HFP01-05 Heat flux plate

HFP01 is the world’s most popular sensor for heat flux measurement

HFP01 measures heat flux through the object in which it is incorporated or on which it is mounted, in W/m².
The sensor in HFP01 is a thermopile. This thermopile measures the temperature difference across the ceramics-plastic composite body of HFP01. A thermopile is a passive sensor; it does not require power. Using HFP01 is easy.
It can be connected directly to commonly used data logging systems.
The heat flux in W/m² is calculated by dividing the HFP01 output, a small voltage, by the sensitivity.
The sensitivity is provided with HFP01 on its calibration certificate.
A typical measurement location is equipped with 2 or more sensors.
HFP01 is the world’s most popular sensor for heat flux measurement in the soil as well as through walls and building envelopes.

Robust and very stable

The HFP01 is equipped with heavy-duty cabling, protective covers on both sides and potted so that moisture does not penetrate the sensor, HFP01 has proven to be very robust and stable.
It survives longterm installation in soils, as well as repeated installation when a measuring system such as TRSYS01 is used at multiple locations.
