Accurate heat transfer measurement is essential for modern building science and sustainable engineering. Architects and engineers need data that reflects real-world performance. However, traditional sensors often interfere with the system they measure.
The EKO HF-10S and HF-30S thin plate heat flux sensors solve this problem. These sensors have ultra-thin profiles and low thermal resistance. Consequently, they capture dynamic changes in heat flux with high accuracy and minimal disturbance.
Why “Thin” Matters: Eliminating Measurement Gaps
In thermal analysis, sensor thickness is often a major limitation. Thick sensors create gaps between surfaces. These gaps skew your data because they disturb the very layers you need to measure.
EKO’s thin-plate design provides several key advantages:
-
Seamless integration: You can place them directly between insulation layers without creating air pockets.
-
Precise quantification: These sensors help you quantify exactly how much heat moves through specific materials.
-
Better construction: This scientific approach allows you to fine-tune insulation materials for better energy efficiency.
Scaling Up: The Power of Large-Area Sensing

Measuring large surfaces with varying heat levels is often difficult. Therefore, EKO developed the HF-30S. This sensor features a massive 30×30 cm² measurement area.
This large surface area helps in several ways:
-
Averaging Heat Flux: The sensor calculates the average heat flux across its entire surface. This gives you a better macroscopic view of thermal behavior.
-
Improved Heating Design: Engineers use these sensors in floor assemblies to track heat distribution and dissipation.
-
Gradient Analysis: The substantial size helps you understand efficiency across a whole surface. As a result, you can adjust design parameters for better thermal equilibrium.
From Research to Reality
These sensors are also vital in laboratory settings. For example, you can integrate them into standard Heat Flow Meter (HFM) Apparatus. This helps you estimate thermal resistance and thermal conductivity more effectively.
In conclusion, the HF series empowers professionals to make informed decisions. By utilizing precise data, you can optimize system performance and meet global energy goals.
