How do heat flux sensors work
WebHow heat flux sensors work. External video URL. Heat flux sensors measure a temperature difference across a thin layer of material. They typically employ a thermopile, which is manufactured by creating an alternating pattern of two dissimilar conductors, generally metal alloys. The output is a millivolt signal proportional to the local heat flux. WebThe Heat Flux Sensorgenerates a voltage signalwhich is proportional to the heat that passes through the sensor elementsuch as HF = V / Swhere HF = Heat Flux, in W/m2 V = Voltage, in µV and S = Sensor sensitivity, in …

You will learn more about what heat flux is,... WebHeat flux gauge. (a) A schematic; (b) a foil heat flux sensor with K-type thermocouple (Omega™). (6.7) where L is the thickness of the solid (plate) that the heat flow penetrates through. This is called the differential temperature heat flux measurement technique. Other available techniques can be found (Childs, 2001 ).
A heat flux sensor is a transducer that generates an electrical signal proportional to the total heat rate applied to the surface of the sensor. The measured heat rate is divided by the surface area of the sensor to determine the heat flux. The heat flux can have different origins; in principle convective, radiative as well as … See more Heat flux sensors are used for a variety of applications.
