若何准确应用压力表(国外英文资料).doc

如何正确使用压力表(国外英文资料) Stainless steel seismic pressure gauge adopt direct contact joints and sensing element material, use icr18Ni9T, Ocr18Ni12Mo2Ti, sus316, structure is whole sealing type, stainless steel pressure gauge has strong anti corrosion and environment corrosion resistance measured medium. Stainless steel pressure gauge is suitable for the corrosive strong suited for stainless steel components of medium and severe external corrosion environment, the stainless steel pressure gauge is widely used in petroleum, chemical, metallurgical and other industries. It has a seismic protection rating IP54. IP55. IP65; IP66 The IP protection level is made up of two Numbers, the first number that represents the level of dust and protection against invasion of foreign objects; The second number indicates the degree of inclosure of moisture-proof and waterproof intrusions. The larger the number, the higher the protection level, the level of protection indicated by the two symbols: Features of IP54: dustproof and waterproofing. The first letter is 5: dust proof; The second letter 4 represents: preventing water splattering, Features of IP55: dustproof and waterproofing. The first letter is 5: dust proof; The second letter 5 represents: prevent the injection of water, The IP65 is well sealed; Advantage: dustproof, water spray. Used for earthquake resistant and explosion-proof gauges and situations in which the environment is hostile. The first letter 6 stands for dust and dust seal. The second letter 5 represents: water spray, Features of IP66: dustproof and waterproofing. The first letter 6 stands for dust and dust seal. The second letter 6 represents: preventing the invasion of waves. IP65s shock resistant gauge contains explosion-proof plugs, explosion-proof plugs: Prevent the pipe from being too much pressure, cause the medium to shoot from the pressure gauge front. Classification of pressure transmitter: Table pressure type pressure transmitter: The pressure-transmitter is
