Working principle
The principle of vacuum pressure gauge is mainly based on the corresponding elastic deformation of the corrugated diaphragm box under the pressure of the measured medium. ‌ the deformation is amplified by the dial-gear transmission mechanism, ‌ the pointer fixed on the gear shaft indicates the measured value on the dial. ‌ this pressure gauge and pressure by the guide system (‌, ‌ spring tube, including joint ‌ current-limiting screws, etc.), ‌ ‌ gear transmission mechanism in several device (‌ pointer and dial) ‌ and the shell (‌ atlas, ‌, ‌ table glass lid, etc.) of ‌. ‌ The shell is usually of airtight construction, ‌ can effectively protect the internal parts from environmental influences and pollution intrusion. ‌ For the instrument filled with liquid in the housing, ‌ can resist the vibration of the working environment and reduce the influence of media pressure pulsation. ‌

Product Feature
1、Material: ‌
adopts full stainless steel material, use 0 cr18ni9 ‌ if joint (304) ‌ ‌ or 0 cr17ni12mo2 (316) ‌ ‌, ‌ bourdon tube use 0 cr18ni9 Ti (321) ‌ ‌ or 0 cr17ni12mo2 (316) ‌ ‌, ‌ shell also USES 0 cr17ni12mo2 material, ‌ has good corrosion resistance and mechanical strength. ‌
2、Explosion-proof and shock-proof: ‌
designed for shock-proof and explosion-proof instruments and harsh site environment occasions, ‌ with IP65 or IP66 protection grade, ‌ can prevent dust and water intrusion, ‌ provides additional safety protection. ‌
3、Temperature compensation: ‌
In some models, ‌ adopts the pressure measurement method with temperature compensation, ‌ to detect and control the pressure corresponding to a certain density value of liquid or gas in a sealed container, ‌ to realize the monitoring of gas density. ‌ This characteristic enables the gauge to maintain accurate measurements in environments with varying temperatures. ‌

Stainless steel oil free pressure gauge is widely used in petroleum, ‌ chemical industry, ‌ shipbuilding, ‌ metallurgy, ‌ power station and other industrial sectors, ‌ corrosion resistance, ‌ anti-vibration requirements of high process to measure the pressure of various fluid media.

Maintenance
1、After a period of use and pressure, the pressure gauge movement will inevitably appear some deformation and wear, and the pressure gauge will produce various errors and failures. In order to ensure its original accuracy without distortion of the quantity transfer, it should be replaced in time to ensure that the indication is correct, safe and reliable.
2、The pressure gauge should be cleaned regularly. Because the inside of the pressure gauge is not clean, it will increase the wear of various parts, which will affect its normal work, and seriously make the pressure gauge fail and be scrapped.
3、If the medium in the pressure measuring part fluctuates greatly, the use is frequent, the accuracy requirements are high, and the safety factors are strictly required, the verification cycle can be appropriately shortened according to the specific circumstances.
