BLK - GLD sticker series

BLK - GLD sticker series, accessory for FHF04, FHF04SC, FHF03 and HFP01 heat flux sensors
 BLK – GLD sticker series allows users, measuring heat flux, to measure only radiative or only convective heat flux.
radiation-absorbing black and radiation-reflecting gold stickers for use with a range of sensors
Stickers available for FHF04, FHF04SC, FHF03 and HFP01 heat flux meters
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: provide your heat flux sensors with radiation-absorbing black and radiation-reflecting gold stickers. You can then measure convective + radiative flux with one, and convective flux only with the other. Subtract the two measurements and you have radiative flux. GLD and BLK stickers are available for sensor models FHF04, FHF04SC, FHF03 and HFP01. They are designed to be applied by the user to the sensor; see the user manual and installation video for instructions.

Description

 BLK – GLD sticker series allows users, measuring heat flux, to measure only radiative or only convective heat flux.

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

heat flux sensors with gold and black stickers to measure heat flux in detail

BLK – GLD sticker series has unique features and benefits:

 

  • makes it possible to perform convective and radiative heat flux measurements
  • available as accessory for FHF04, FHF04SC, FHF03 and HFP01 heat flux sensors
  • designed to be applied by the user (See also the instruction video on our YouTube channel)

 

Stickers available for FHF04, FHF04SC, FHF03 and HFP01 heat flux meters

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.

radiation-absorbing black and radiation-reflecting gold stickers for use with a range of sensors

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 FHF04 heat flux sensor with BLK-5050 black and GLD-5050 gold sticker.
