What is heat flux | How to measure heat flux

Looking for a short introduction to heat flux measurement? Our video explains what heat flux is and how to measure it in different environments and applications. The video also provides guidance: what instrument to use for your measurement and how to choose the right sensor. View all heat flux sensors here: https://www.hukseflux.com/products/he... Measuring heat flux is a powerful tool to gain insights in processes. Hukseflux is the world's market leader in instruments for heat flux measurement. We briefly explain some fundamentals of measuring with heat flux sensors. Heat flux sensors measure energy flux onto or through a surface in [W/m²]. The heat may be transported by conduction, radiation or convection. All heat transfer is driven by temperature differences, flowing from a hot source to a cold sink. Convective and conductive heat flux is measured by letting this heat flow through the sensor. Radiative flux is measured using heat flux sensors with black absorbers; the absorber converts radiative to conductive energy. Hukseflux started in 1993 designing sensors for measurement of heat flux in soils and through walls. In the course of the years, we have added specialised sensors and systems for many other applications. Heat flux sensors manufactured by Hukseflux are optimised for the demands of different applications. The most important variables are: • rated temperature range • rated heat flux range • sensitivity • response time • chemical resistance, safety requirements • size, shape and spectral properties Hukseflux heat flux sensors typically employ thermopiles. Thermopiles generate a signal, as a result of the temperature difference between the hot and cold side of the thermopile. The signal is proportional to the heat flux. Thermopiles are passive sensors; they do not require power. The output usually is a small millivolt signal. Heat flux sensors are applied for good reasons in insulation testing, characterisation of the thermal environment, in fire / flammability / high heat flux, in process monitoring & control and in specialised measurement applications.
