UE压力开关H100-560H100-561H100-562（US UE pressure switch H100-560 H100-561 H100-562 ）

US UE pressure switch H100 series  H100-560   H100-561   H100-562    working principle The working principle of the pressure switch: 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 or rises When the rated recovery value is reached, 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 switch element. On-off 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. main category Flameproof The pressure switch can be divided into explosion-proof type and flameproof type. The service grade range is Exd II CT1 ~ T6. Imported explosion-proof pressure switches must pass UL, CSA, CE and other international certifications. It can be used in explosive areas and strong corrosive atmosphere environments. Flameproof pressure switches are available in different pressure, differential pressure, vacuum and temperature ranges. Common applications include electric power, petroleum, chemical industry, metallurgy, boiler, food machinery, environmental protection equipment and other industries. Mechanical The mechanical pressure switch is a purely mechanical deformation that 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 upwards. Through the mechanical structure such as the railing spring, the uppermost micro switch will be activated to output the electrical signal. Features: * One switch model output * Epoxy-coated and cast-aluminum housing meets NEMA 4X standards * Set point lock to prevent misuse * Heat trace level antifreeze protection * Pressure resistance up to 10.000psi (689.5bar) * Adjustable range pressure: 30″Hg Vac to 5000psi (-1 to 344.7bar)   application:  H100 series pressure and temperature switch is a series of switches with very good performance and price. It is widely used in industrial processes and OEM users. The integrated design and the shape and structure of the shell make it stronger and more convenient for wiring. A variety of process interface options to meet various requirements: Utilizing its own characteristics, the 100 series is widely used in heat tracking, antifreeze protection, process equipment (pumps, compressors), alarm panel input and flame resistance break system. technical parameter: Storage temperature -54～71℃ Ambient temperature -40～71℃; 520-525.700-706 type: -18～71℃. The ambient temperature changes by 28℃. The typical drift of the set point does not exceed 1%  Set point repeatability temperature switch: ±1% within adjustable range Pressure switches 171-174.218.270-376.520-535.700-706.560-564 and other models are ±1% of the adjustable range; models such as 190-194.183-189.483-489.565-567.610-680.490-494 are ±1.5% of the adjustable range; All pressure switches have internal set point lockout Shock resistance tested at 15G, 10ms cycle time. Reproducible set point Anti-vibration After 2.5G, 5 ~ 500HZ vibration test, the set point can be reproduced Housing Die-cast aluminum alloy (copper max. 0.6%). With epoxy resin coating.
