H100-492焊接316L膜片UE压力开关（H100-492 Welded 316L Diaphragm US UE Pressure Switch ）

H100-492 welding 316L diaphragm US UE pressure switch H100-490 H100-491H100-492H100-493H100-494 welding 316L stainless steel diaphragm, 1/2NPT pressure port. Welded stainless steel diaphragm or welded stainless steel bellows structure, omitting the "O" ring, this leak-free design improves fire performance in hazardous explosion-proof areas, while improving pressure resistance. Corrosion-resistant welded diaphragms made of 316 stainless steel, Hastelloy B\C Manganese Alloy and other materials replace ordinary sealing diaphragms in many applications, thus improving the resistance to corrosive solvents, characteristic sodium, salt, organic/inorganic acids, alkalis, Anti-oxidation and anti-corrosion ability under harsh conditions such as seawater. Related terms1. Accuracy: The value indicating the accuracy of the equipment, including linearity, tolerance, hysteresis, repeatability, etc. At present, the highest precision of the long pressure switch can reach ±0.5%FS, and the model is CB33. 2. Maximum pressure (Max.P): the maximum value of the pressure range. 3. Full scale (FS): The difference between the maximum value and the minimum value of the pressure range. 4. Connection difference (dead zone): It refers to the difference between the switch setting action value and the reset value. For example, when the set value is 1MPa and the actual reset value is 0.9MPa, the connection difference is 0.1MPa. 5. Working temperature: refers to the temperature range where the internal mechanism and sensitive components of the instrument will not continue to deform during operation. Generally, the recommended operating temperature range of the pressure switch is -5~400C. If the temperature of the medium is too high, it can be considered to add an accessory siphon (filling shape) to achieve the purpose of cooling. 6.SPDT (Single Pole Double Throw): It consists of a normally open, a normally closed contact and a common terminal.    DPDT (Double Pole Double Throw): It consists of a symmetrical left and right common terminal, and two sets of normally open and normally closed terminals. 7. Upper limit one contact (normally open): When the pressure rises to the set value, the contact will act and the circuit will be conducted. 8. Lower limit one contact (normally closed): When the pressure drops to the set value, the contact will act and the circuit will be turned on.H100-492 pressure switch physical map
