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 |

BLK – GLD sticker series has unique features and benefits:

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 and radiative heat flux has never been easier. |

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. The image shows FHF05 heat flux sensor with BLK-5050 black and GLD-5050 gold sticker. |
