HF-10S Heat flux sensor

  • Thin heatflux sensor
  • Low thermal resistance
  • Small size
  • Weather proof
  • Calibration complies with JIS A 1412

The HF-10S measures heat flux through an object it is mounted to, in W/m2. The HF-10S features a very thin design and has a low thermal resistance. Heat flux sensors can be used in a variety of research applications and manufacturing control processes. EKO has various types of thin substrate heat flux sensors in the product line-up.

A heat flux sensor is a thermopile sensor which generates an electric signal proportional to the temperature difference (ΔT) across the thermocouple hot and cold junctions. To generate a measurable voltage, heat flux sensors have multiple thermocouples spread over the total area connected in series. EKO heat flux sensors are available in different sizes and thickness.
