Bourdon tube pressure gauge: The Bourdon tube sensitive element is an elastic C-shaped tube that is bent into a circular shape and has an oval cross-sectional area. The pressure of the measuring medium acts on the inner side of the wave tube, so that the elliptical section of the Bourdon tube tends to be a circular section. Due to the slight deformation of the Bourdon tube, a certain ring stress is formed. This ring stress causes the Bourdon tube to extend outward. Since the head of the elastic Bourdon tube is not fixed, it will produce a small deformation, and the magnitude of the deformation depends on the pressure of the measuring medium. The deformation of the Bourdon tube shows the pressure of the measuring medium indirectly by the hands through the movement.

Diaphragm pressure gauge: The diaphragm sensitive element consists of two diaphragms with circular waves connected together. The pressure of the measuring medium acts on the inside of the bellows cavity, and the resulting deformation can be used to indirectly measure the pressure of the medium. The size of the pressure value is displayed by the pointer. The bellows pressure gauge is generally used to measure the pressure of gas, and can measure micro-pressure and over-pressure protection to a certain extent. When several bellows sensitive elements are stacked together, a large transmission force is generated to measure extremely small pressures.

Explosion-proof pressure gauge: Explosion-proof pressure gauge is suitable for use in flammable and explosive occasions. It is different from ordinary pressure gauges. Explosion-proof pressure gauges have higher requirements. First of all, the safety factor is not high. There are many types of explosion-proof pressure gauges. How to choose a suitable pressure gauge? Your own pressure gauge, which should be taken into consideration. Explosion-proof pressure gauges are divided into explosion-proof pressure gauges: intrinsically safe explosion-proof pressure gauges and explosion-proof pressure gauges. Safety score: electric contact explosion-proof pressure gauge, pointer type explosion-proof pressure gauge, digital display explosion-proof pressure gauge.

Explosion-proof electric contact pressure gauge: The explosion-proof casing of the explosion-proof electric contact pressure gauge has good explosion-proof performance, so the explosion-proof electric contact pressure gauge can withstand the impact of sparks or arcs during normal operation. The mixture is beyond the explosion pressure generated when the explosion is caused, and can effectively prevent the heat energy generated thereby from spreading smoothly outward, but can only spread out slowly at the tiny gaps along the flameproof joint surface inside the shell. At this time, the instantaneous temperature transmitted to the outside of the casing has been reduced to below the ignition temperature of the explosive gas mixture, so it will not cause detonation.

Explosion-proof digital (pointer) display pressure gauge: high precision, high stability, error ≤ 1%, internal power supply, micro power consumption, stainless steel shell, strong protection, beautiful and delicate. Explosion-proof digital display pressure gauges are widely used in petroleum, chemical, metallurgy, power plants and other industrial sectors or in the matching of mechanical and electrical equipment to measure the pressure of various fluid media with explosion hazards.

Vacuum pressure gauge: The vacuum pressure gauge is used to measure the pressure or negative pressure of liquid, gas or steam medium that has no corrosion effect on steel, copper and copper alloy, no explosion hazard, no crystallization, no solidification. The shock-resistant vacuum pressure gauge is used to measure the negative pressure of non-corrosive and non-crystalline media under vibration and pressure fluctuations. Electric contact pressure vacuum gauge and electric contact vacuum gauge are used to measure the (pressure) and negative pressure of non-crystalline and non-solidified liquids, gases and other media that have no corrosive effect on copper and copper alloys and no explosion hazard. When the pressure reaches a predetermined When the value is set, the control circuit can be turned on or off with the help of the contact device, and an electrical signal can be sent out at the same time.

Classification of vacuum pressure gauges:

Vacuum pressure gauges are based on atmospheric pressure and are used to measure greater and less than atmospheric pressure.
As a classification of shock-resistant pressure gauges, shock-resistant vacuum pressure gauges are used to measure the negative pressure of non-corrosive and non-crystalline media under vibration and pressure fluctuations.

Electric contact vacuum pressure gauge and electric contact vacuum gauge copper and copper alloy have no corrosion effect, non-crystalline and non-solidifying liquid, gas and other medium (pressure) and negative pressure without explosion risk.

The stainless steel pressure vacuum gauge is used to measure the pressure and negative pressure of the liquid and gas medium that are not corrosive to stainless steel 316, 316L and 0Crl8Ni12MO2Ti. All stainless steel has stronger corrosion resistance to the environment.
Acid-resistant pressure vacuum gauge is used to measure the pressure and negative pressure of nitric acid and alkali liquid medium; acid-resistant vacuum gauge is used to measure the negative pressure of nitric acid and alkali liquid.
