Stainless steel shell pressure gauge gb3a8222

The working principle of vacuum meter is based on atmospheric pressure. The muffler of air conditioner is used to measure instruments below atmospheric pressure. Based on the atmospheric pressure, the instrument vacuum gauge used to measure the air pressure greater than or less than the atmospheric pressure can measure the vacuum degree in the intake pipe when the engine is running. The normal operation state of the engine can be judged by the swing state of the pointer. This method can also be used to measure the suction and output pressure of oil pump. Like the cylinder pressure gauge, the main structure of the vacuum pressure gauge also adopts a bodar tube, the unit is expressed as mmHg (mmHg) or CMHG (CMHG), and the normal pressure test end face is expressed as kgf / cm2 by the muffler manufacturer. It is suitable for measuring 316316L and 0crl8ni12mo2ti stainless steel vacuum gauge, gas medium pressure and negative pressure, as well as 316316L and 0crl8ni12mo2ti non corrosive liquid with strong corrosion resistance to the environment. It is used to measure the pressure or negative pressure of liquid, gas or steam which is not corrosive to steel, copper and copper alloy and has no explosion risk. The damping meter is used to measure the negative pressure of non corrosive and non crystalline media under vibration and pressure fluctuation.
