FHF01 is a thin and flexible sensor for general-purpose heat flux measurement. FHF01 is very versatile: it has an integrated temperature sensor and a flexible sensor body fitting flat and curved surfaces. It is applicable over a temperature range from –40 to + 150 °C. FHF01 foil heat flux sensor measures heat flux from conduction, radiation and convection. It is often applied as part of a larger test- or measuring system.

FHF01 measures heat flux through the object in which it is incorporated or on which it is mounted, in W/m². The sensor in FHF01 is a thermopile. This thermopile measures the temperature difference across the flexible body of FHF01. A type T thermocouple is integrated as well. The thermopile and thermocouple are passive sensors; they do not require power.

Using FHF01 is easy. It can be connected directly to commonly used data logging systems. The heat flux in W/m² is calculated by dividing the FHF01 output, a small voltage, by the sensitivity. The sensitivity is provided with FHF01 on its product certificate.
