Heat flux sensor

Typical heat flux plate, HFP01. This sensor is typically used in the measurement of the thermal resistance of and heat flux on building envelopes (walls, roofs). Also, this sensor type can be dug in to measure soil heat flux. Diameter 80 mm
Heat flux sensor mounted on a window. Heat flux sensors can be used like this to determine the R-value or U-value of building envelope materials while they are still installed in buildings.

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.

Silicon encased heat flux sensor for measurements on rugged surfaces

The heat flux can have different origins; in principle convective, radiative as well as conductive heat can be measured. Heat flux sensors are known under different names, such as heat flux transducers, heat flux gauges, or heat flux plates. Some instruments are actually single-purpose heat flux sensors, like pyranometers for solar radiation measurement. Other heat flux sensors include Gardon gauges[1] (also known as a circular-foil gauge), thin-film thermopiles,[2] and Schmidt-Boelter gauges.[3]
