The 120 series products meet UL, CSA, ATEX 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-sensitive element types. It is precisely because of this flexible choice that the 120 series can be used in a wide range of applications. Used in various places, such as chemical industry, petrochemical, oil refining, oil field, drilling platform, oil pipeline and pharmaceutical and other industrial processes.   Model parameters:   Features  ● Compliance with various standards certification requirements, including cULus, ATEX & IECEx    ● Optional compliance with Russian, Ukrainian and domestic standard certification requirements     ● Internal adjustment with reference scale and external adjustment with anti-misoperation cover    ● Cover with adjustable knob Lock    ●SPDT, DPDT or dual SPDT output    ●A variety of sensor materials are optional    ●Hastelloy and Monel materials can be used for strong corrosion sites    ●Large range adjustable dead zone model   ●Easy to wash sensor element    ●Heat tracking temperature model    ● Fast delivery of most products  系列 描述  壓力開關 J120型:一個單刀雙擲(SPDT)輸出;環氧涂層外殼;內部可調,無參考刻度，二個電氣接口                    H121型:一個單刀雙擲(SPDT)輸出;環氧涂層外殼;外部可調,有參考刻度，一個電氣接口                    H122型:二個單刀雙擲(SPDT)輸出;環氧涂層外殼;外部可調,有參考刻度，一個電氣接口                   H122P型:二個單刀雙擲(SPDT)輸出;密封型開關;環氧涂層外殼;外部可調，有參考刻度，一個電氣接口  差壓開關 J120K型: 一個單刀雙擲(SPDT)輸出;環氧涂層外殼;內部可調,無參考刻度，二個電氣接口                    H121K型: 一個單刀雙擲(SPDT)輸出;環氧涂層外殼;外部可調,有參考刻度，一個電氣接口                    H122K型: 二個單刀雙擲(SPDT)輸出;環氧涂層外殼;外部可調,有參考刻度，一個電氣接口  溫度開關 B121型：直插式；一個單刀雙擲(SPDT)輸出;環氧涂層外殼;外部可調,有參考刻度，單導線管                   B122型：直插式；二個單刀雙擲(SPDT)輸出;環氧涂層外殼;外部可調,有參考刻度，單導線管                   C120型：直插式；一個單刀雙擲(SPDT)輸出;環氧涂層外殼;內部可調,無參考刻度，雙導線管                  Type E121: bulb and capillary; one SPDT output; epoxy-coated housing; externally adjustable, with reference scale, single conduit                  Type E122: bulb and capillary; two SPDT ( SPDT) output; epoxy-coated housing; externally adjustable, with reference scale, single conduit                    Type F120: bulb and capillary; one single-pole double-throw (SPDT) output; epoxy-coated housing; internally adjustable, without Reference scale, dual-conduit                   Model 820E: bulb and capillary; one SPDT output; externally adjustable with temperature indicator, dual-conduit                     Model 822E: bulb and capillary; two SPDT (SPDT) output; externally adjustable, with temperature indicator, dual conduit    Features  ● Compliance with various standards certification requirements, including cULus, ATEX & IECEx    ● Optional compliance with Russian, Ukrainian and domestic standard certification requirements     ● Internal adjustment with reference scale and external adjustment with anti-misoperation cover    ● Cover with adjustable knob Lock    ●SPDT, DPDT or dual SPDT output    ●A variety of sensor materials are optional    ●Hastelloy and Monel materials can be used for strong corrosion sites    ●Large range adjustable dead zone model   ●Easy to wash sensor element    ●Heat tracking temperature model    ● Fast delivery of most products
