UEJ120-361-M201防爆不锈钢压力开关（UE J120-361-M201 Explosion Proof Stainless Steel Pressure Switch ）

UE J120-361 is an explosion-proof pressure switch, the explosion-proof grade is Exib II CT6, the protection grade is IP66, and the wetted material is 316 stainless steel. Certificate of origin, customs declaration documents, explosion-proof certificate and SIL2 certification can be provided. 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. ??   SPDT (Single Pole Double Throw): 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. Upper limit one contact (normally open): When the pressure rises to the set value, the contact will act and the circuit will be turned on. 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.  0140 Gold contacts M201 factory setting, need to specify the rising or falling setting The M277 nameplate uses kPa or MPa as the pressure range unit, factory selected. not suitable for temperature switches M278 uses kg/cm2 as the pressure unit on the nameplate, not applicable to temperature switches M405 complies with European ATEX intrinsically safe standards M406 complies with the Russian Gosgortechnadzor flameproof intrinsically safe standard M421 explosion-proof junction box, only suitable for Russian explosion-proof standards M423 ATEX Compliant Flameproof Junction Box M430 Lid lock M444 Paper Signs M446 stainless steel tag M460 external grounding screw; for non-metallic piping systems (ATEX installations) M480 differential pressure switch type K, 316 stainless steel pressure port, sensor material cannot be changed.
