US UE designated agent H122P-S126B   H122P-S134B   H122P-S144B   H122P-S146B   H122P-S156B   H122P-S164B-1180 explosion-proof pressure switch    summary When selecting industrial pressure, differential pressure or temperature switches, its safety performance is often considered to protect the safety of equipment and personnel. The 120 series products meet UL, CSAATEX and other standards, and can meet the certification requirements of many countries and regions. They can be used in explosive areas and environments containing strong corrosive gases to protect the safety of equipment and personnel. The 120 series can provide different pressure, differential pressure, vacuum and temperature ranges, as well as different connection methods, various materials and pressure sensing element types, precisely because of this flexible choice The 120 series can be widely used in various places, such as chemical industry, petrochemical, oil refining, oil field, drilling platform, oil pipeline and pharmaceutical and other industrial processes.    Features ● Comply with various standard certification requirements, including cULus, ATEX & IECEx ● Optional compliance with Russia, Ukraine and domestic standard certification requirements ● Internal adjustment with reference scale and anti-misoperation For external adjustment of the box cover ● Cover lock with adjustable knob ● SPDT, DPDT or dual SPDT output ● A variety of sensor materials are available ● Hastelloy alloy can be used for strong corrosion places, Monel material ● Large range adjustable dead zone model ● Easy-to-flush sensing element ● Heat trace temperature model ● Fast delivery of most products   technical parameter Storage temperature -65 to 160℉(-54～71℃) Ambient Temperature -58 to 160°F(-50 to 71°C); Models 36-39, 520-525, 540-548, 701-705, 15834-15839: 0 to 160°F (-17 to 71°C); Model 820E, 822E: -40 to 160°F (-40 to 71°C) ambient temperature per Set point typically drifts less than 1% of full scale over a 50°F (28°C) change; less than 2% for E121 and E122 models Setpoint Repeatability Temperature Switch Models B, C, and F: ±1% of adjustable range Model E: ±2% of adjustable range Pressure models 126-164, S126B-S164B, 171-174, 270-274, 358-376, 520-535, 540-543, 560-564, 701-705, 15622, 15834-15839: ±1% of the adjustable range; Model 450-559: ±0.5% of the adjustable range; Models 36-39, 183-194, 483-494, 544-548, 565-567, 612-680, 15875: ±1.5% of adjustable range Shock Resistance Reproducible set point after 10ms, 15G shock test Anti-vibration After 2.5G, 5-500Hz vibration test, the set point can be reproduced Housing Aluminum alloy die-cast housing (Max.0.4% copper); epoxy resin coating; gasket seal; front marked J, G, F switches have internal Internal setpoint lockout; front-marked B, H, E models have misuse-proof airtight aluminum dial cover; aluminum alloy nameplate Enclosure rating The enclosure rating is 4X. Class I, Division 1 switch case rating is 7; Class II, Division 1 switch case Shell rating is 9. IP66. Switch Outputs One or two single-pole double-throw (SPDT) outputs; dual switches can be individually set 100% of the adjustment range; except 822E For this model, its No. 2 switch can only be set within 25% of the No. 1 switch. The switch can be connected as "normally open" or "normally Closed type". Now the optional H122P type is two single-pole double-throw (SPDT) sealed switches. H122P can be applied to two SPDT full Sealed switch. 触点电气额定值 15A 125/250/480 VAC（标准）除了型号J120-15622，15834-15839，H121-15875为：20A 125/250/480 VAC；H122P；11A 125/250 VAC；B121-13272，B122-13322，E121-13273， E122-13321;22A 480 VAC。电器开关用于直流电源，触点容量将会变小。 参考刻度 B，E 和 H 型：外部参考刻度；刻度会随范围大小而改变（详见选型表） 重量 3—8 磅；（因型号而异） 电器接口 H,B,E 型有一个 3/4”NPT；J,C,F,820E,822E 型有两个 3/4”NPT E/C；标准接线端子 压力接口 S126B—S164B，171-194，483-494，520-535 等型号的接口为 1/2"NPTF；560-564 型为 2 英 寸园盘卫生等级连接；565-567 型为 1.5 英寸园盘卫生等级连接；540-548 为 1/8"NPT,其它 型号为 1/4"NPTF 温度组件 温包及：标准 6 英尺，304 不锈钢材质；除了 E121-13273 和 E122-13321 为 10 英尺。 插入杆，镀镍黄铜（标准）；可选 316L 不锈钢材质，除了 B121-13272 和 B122-13322 为不 锈钢。填充，1BS 型：充填溶剂；2BS-8BS：充填无毒油 温度死区 F120,820E,822E型：典型值为1%；B、C、E-121和122、型：在实验室条件下，典型值为设 定点范围的2% 压力死区 参阅第 5～14 页的独立选型表 差压指示 (选项 M210) H121K 及 H122K 型差压开关带差压指示（选项 M210）；50%量程时大约精度为 1.5%，在端点 两侧时为 3%；指示窗是柔性玻璃材质；指示器可以进行现场调节，其精度为设定点范围的 1% Temperature indication Model 820E, Model 822E, the indication accuracy is 1% of the full scale
