J120-521燃气正负压压力开关美国UE隔爆开关（J120-521 gas positive and negative pressure switch US UE explosion-proof switch ）

J120-521 gas positive and negative pressure switch US UE explosion-proof switch US UE explosion-proof pressure switch can be widely used in petrochemical, offshore platforms, water treatment, medicine, food processing, papermaking, power plants, gas, mining, biology, semiconductors, ships, Defense, pipeline and other industries. When an emergency occurs, the explosion-proof pressure switch sends out a signal to protect the equipment, or it is used in front of some actuators such as valves, or behind components such as bursting discs, and outputs accurate and reliable alarm signals at the first site where there is danger. 120-52X American UE explosion-proof vacuum micro-pressure pressure switch can adjust the action value rubber diaphragm epoxy aluminum coating shell explosion-proof grade Exd IICT6 protection grade IP67.Commonly used models: J120-520 J120-521 J120-522 J120-523 J120 -524 J120-525 pressure interface: standard 1/2NPTF internal thread; can be customized according to site needsElectrical interface: 1/2″NPTF thread interface can be customized according to site needsSwitch output: a single pole double throw ( SPDT) output; 100% can be set separately within the adjustment range; the switch can be connected to "normally open" or "normally closed"ambient temperature: -40℃～+70℃ambient humidity: 5%～95%service life : 100 0000 cyclesMeasuring range: 0～0.01...60 MpaPressure form: gauge pressure, absolute pressureOutput signal: (V) relay contact or low level ≤ 0.5, high level ≥ 4.5 switch signalAccuracy: 0.25 %FS, 0.5%FSSetting range: Lower limit: 0~Upper limit setting minimum value Upper limit: Lower limit setting maximum value~Upper limit setting maximum valueRelay load: 30V/5A DC, 240V/3A ACLong-term stability: (% FS/year) ≤0.5Working voltage: 18～+24(V) Storage temperature: -40～+200 (℃) Working temperature: -20～+80℃, -60～+200℃ (high temperature type) J120-521 pressure switch physical map(responsibility Editor: )
