FHF05 Flexible Foil Heat Flux Sensors with Thermal Spreaders and Temperature Sensor

The FHF05 Foil heat flux sensors with thermal spreaders, flexible, different dimensions, with temperature sensor is the product range to start looking if you consider measuring heat flux. Models are available in five different dimensions and sensitivities. All FHF05’s are flexible, have an integrated temperature sensor and have thermal spreaders to reduce thermal conductivity dependence. Rated temperature range is from –70 to +120 °C. FHF05 measures heat flux from conduction, radiation and convection. Optionally, black (BLK) and gold (GLD) stickers are available for all five models to separately determine heat transport by radiation and convection.

Heat flux sensors that cover most heat flux measurement applications

Sensors of the FHF05 series are suitable for general-purpose heat flux measurement. The range is available in five different dimensions. Larger dimensions mean a higher sensitivity and a larger area over which the heat flux is averaged. They are thin, flexible and versatile. FHF05 measures heat flux through the object in which it is incorporated or on which it is mounted, in W/m2. The sensor in FHF05 is a thermopile. This thermopile measures the temperature difference across FHF05’s flexible body. A type T thermocouple is integrated as well. 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 its incorporated spreaders, the sensitivity of FHF05 is independent of its environment. Many competing sensors do not have thermal spreaders. The passive guard area around the sensor reduces measurement errors due to edge effects and is also used for mounting.
