1. What is a heat flux sensor?
A heat flux sensor is a sensor with a built-in thermopile that measures the rate of heat transfer per unit area, expressed in W/m².
2. How does a heat flux sensor work?
HF-01S uses a thermopile structure embedded in a thin plate to sense the temperature gradient across the sensor, which generates a small voltage.
3. What are common applications of heat flux sensor plates?
They are used in building physics, glazing monitoring, insulation testing, energy efficiency studies, Solar panel monitoring, material testing, biomedical research, and industrial process monitoring. See few application examples in downloads section.
4. What is the typical heat flux measurement range?
Ranges highly depend on the application, but most sensors can measure from a few W/m² up to ten kW/m². In buildings for instance, walls transfer in the range of around 1-10 W/m².
5. Do heat flux sensors require calibration?
Each sensor goes through calibration process and is calibrated against a reference standard to ensure reliable measurements. At EKO, we follow ISO and ASTM standards for this purpose. The sensor comes with a calibration certificate, where calibration conditions and the test results are officially declared.
6. How do I install a heat flux sensor plate?
They are usually embedded in material or mounted directly onto the surface where heat transfer needs to be measured, using adhesives, thermal paste, for good thermal contact. See the Installation Video to learn the best practices.
7. What environmental conditions can HF-01S withstand?
HF-01S can operate within –30 °C to +100 °C. The sensor is waterproof IP67 and can be used outdoors. Please note that the cable has a different temperature condition. When attaching the sensor on +100 °C, please do not attach the cable to that surface.
8. How do I interpret the output signal?
The sensor provides a voltage (µV to mV range) proportional to heat flux level, which can be read by a data acquisition system. Divide the voltage by the sensitivity value provided on the senso’s tag or the calibration certificate to convert the voltage into heat flux (W/m²).
