美国UE双点压力开关J402-554J402-550（US UE double point pressure switch J402-554 J402-550 ）

American UE double point pressure switch J402-554 J402-550  UEJ400 series Teflon diaphragm pressure switch UE product advantages:  1. Pressure switch adjustable range from -0.1 to 62MPA 2. Temperature switch from -50 to 538 degrees Celsius3. The adjustable range of the differential pressure switch is from -0.1 to 3.45MPA 4. The sensing element has three types: diaphragm, bellows, and piston5. There are switches for special occasions, and there are also small and low-cost switches specially designed for OEMusers6 . Both fixed dead zone and adjustable dead zone pressure switch7. Some mechanical differential pressure and temperature switches can have on-site indication8. There are 2-inch pressure port anti-blocking switches and sanitary flat diaphragm switches . Working principle pressure switch The working principle: when the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch joint is connected or disconnected by connecting the guide rod. When the pressure drops to or rises to the rated When the value is restored, the disc resets instantaneously, and the switch automatically resets, or in simple terms, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is pushed directly or after comparison to change the on-off of the switch element State, to achieve the purpose of controlling the measured pressure. The elastic components used in the pressure switch include single coil spring tube, diaphragm, bellows and so on. UE pressure switch option M201 factory setting, you need to specify the rise or fall settingM277 kPa or MPa is used as the pressure range unit on the nameplate, factory choice. Not applicable to temperature switchM278, kg/cm2 is used as the pressure unit on the nameplate, not applicable to temperature switchM405 Conforms to European ATEX intrinsically safe standardM406 Complies with Russian Gosgortechnadzor Flameproof Intrinsic Safety Standard M421 Flameproof Junction Box, only suitable for Russian Flameproof Standard M423 ATEX Compliant Flameproof Junction Box M430 Cover Lock M444 Paper Tag M446 Stainless Steel Tag M460 External Earthing Screw; for non-metallic piping systems (ATEX units) M540 Viton (dead band and low pressure range will increase slightly): for sensor type K, sensor type 8, sensor P M541 ethylene propylene rubber (EPDM) O-ring for sensor type 5, 6 and P M550 Oxygen cleaning, internal construction and materials may vary (applicable when including Viton diaphragm and/or O-rings).
