Product Name: Six-Lamp Flowmeter Stainless Steel Flow Switch Water, Oil and Gas Model NO.: NK600 Series Media Type: Liquid Type: Thermal Type IP Rating: IP67 Trademark: NOIKE Transport Package: Transport Package Specification: IP67 Origin: Shanghai HS Code: 9026 Product Description Product Overview:Thermal conductivity type flow switch, based on the thermal principle, contains two resistors in aclosed probe, one of which is heated as adetection resistor, the other is not heated as areference resistor, when the medium flows, the heat on the heating resistor 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 effectively prevent the adhesion of scale, rust and other dirt in the pipeline, with stronger anti-fouling ability and more stable work.The unique conical probe design can effectively prevent entanglement in the medium.Fully waterproof housing design, unique waterproof adjustment knob, no need to remove the sealing screw, you can adjust arbitrarily, convenient and reliable.Applicable pipe diameter range is large, set point can be adjusted at will, anti-corrosion type is optional, withstand voltage up to 100bar, indicator light directly displays flow, optional relay, analog output or analog switch integrated output.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 diagramStructure Drawings:Ordering Guide:ModelThreadThreaded interfacePoweredOutputProbePlug-inDetailNK90GElectronic explosion-proof flow switch NK90GG2Thread 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 line
