Hukseflux FHF02SC Heat Flux Sensor

A next-level sensor from the world market leader in heat flux measurement, FHF02SC is a combination of our model FHF02 heat flux sensor and a heater. The heater allows the user to perform self-tests, verifying sensor functionality and stability, during use, without having to remove the sensor. FHF02SC is ideal for high-accuracy and long-term heat flux measurement, construction of calorimeters, (zero heat flux) core temperature measurement and thermal conductivity test equipment.

Suggested use

  • high-accuracy scientific measurement of heat flux, with a high level of data quality assurance
  • study of convective heat transfer mechanisms
  • calorimeter prototyping
  • (zero heat flux) non-invasive core temperature measurement
  • thermal conductivity test equipment

A Next-Level Sensor for General-Purpose Heat Flux Measurement

FHF02SC is a sensor for general-purpose heat flux measurement, combined with a heater. It is used when the highest level of quality assurance is required and for special experiments. The FHF02SC thermopile sensor measures heat flux (W/m²) through the object in which it is incorporated or on which it is mounted. Additionally the integrated type T thermocouple allows for temperature measurements. Both the thermopile and thermocouple are passive sensors; they do not require power. The combination of a heat flux sensor with a heater allows the user not only to measure a heat flux, but also to apply a heat flux.

Using FHF02SC is easy

Using FHF02SC’s heat flux sensor is easy. It can be connected directly to commonly used data logging systems. The heat flux sensor output is a voltage signal that is proportional to the heat flux through the sensor: the heat flux in W/m² is calculated by dividing the sensor output, a small voltage, by the sensitivity. The sensitivity is provided with FHF02SC on its product certificate.
