Teach you how to identify bourdon tube pressure gauge and pressure gauge

Pressure gauge is mainly the medium pressure, and is widely applied in the industrial equipment, mechanical pressure gauge is mainly due to the elastic sensitive element has high mechanical strength and the characteristics of convenient production. There are many types of pressure gauge, today we mainly about bourdon tube and bellows pressure gauge pressure gauges, teach you how to identify glass tube manometer and bellows pressure gauge. Bourdon tube pressure gauges medium wave pipe sensor is bent into a circular, elliptical section of c-shaped elastic tube. Measurement in wave tube of the inside of the medium pressure, bourdon tube elliptical cross section will be tending to circular cross section. Formed by tube small deformation, wavelengths, a certain ring stress. The ring stress can make the bourdon tube extends outward. As there is no fixed elastic bourdon tube head, it can produce small deformation, the deformation depends on the size of the measuring the pressure of medium size. Bourdon tube deformation through movement indirectly by pointer display measuring the pressure of medium. Bo's pipe pressure gauge is mainly used in industry, petroleum, chemical industry, heating system, pipe pneumatic pipeline and its auxiliary equipment, instrument, etc. Bellows pressure gauge in the bellows sensitive element 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. Membrane and the main measuring corrode the copper alloy, no explosion danger the micro pressure and negative pressure of the gas, widely applied to boiler ventilating, gas pipeline, burning device and other similar devices. How's that？ You can choose now? Actually choose which type of pressure gauge, is mainly determined according to the purpose.
