Thermal Sensors FHF05 series - heat flux sensors Five models covering the most common heat flux measurement applications; new, patented technology, flexible, with temperature sensor FHF05 is the product range to start your search if you consider measuring heat flux. Models are available in five different dimensions and sensitivities. All models from the FHF05 series 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 sensors measure 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. In case the FHF05 series does not match your needs, have a look at our other heat flux sensor models for special applications. Figure 1 FHF05 series foil heat flux sensors with thermal spreaders: thin, flexible and versatile. Models are available in five different dimensions and sensitivities. FHF05 series: covers 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 series models measure heat flux through the object in which they are incorporated or on which they are 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 to provide a measurement of temperature. The thermopile and thermocouple are passive sensors; they do not require power. Copyright by Hukseflux. Version 2205. We reserve the right to change specifications without prior notice Page 1/6.

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 the FHF05 series is independent of its environment. Many competing sensors do not have thermal spreaders. The passive guard area around the...

Thermal Sensors Figure 3 FHF05-15X85, thin and flexible, can be easily mounted on a curved surface like a pipe or tube. Robust and stable Equipped with a connection block, which may serve as strain relief, with potted protective covers on both sides which prevent moisture from penetrating, FHF05 has proven to be very robust and stable. Figure 5 FHF05-15X30 or -15X85 heat flux sensor: (1) sensing area with thermal spreaders, (2) passive guard, (3) type T thermocouple, (4) dot indicating front side, (5) connection block, (6) cable, standard length is 2 m.

Thermal Sensors Optionally, they can be ordered pre-applied. See the BLK – GLD sticker series user manual and installation video for instructions. Suggested use FHF05 series can be used for general-purpose heat flux measurement, often applied as part of a larger test- or measuring system. FHF05SC series on the other hand, are self-calibrating versions of the standard FHF05 models, combined with a HTR02 series heater. FHF05SC series is used when the highest level of quality assurance is required and for long-term heat flux measurement. The self-calibrating sensor is available in models...

Thermal Sensors Select your model FHF05 is available in 5 different sizes. The following text helps you to select the right sensor for your application and electronics. Selecting the right electronics - sensor combination helps reducing total system costs. Step 1 Visit the Hukseflux YouTube channel: • quick intro to heat flux (3 min); • online course (40 min); • separating radiation and convection (2 min). Step 2 Verify that FHF05 series is suitable for your situation/heat flux problem/application: • the heat flux is between -10 to +10 x 103 W/m2; • the rated temperature range is below 120...

Thermal Sensors MARKET LEADER IN HEAT FLUX MEASUREMENT FHF05 series outperforms competing models: how? FHF05 series are Hukseflux’ standard models for thin, flexible and versatile heat flux sensors. Flexible FHF05 series is extremely flexible and may be bent to a radius of 7.5 mm. Sensitive area with thermal spreaders reducing thermal conductivity dependence Unlike many competing sensors, FHF05 series sensors have thermal spreaders, i.e., conductive layers covering the sensor. These layers help reduce the thermal conductivity dependence of the measurement. By employing spreaders, the...
