HFP03 Ultra-Sensitive Heat Flux Plate
The HFP03 is an Ultra sensitive heat flux plate for measurement of small heat fluxes in the soil as well as through walls and building envelopes. The total thermal resistance is kept small by using a ceramics-plastic composite body. See also model HFP01: putting several HFP01 sensors electrically in series is an alternative for using HFP03.
Ultra sensitive sensor for measurement of small heat fluxes
HFP03 measures heat flux through the object in which it is incorporated or on which it is mounted, in W/m². HFP03 is specifically suitable for measurement of small flux levels, in the order of less than 1 W/m², for instance in geothermal applications. The sensor in HFP03 is a thermopile. This thermopile measures the temperature difference across the ceramics-plastic composite body of HFP03. A thermopile is a passive sensor; it does not require power. Using HFP03 is easy. It can be connected directly to commonly used data logging systems. The heat flux in W/m² is calculated by dividing the HFP03 output, a small voltage, by the sensitivity. The sensitivity is provided with HFP03 on its calibration certificate.
Suggested uses include measuring:
- extremely small heat fluxes
- geothermal heat flux
