HF-30S Heat flux sensor

  • Thinnest heat flux sensor on the market
  • Large area sensor
  • Low thermal resistance
  • Weather proof

The HF-30S is a large area (300 x 300mm) fthin foil heat flow sensor. Due to its large sizes it gives properly averaged thermal conductivity results for large areas without the potential risk of measuring local hot spot effects or thermal bridges.

The low output Voltage of the heat flow sensor can be easily converted to a 4-20mA current or higher Voltage using the MS-4..20mA converter. The mV/mA converter can be pre-programmed and optimized within the operating range compatible with common measurement equipment.
