One Tool To Detect Many Quality Parameters – Fiber Areal Weight

The SURAGUS sensors detect two main measured variables. The angle and the strength of the signal. The strength of the signal allows conclusions to be drawn about the amount of material in the direction under consideration. As shown in the picture, a higher amplitude means a higher surface weight and a lower amplitude means less surface weight. Through our sensors, they will not be able to determine the exact basis weight. Our sensors are calibrated to a target value and relate the measured material to the target value.

How well this works depends very much on the composition. If several layers point in the same direction this is challenging for the analysis. The concept works very well in this case, but due to the missing possibility to separate the layers, only the total weight per unit area can be displayed. This leads to the fact that no recommendations for action can be derived to bring the process to the target values. Contact us to evaluate the applicability in your application.



One Tool To Detect Many Quality Parameters – Fiber Orientation Monitoring

Fiber orientation is one of the most important properties of a carbon fiber component loaded in tension. The fiber orientation directly determines the load limit. This is why the correct angle of the bonded plies is so important.

SURAGUS sensors are adjusted and optimized for the angle to be detected. Each angle to be examined receives its own sensor. The distances between the individual sensors are calculated out to obtain a result that is accurate to the point.

Easy to Use Software

The software is easy to use and clearly displays the recorded values. A report can be created for each roll and can be handed over to the customer as proof of quality.

  • High usability
  • Intuitive design/handling
  • High speed measurement and display of results
  • Data archiving



Demo Measurement To Show Feasibility

To give you an idea of the performance of eddy current technology, we offer you a free demo measurement.

The process goes something like this:

  1. You contact our sales team and describe your application case
  2. We evaluate whether the eddy current technology is suitable for your application
  3. For highly innovative materials a non-disclosure agreement can be made in advance
  4. You send us your samples
  5. We measure your samples
  6. We contact you and discuss the measurement results together
