Principle热流分析基于以下原理：如图所示，如果一薄片的热传导率为1(kcal/mh·℃)，厚度为d(m),将其接触在热辐射物表面。Heat当达到平衡后，穿过薄片的热传导强度Q(kcal/m2h或W/m2)Flow可由以下公式得出：Q=λWdX△Td式中△T=薄片两边的温度差，1，d均为已知数据。Principle of the Heat FlowHeat Flow Sensor StructureA heat flow sensor is made of a thin material with a lowthermal conductivity.And its differential ther-mocoupleChromel-alumel wirehas multi-contacts to improve an overrall sensitivity.热导仪中的传感器由低传导率的薄片制成。通过多个接触点消除个别差异从而提高整体精度。Copper wireConstruction of Heat Flow SensorThere will be the most suitable sensor for every requirement!A coverage of each sensosr(application,temp.and heat flow ranges))热流传感器检测范围示意图750In a wall of furnace:700blast fumacehot air fuace600K500,T500500K750,T750温度400electrolytic bath.heat treatment fummetal die.air-conditioner.clectricaTemp.:Cequlpment.etc.300Heat insulation(hot side):200KR.KM,TR,TMAir cooled wall:1000、Water cooled wall:-100Heatinsutation cold sidelBiomedical fieidLNG lanker.retor,cold insulator,etc.TTTTTTTTTTTTm10102101010Heat Flow:W/m2热流3
