New: FHF06 heat flux sensor for use up to 250 °C

Hukseflux, the world market leader in heat flux measurement, proudly presents the new FHF06 heat flux sensor. It's the first flex foil sensor that can withstand high temperatures up to 250 °C!

The next level heat flux sensor

The ground-breaking, patented FHF06 heat flux sensor can be used at temperatures up to 250 °C. This next level sensor has an integrated temperature sensor and has thermal spreaders to reduce thermal conductivity dependence. Rated operating temperature range is from –70 to +250 °C. FHF06 measures heat flux from conduction, radiation and convection.

One of its kind

The all-polyimide design makes it possible to use FHF06 up to temperatures of 250 °C. Other members of the FHF family, the FHF05 series, can be used up to 120 °C maximum, which makes the FHF06 unique. The sensor is thin, flexible and versatile. FHF06 measures heat flux through the object in which it is incorporated or on which it is mounted, in W/m2.

Integrated type t thermocouple

The sensor in FHF06 is a thermopile. This thermopile measures the temperature difference across FHF06’s flexible body. A type T thermocouple is integrated as well, to provide a measurement of temperature. The thermopile and thermocouple are passive sensors; they do not require power.

Multiple small thermal spreaders, which form a conductive layer covering the sensor, help reduce the thermal conductivity dependence of the measurement. With these incorporated spreaders, the sensitivity of FHF06 is independent of its environment.

Exceptional features

Using FHF06 is easy. It can be connected directly to commonly used data logging systems. The heat flux in W/m2 is calculated by dividing the FHF06 output, a small voltage, by the sensitivity. The sensitivity is provided with FHF06 on its certificate and at the end of FHF06's cable.

• high temperature resistance up to 250 °C continuous use
• flexible (bending radius ≥ 7.5 x 10-3 m)
• low thermal resistance
• fast response time
• integrated type T thermocouple
• robustness, including connection block, for strain relief
• IP protection class: IP67 (essential for outdoor application)
• integrated thermal spreaders for low thermal conductivity dependence
• sensor foil only: may be used in vacuum

Robust and stable

Equipped with a connection block, which may serve as strain relief, and with potted protective covers on both sides so that moisture does not penetrate, FHF06 has proven to be very robust and stable.
