Steel Cord Belt Scanning

We can not usually tell what is happening inside a steel cord reinforced conveyor belt by inspecting the surface.

Sometimes rather common looking cover cracks and cuts are deep enough to allow moisture into the cords. If this happens, corrosion will begin.

Also, the low stretch characteristics of steel cords that we like, also make them easy to break due to common conditions such as trapped material, ice or material buildup on pulleys or worn lagging.

What is Condition Monitoring

A condition evaluation of your critical steel cord conveyor belting is performed by mounting a non-contact, non-destructive instrument across the width of the belt.

While the belt is running, it aligns the magnetic fields of the steel cord belt. Any imperfections or changes in the steel cords, will cause changes to the magnetic field. These disturbances, when recorded indicate the presence of cord breaks, cord damage or corrosion. Computer advances allow signal processing techniques to be used which enhances the quality of the information obtained over traditional methods.

How Does it Work?

1. Magnetize the steel cords.

2. Measure the emf generated by the changing magnetic field at cord ends, breaks or damage areas.

3. Convert the emf signal to a binary form.

4. Analyze the data with a computer to locate and interpret the changes in the belt over time.
