美國UE指定H122P-S164B-1180防爆壓力開關（US UE designated agent H122P-S164B-1180 explosion-proof pressure switch ）

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. 觸點電氣額定值 15A 125/250/480 VAC（標準）除了型號J120-15622，15834-15839，H121-15875為：20A 125/250/480 VAC；H122P；11A 125/250 VAC；B121-13272，B122-13322，E121-13273， E122-13321;22A 480 VAC。電器開關用于直流電源，觸點容量將會變小。 參考刻度 B，E 和 H 型：外部參考刻度；刻度會隨范圍大小而改變（詳見選型表） 重量 3—8 磅；（因型號而異） 電器接口 H,B,E 型有一個 3/4”NPT；J,C,F,820E,822E 型有兩個 3/4”NPT E/C；標準接線端子 壓力接口 S126B—S164B，171-194，483-494，520-535 等型號的接口為 1/2"NPTF；560-564 型為 2 英 寸園盤衛生等級連接；565-567 型為 1.5 英寸園盤衛生等級連接；540-548 為 1/8"NPT,其它 型號為 1/4"NPTF 溫度組件 溫包及：標準 6 英尺，304 不銹鋼材質；除了 E121-13273 和 E122-13321 為 10 英尺。 插入桿，鍍鎳黃銅（標準）；可選 316L 不銹鋼材質，除了 B121-13272 和 B122-13322 為不 銹鋼。填充，1BS 型：充填溶劑；2BS-8BS：充填無毒油 溫度死區 F120,820E,822E型：典型值為1%；B、C、E-121和122、型：在實驗室條件下，典型值為設 定點范圍的2% 壓力死區 參閱第 5～14 頁的獨立選型表 差壓指示 (選項 M210) H121K 及 H122K 型差壓開關帶差壓指示（選項 M210）；50%量程時大約精度為 1.5%，在端點 兩側時為 3%；指示窗是柔性玻璃材質；指示器可以進行現場調節，其精度為設定點范圍的 1% Temperature indication Model 820E, Model 822E, the indication accuracy is 1% of the full scale
