UE switch US UE pressure switch UE explosion-proof pressure switch J120-483 Pressure model table J120 model, internally adjustable, single point switch, two electrical interface  overview   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, 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.   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    Series description  Pressure switch type J120: one single-pole double-throw (SPDT) output; epoxy-coated housing; internally adjustable, no reference scale, two electrical interfaces                    H121 type: one single-pole double-throw (SPDT) output; epoxy coating Shell; externally adjustable, with a reference scale, an electrical interface                    H122 type: two SPDT outputs; epoxy coating shell; externally adjustable, with a reference scale, an electrical interface                  H122P type: two singleThrow (SPDT) output; sealed switch; epoxy-coated housing; externally adjustable, with reference scale, an electrical interface differential pressure switch J120K type: a single-pole double-throw (SPDT) output; epoxy-coated housing; internally adjustable Adjustable, no reference scale, two electrical interfaces                   Type H121K: one single-pole double-throw (SPDT) output; epoxy coating shell; externally adjustable, with reference scale, one electrical interface                    H122K type: two single-pole double-throw (SPDT) Output; epoxy-coated housing; externally adjustable, with reference scale, one electrical interface temperature switch Type B121: in-line; one single-pole double-throw (SPDT) output; epoxy-coated housing; externally adjustable, with reference scale , Single conduit                   B122 type: in-line; two single-pole double-throw (SPDT) outputs; epoxy coating shell; externally adjustable, with reference scale, single conduit                   C120 type: in-line; one SPDT ( SPDT) output; epoxy coated housing; internally adjustable, no reference scale, dual conduit                  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    Sensing element option  N504 316L stainless steel in-line rod, only suitable for 120, 121 type M540 fluorine rubber (Viton) structure, standard pressure port.
