end produce the corresponding elastic deformation and then the transmission gear transmission mechanism and to enlarge the pointer fixed on the gear shaft will be measured by value indicated on the dial.There are zero means you can easily adjust the zero position.
