Weight: 0.4kgMost Accurate Control By Electronic Thermal Mass Water Flow Switch -----------We are gold supplier in 9 consecutive years CX-FS series Electronic thermal mass flow switch , also known as differential thermal flow sensor and Thermal flow sensor . The set range can be 1-20m/s . Have relay output (230VAC.4A). Suitable for different kinds fluid .Concise and direct indicator ,and with high reliable . The Principle of electronic thermal mass flow switch based on the principle of thermal theory, there are two resistances in the closed probe . One resistance was heated and regarded as detected resistance , the other one was heated and regarded as standard resistance . When the medium is flowing ,the heat on the heated resistance will be taken away and the resistances' value will be changed . The differential resistances value is the basis of determining the flow velocity .Application:gaseous /liquidThe flow switch for ground-source heat-pump is mainly applicable to industrial automation/mechanical equipment/air compressing industry/ refrigeration and air-conditioner. The magnet not contact with flowing water, so can normally work in sewage discharging system.CX-FS-FB Paddle Flow SwitchDiameterDN25…DN150Set range20…1800L/min(water)Repeatability±2.5%FSConnectionterminal typeOutputMechanical switch NO+NC(250VAC,3A)Pressure proof16 barAverage pressure loss:0.08bar( at max.flow rate)Ambient temperature-25…80CMedium temperature0…90CInterface screwG1"pipe screwProtective classIP33Weight0.55kgMaterialMain bodystainless steelProcess connection:brassConnection rodbrassBafflestainless steelSeal NBRHousingABSCX-FS-FB12 Baffle Flow SwitchRepeatability±2.5%FSConnectionterminal typeOutputMechanical switch NO+NC(250VAC,3A)Pressure proof16 barAverage pressure loss:0.08bar( at max.flow rate)Ambient temperature-25…80oCMedium temperature0…90oCInterface screwG1"pipe screwProtective classIP33Weight0.85kgMaterialMain bodystainless steelProcess connection:brassConnection rodbrassBafflebrassSealNBRHousingABSCX-FS-FPD20 Pointer display type piston flow switchMediumliquid or gasRepeatability≤±3%full scalePressure200bar(stainless steel type)100bar(brass type)Outputnormally open outputContact capacity240VAC / 110VDC 1.5AAmbient temperature-20…70oCMedium temperature0…70oCProtectionIP65OutletM12*1MaterialElectronic bodyPCSwitch bodystainless steel / brass nickel platingSpringstainless steelCX-FS-FR11 Electronic Flow SensorSet range1…150cm/s( water),3…300cm/s(oil),20…2000cm/s(air)OutputPNP, NPN, Relay ,4-20mA, NO+NC (SPDT)Power supply24V±20%DC or 230V±15%ACSwitching CurrentMax.400mA(PNP or NPN type ), Max.4A( Relay type )Unload currentMax.80mAFlow indicatorLED (6)Set typepotentiometer setProof Pressure range100barTemperature gradient4oC/sResponse time1--13s,standard is 2sInitialization time8sElectrical protectionreversed-phase ,short circuit ,overload protectionProtection classIP67Medium temperature20--80oCEnvironment temperature-20--80oCStorage temperature-20--100oCConnectionM12 connector /2m cable (option)MaterialProbe is stainless steel .
