General purpose bipolar range transmitters that are designed to be used with the HukseFlux HFP01 heat flux plate. The GS42H has two inputs and the GS44H has four inputs; all inputs have the same range. This range is hardware configured at the time of manufacture. The transmitter will have a suffix letter corresponding to the range - see the specification section for more details.
HFP01 heat flux sensor is frequently specified for building performance monitoring studies, that is through walls and building envelopes. The total thermal resistance is kept small by using a ceramics-plastic composite body. The sensor is very robust and stable. It is suitable for long term use on one location as well as repeated installation when a measuring system is used at multiple locations.
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. 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.
This kit enables fitment of the transmitter's built-in wall bracket to difficult or uneven surfaces. The kit provides additional docking security.
