The PHFS-01 heat flux sensor measures heat flux using a low cost differential temperature thermopile that has the additional benefit of also being able to measure temperature.
This heat flux sensor measures the flow of thermal energy moving due to the temperature difference between the upper and lower sensor surfaces. It is very thin, which means that it can be bent around curved surfaces such as pipes, and does little to disrupt the heat flux paths in the system being measured.
Applications for the measurement of heat flux include
The PHFS-01 heat flux sensor is made by placing many type-T thermocouples in
series on both sides of a thermally resistive layer which creates a thermopile.
Heat flux moving through the thermally resistive layer induces an output voltage
proportional to the heat flux flow. The measured voltage is then converted into
a heat flux measurement by using the scale factor provided on a supplied
calibration certificate. Because this heat flux sensor is measuring heat flow
through the sensor, it is particularly suitable for measurement of conductive
and convective heat flux. When painted black, it will also very effectively measure radiative heat flux.

The PHFS-01 is available in 3 versions. The standard product "PHFS-01" for measurement of conductive and convective heat flux, and a black painted heat flux sensor "PHFS-01 Blk" for measurement of conductive, convective and radiative heat flux. These two products are both calibrated in a conductive heat flux setup. For accurate radiative heat flux measurement, the black painted PHFS-01 may be ordered with additional radiative calibration "PHFS-01 Blk+Cal".
