H122-612-M201-1010-1010 American UE imported dry contact flameproof mechanical pressure switch double contact double pole Working principle of explosion-proof pressure switch The explosion-proof pressure switch achieves the explosion-proof effect by sealing the wiring contacts in a solid space through a strong sealed shell.  The working principle of the explosion-proof pressure switch is that the pure mechanical deformation causes the action of the micro switch. When the pressure increases, the different sensing pressure components (diaphragm, bellows, piston) will be deformed and will move upward, and finally activate the micro switch on the upper end through the mechanical structure such as the railing spring to output the electrical signal. The setting method is further divided into continuous displacement type and force balance type from the functional principle. Explosion-proof pressure switches can be divided into mechanical explosion-proof pressure switches and electronic explosion-proof pressure switches according to the principle, and mechanical types are divided into ordinary and sealed types.   H122-612UE pressure switch parameters Range range: 0～0.01...60 Mpa Pressure form: gauge pressure, absolute pressure Output signal: (V) relay contact or low level ≤ 0.5, high level ≥ 4.5 switch signal Accuracy: 0.25%FS, 0.5%FS Setting range: Lower limit: 0~Upper limit setting minimum value Upper limit: Lower limit setting maximum value~Upper limit setting maximum value Relay load: 30V/5A DC, 240V/3A AC Long-term stability: ( %FS/year) ≤0.5 Working voltage: 18～+24(V) Storage temperature: -40～+200 (℃) Working temperature: -20～+80℃, -60～+200℃ (high temperature type) Interface: M20*1.5 or user-defined Explosion-proof grade: Exib II CT6 protection grade: IP66 H121-S164B, H122-S164B, H122P-S144B, H121-126, H122-126, H122P-126, H121-134, H122-134, H122P -134,  H121-137, H121-144, H122-144, H122P-144, H121-146, H122-146, H122P-146, H121-156, H122-156, H122P-156, H121-164, H122-164 , H122P-164,H121-358, H122-358, H121-361, H122-361,H121-376, H122-376,H121-612, H122-612, H121-614, H122-614, H121-270, H122-270, H121-274, H122-274, H121-450, H122-450,  H121-452, H122-452, H121- 453, H122-453, H121-454, H122-454 , H121-550, H122-550 555, H121-701, H121-702, H122-702, H121-703, H122-703, H121-704, H122-704, H121-705
