FHF06 is a high-temperature foil heat flux sensor engineered for temperatures up to 250 °C. This capability is made possible by its all-polyimide design, without using any glues. Other members of the FHF family, such as the FHF05 series sensors, are rated for use up to 120 °C. Like all FHF sensors, FHF06 is thin, flexible, and versatile.
FHF06 measures heat flux (in W/m2) either through the object in which it is incorporated or on which it is mounted. Each sensor contains a thermopile that measures the temperature difference across FHF06’s flexible body, which directly translates to heat flux. An integrated Type T thermocouple provides additional temperature measurement. Both the thermopile and thermocouple are passive sensors and do not require external power.
Multiple small thermal spreaders form a conductive layer covering the sensor, reducing the thermal conductivity dependence of the measurement. With these incorporated spreaders, the sensitivity of FHF06 is independent of the thermal properties of its environment.
Using FHF06 is easy. It connects directly to commonly used data logging systems. The heat flux (in W/m2) is calculated by dividing FHF06’s output, a small voltage, by the sensitivity, which is provided on its certificate.
