UE压力开关H100-188H100-189（US UE pressure switch H100-188 H100-189 ）

US UE pressure switch H100 series H100-188 H100-189 application: H100 series pressure and temperature switch is a series of switches with very good performance and price, 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 wiring: All-weather series switches have a variety of micro switches and a variety of process interface options to meet various requirements: Using its own characteristics, 100 series are widely used in heat tracking, antifreeze protection, process Devices (pumps, compressors), alarm panel input and flame arresting system. Features: * One switch model output* Epoxy coated and cast aluminum housing meets NEMA 4X standards* Set point lockout Misoperation* Heat tracing level antifreeze protection* Pressure resistance up to 10.000psi (689.5bar)* Adjustable range pressure: 30″Hg Vac to 5000psi (-1 to 344.7bar) Technical parameters: Storage temperature -54～71℃ambient temperature -40～71℃; 520-525.700-706 type: -18～71℃. The typical drift of the set point does not exceed 1% for every 28℃ change in the ambient temperature. Setpoint repeatability Temperature switch: ±1 within the adjustable range %Pressure switch 171-174.218.270-376.520-535.700-706.560-564 and other models are ±1% of the adjustable range; 190-194.183-189.483-489.565-567.610-680.490-494 and other models are ±1.5% of the adjustable range ; All pressure switches have internal set point locking device. Shock resistant to 15G, 10 ms cycle test. Reproducible set pointAnti-vibration After 2.5G, 5～500HZ vibration test, the set point can be reproduced. Housing die-casting aluminum alloy (copper max. 0.6%). With epoxy resin coating. Stainless steel anti-interference scale cover with sealing gasket. Clamping screw housing The level meets the requirements of NEMA4X.IP65. The switch output is a single pole double throw (SPDT) snap action switch. It can be connected as "normally open" or "normally closed" electrical rating 15 amps. 125/250/480 volts AC Pounds (varies by model) electrical connection 1/2" NPTF interface; 2 7/8" diameter punched pressure connection port 1/4" NPTF; models such as 171-194.483-489.520-535 are 1/2" NPTF ; Types 560-564 are 2" sanitary connections; Types 565-567 are 1 1/2" sanitary connections. The main classification is explosion-proof pressure switches, which can be divided into explosion-proof and explosion-proof. The service level 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 type Mechanical pressure switch, the action of the micro switch is caused by purely mechanical deformation. 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.
