Product Name: Liquid Flow Meter Gas Flow Meter Thermal Conductivity Flow Meter Electronic Explosion-Proof Flow Switch Model NO.: NK33EX302 Media Type: Gas & Liquid & Oil Type: Thermal Type Certification: Pcec IP Rating: IP67 Trademark: NOIKE Transport Package: Transport Package Specification: IP67 Origin: Shanghai HS Code: 9026 Product Description Product Overview:NK33EX thermal conductivity type flow switch explosion-proof flow switch, based on the thermal principle, contains two resistors in a closed probe, one of which is heated as a detection resistor, the other is not heated as a reference resistor, when the medium flows, the heating resistor The heat is taken away, the resistance value is changed, and the difference between the two resistances is used as the basis for judging the flow rate. The probe adopts anti-scaling coating, which can prevent the adhesion of scale, rust and other dirt in the pipeline, with stronger anti-fouling ability and more stable work.Technical Parameters:Setting range:1…150cm/s (water), 3…300cm/s (oil), 20…2000 (air)Signal output:PNP, NPN, relay, 1) normally open + normally closed (SPDT)Power supply:24V±20%DC2)Power on:Maximum 400mA (PNP or NPN type) Maximum 1A48VAC/DC (relay type)No-load current:Max 80mAFlow indicator:LED row (6)Setting method:potentiometer settingPressure range:100barMedium temperature change:≤4ºC/sResponse time:1…13s, typical value 2sInitialization time:about 8sElectrical protection:reverse phase, short circuit, overload protectionExplosion-proof grade:ExdII CT6Protection level:IP67Medium temperature:-20…100ºCAmbient temperature:-20…80ºCStorage temperature:-20…100ºCWiring mode:M12 connectorMaterial: Probe:Stainless Steel Case: Stainless SteelRepeatability:±2%Wiring diagramNote: The analog output only has DC power supplyOrdering Guide:modelThreadThreaded interfacePoweredOutputProbePlug-inDetailNK33EXElectronic explosion-proof flow switchG2Thread G1/2G4Thread G1/4MRegular thread customizationWInterface thread External threadDDirect current 24V±20%PPNPNNPNGRelayA4-20mARNormally open + normally closed(SPDT)KProbe length customization(15-50mm)QDirect attach lineStructure Drawings:Tips:Support OEM.
