How it works
Heat Flux Sensor: The Standard for Thermal Analysis
EKO’s Heat Flux Sensors accurately measure thermal energy flow for critical applications like Building Physics (ISO 9869 compliance) and R&D . The core HF-01S sensor is small highly sensitive, and features low thermal resistance to minimize interference, ensuring reliable data for evaluating insulation performance and heat transfer rates.
Standard Heat Flux Sensor
The HF-01S is a small size standard plate type heat flux sensor. It is an ideal option for research and engineering applications as well as manufacturing control and monito-ring processes. Manufactured in compliance with standards ASTM C1046 and ISO 9869, EKO HF-01S includes a built-in thermal guard and two facings to ensure an even heat flux distribution and therefore a reliable measurement experience.
Thinnest plate sensor
The HF-10S, at only 0.5mm thick, is a super-thin option for applications where the sensor’s thermal resistance must be minimal, ideal for a variety of research applications and manufacturing control processes.
Extra Large 30 x 30 cm²
Weather-proofed, ultra-thin, and extra big. The HF-30S is perfect for measuring average heat flux over a large, flat area or surface.
Heat Flux Sensor Extension Package
Extend heat flux sensor cable with EKO Extension package to measure heat flux with high accuracy and precision on 20 meters away. Low resistance and high quality cables.
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).
