J120-551-M201UE防爆压力开关高炉煤气专用开关（J120-551-M201 UE explosion-proof pressure switch special switch for blast furnace gas ）

Product parameters: J120-551 0.05-19.9KPa 5-199.1mbar Teflon wetted material fluorine rubber O-ring pressure interface 1/4NPTF stainless steel electrical interface 3/4NPTF pressure 1.55MPa explosion-proof pressure switch working principle  explosion-proof pressure switch The explosion-proof effect is achieved 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. Technical parameters: Storage temperature: -54～71℃ Ambient temperature: -40～71℃; or -18～71℃, the ambient temperature changes every 28℃. The typical drift of the set point does not exceed 1% Shock resistance: after 15G, 10 millisecond cycle test. The set point can be reproduced. Vibration resistance: After 2.5G, 5 ~ 500HZ vibration test, the set point can be reproduced. Switch output: a single-pole double-throw (SPDT) fast action switch. Can be connected as "normally open" type" or "normally closed type". Double Pole Double Throw (DPDT) optional on select models. Electrical Rating: 15 Amps. 125/250/480 VAC Electrical Rating: 15A, 125/250/480VAC Electrical Connection: 1/2" NPTF or 3/4 NPTF Pressure Connection port: 1/4"NPTF or 1/2NPTF or sanitary connectionDiaphragm material: welded 316L stainless steel diaphragm, nitrile rubber (Buna-N) diaphragm, fluororubber diaphragm, Hastelloy C diaphragm, manganese diaphragm, tantalum diaphragm, bronze bellows and other pressure interface materials: 316L stainless steel aluminum pressure port nickel-plated brass pressure port explosion-proof pressure switch performance options European ATEX intrinsically safe standard remote temperature switch can choose 50 feet long copper or stainless steel capillary can also choose armored protection cable A variety of switch output options including manual reset, adjustable dead zone, DPDT Red mark shows the current switch is set state application Multi-point switch output for alarm and shutdown or pre-alarm and alarm High/low limit control or liquid level control , water treatment and filtration systems , industrial sterilizers , pump systems and compressors , ideal protection for many other industrial processes and equipment
