U.S. UE pressure switches H100 series H100-190 H100-191 Features: * A switch model output * epoxy-coated and cast aluminum structure of the housing meets NEMA 4X standards * Set point lock to prevent misuse * hot track * withstand frost protection level up 10.000psi (689.5bar) * Adjustable pressure range: 30 "Hg Vac to 5000psi (-1 to 344.7bar) micro-pressure 300" wc vacuum to 250 "wc pressure (-746.7 to 622.3mbar ) Differential 0.2 "wcd to 500psid (0.2mbar to 34.5bar) temperature -180 to 650 ° F (-117.8 to 343.3 ℃) Application: H100 Series pressure and temperature switches are property prices are very good series switches are widely used industrial process and OEM customers, the integration of design and shape of the structure to make it more robust housing, wiring more convenient: all-weather series switch has multiple micro switch a variety of process interface options to meet a variety of requirements: use its own characteristics, the 100 series is widely used in heat tracing, frost protection, process devices (pumps, compressors), alarm pad to enter and flames blocking system technical parameters: Storage temperature -54 ~ 71 ℃ ambient temperature of -40 to 71 ℃; 520-525.700-706 type: -18 ~ 71 ℃ 28 ℃ ambient temperature set point changes each typical drift of no more than 1% set point repeatability temperature switch: adjustable within the range of ± 1% pressure switch 171. -174.218.270-376.520-535.700-706.560-564 other models of adjustable range of ± 1%; 190-194.183-189.483-489.565-567.610-680.490-494 other models of adjustable range of ± 1.5%; All pressure switches have internal set-point locking device impact through 15G, 10 ms cycle test. reproducible set point anti-vibration through 2.5G, 5 ~ 500HZ vibration test, reproducible set point casting aluminum shell (copper maximum 0.6 %) with an epoxy coating. interference with stainless steel gasket scale cover. clamping screw shell class in accordance with the requirements NEMA4X.IP65 switch outputs a single-pole double-throw (SPDT) snap action switches can be connected into a "normally open "or" normally closed "Power Rating 15 Amps 125/250/480 VAC weight of 2 to 7 pounds (varies by model) electrical connection 1/2." NPTF interface; 2 7/8 "punching diameter Pressure connector 1/4 "NPTF; 171-194.483-489.520-535 other models for 1/2" NPTF; 560-564 type 2 "sanitary connection; 565-567 type for a 2" sanitary connection temperature Components bulb and capillary: 6 feet 304 stainless steel line: nickel-plated brass (standard length) Optional 316L stainless steel filling Dead toxic oil temperature laboratory conditions F-type switch is typically set point range of 1%. B, C, E-type switch, compared with 2% heat-seeking or frost protection thermometer is specifically for frost protection applications and design. use B100 and E100-type switch can be used to detect the surrounding environment. technical parameters listed on roughly the same type of electricity just B100-13546 rated 22 amps / 480 volt AC switch;. E100-13545 type switch power rating of 22 amps / 480 VAC dimensions of 10 ft long stainless steel capillary.
