Two self-calibrating foil heat flux sensors with thermal spreaders and heater Introducing next-level sensors from the world market leader in heat flux measurement! FHF05SC sensors are a combination of our standard models FHF05 series heat flux sensors and an integrated heater. The heater allows you to perform self-tests, verifying sensor functionality and stability during use, without having to remove the sensor. Figure 1 Model FHF05SC-50X50 and FHF05SC-85X85 self-calibrating heat flux sensor with heater: thin, flexible, and versatile. FHF05SC series is ideal for high-accuracy and long-term heat...

Introduction FHF05SC self-calibrating sensors consist of a heat flux sensor, combined with a heater. This combination is used when the highest level of quality assurance is required and for long-term heat flux measurements. their environment. Many competing sensors do not have thermal spreaders, so their sensitivity cannot be relied upon since it varies depending on the material on which they are mounted. The thin, flexible, and versatile FHF05SC sensors measure heat flux (in W/m2) either through the object in which they are incorporated or on which they are mounted. Each sensor contains a thermopile...

- heater for self-testing purposes - flexible (bending radius £ 15 x 10-3 m) - wide temperature range - fast response time - integrated Type T thermocouple - robust design, including cable connection block for strain relief (essential for outdoor and humid environments) - integrated thermal spreaders for low thermal conductivity dependence Using an FHF05SC sensor is easy. For heat flux measurements, it connects directly to commonly used data logging systems. The heat flux (in W/m2) is calculated by dividing the sensor output, a small voltage, by the sensitivity—which is provided on the sensor's...

Application example –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 The FHF05SC heater can be used to check for stable performance of the sensor at regular intervals without the need to uninstall the sensor or interrupt operation. A typical stability check is based on analysis of the step response of the measured heat flux and sensor temperature to several minutes of heating....

Hukx helps take your measurement to the next level: order FHF05SC with radiation-absorbing black and radiation-reflecting gold stickers. You can then use one sensor to measure convective + radiative flux and the other to measure convective flux only. Subtract the two measurements to obtain radiative flux. Options – with 5 or 10 m cable lengths – separate cable in 2, 5, or 10 m lengths – LI19 hand-held read-out...
