BLK – GLD sticker series

Black and gold stickers for measuring convective and radiative heat flux separately
Want to study energy transport / heat flux in detail? Hukseflux helps taking your measurement to the next level. Simply provide your heat flux sensors with radiation-absorbing black and radiation-reflecting gold stickers. You can then measure convective + radiative flux with one, and only convective flux with the other. Subtract the two measurements and you have radiative flux. BLK and GLD stickers are available for sensor models FHF05 series and HFP01. They are designed to be applied by the user to the sensor; see the user manual and installation video for instructions. The black and gold stickers allow the calculation and measurement of convective + radiative flux with one, and only convective flux with the other. Subtract the two measurements and you have radiative flux. BLK and GLD stickers are available for sensor models FHF05 series and HFP01. They are designed to be applied by the user to the sensor; see the user manual and installation video for instructions. Heat flux measurement is a powerful tool to gain insights into processes involving thermal energy. Heat flux consists of conductive, convective and radiative flux. Measuring heat flux, users may wish to measure only radiative or only convective heat flux. This is now possible with the BLK – GLD sticker series, designed to be used with a wide range of our market-leading heat flux sensors. The BLK black absorbing stickers will absorb all radiation and are sensitive to both radiative and convective heat flux, while the GLD gold reflective stickers reflect all radiation and are sensitive to convective heat flux only. Combining BLK and GLD, applied to two separate heat flux sensors, will allow for measuring radiative heat flux: Φ radiation + convection = Φ BLK Φ convection = Φ GLD Φ radiation = Φ BLK – Φ GLD

SKU: BLK - GLD Category: Brand:

BLK – GLD stickers are designed to be applied by the user, but can optionally also be pre-applied at the factory. Applying a sticker to a heat flux sensor does not change the sensitivity of the sensor, so no additional calibration is required. Using the reliable measurement technology behind our heat flux sensors, separating convective.

The working principle of BLK – GLD stickers: sensors equipped with black absorbing stickers will absorb all radiation while gold reflective stickers reflect all radiation. Both stickers are sensitive to convective heat flux. and radiative heat flux has never been easier.
