The principle of bellows pressure gauge, and measurement range

Bellows pressure gauge measuring corrode the copper alloy, no explosion danger, the micro pressure and negative pressure of the gas is widely used in boiler ventilation, gas pipeline, burning device and other similar devices. Today we are here to discuss the working principle of bellows pressure gauge. Bellows of bellows pressure gauge sensor connected by two pieces of circular waves of diaphragm. Measuring cavity inside the membrane box, medium pressure deformation caused by the medium can be used to indirectly measure the pressure. The size of the pressure value showed by the pointer. Bellows pressure gauge are commonly used to measure the pressure of the gas, and can measure micro pressure, over voltage protection to a certain extent, is also possible. When several bellows sensitive element fold together will produce larger to measure the pressure of the tiny heritability. Bellows pressure gauge measuring range: ( Unit: kpa) 0 ~ 2. 5; 0 ~ 4; 0 ~ 6; 0 ~ 10; 0 ~ 16; 0 ~ 25; 0 ~ 40; 0 ~ 60; - 2. 5 to 0; - 4 to 0; - 6 ~ 0; - 10 ~ 0; - 16 ~ 0; - 25 ~ 0; - 40 ~ 0; - 2 ~ 2; - 3 ~ 3; - 5 ~ 5; - 8 ~ 8; - 12 ~ 12; - 20 ~ 20 - 30 ~ 30
