Knowledge- & Test centre

Goudsmit places great importance on reliability; our magnetic systems meet the promised specifications. We have been developing and selling magnetic systems since 1959, so we have a wealth of knowledge and experience to draw upon. To provide exact specifications and guarantees, we heed the motto: to measure is to know! Some of the many ways we collect the required data include:

Magnetic measurements on basic magnets

The following are some examples of measuring devices we use to capture all data the that are relevant for us and our customers. The result is greater and more rapid insight into the characteristics and behaviour of a product in a certain environment or assembly.



3D coordinate measurement machine

Goudsmit 3D Magnet measurement

We use a 3D coordinate measuring machine (CMM) to perform 3D measurements on magnets and non-magnetic materials with the aid of a scanning sensor.


Magnetization bench

Magnetization bench

Using our magnetization unit we can magnetize unmagnetized magnets to full saturation. This is, however, limited to the maximum dimensions of our coils and the desired shape of the magnetic field.

Handheld XRF analyser

Element checker

Non-destructive material analysis based on X-ray technology.

Roughness tester

Roughness tester

To check whether magnets/assemblies meet the roughness requirements.


Other measuring equipment

  • manual and fully automatic CMM machines;
  • layer thickness and hardness meters;
  • screw thread measurements;
  • shadow image projection and microscopes for optical inspections;
  • mass spectrometers for checking composition.

Test centre Recycling / Handling / Separation

Why a test centre?

Find the best solution for your problem: in the updated test centre we conduct tests on both our own products and yours to determine which system would be most suitable. We are happy to work with you to develop custom magnetic systems.

For optimization of our product range: all the test results from the test centre are fed into a database which now contains many years' worth of valuable, real world information. This database is growing by the day and serves as an important source of input for product optimization of our magnetic systems. This knowledge enables us to develop more precisely what is needed and provide you with more detailed advice.


Which product groups are tested?


test center recycling
In the interest of serving the recycling industry, the test centre includes our entire range of recycling machines. Here, for example, you will find not only our Eddy Current separators and vibratory chutes but also robust magnetic separators and drum magnets, head rollers and overbelt conveyors, and combinations thereof. It is therefore possible to process bulk samples of all your materials, from coarse to very fine.



filter SSFM in use
In our test centre we test all our magnetic separators for separation yields, flow optimization and cleanability as well as for service life and ease of use. Send us a sample of your product and we will investigate how much iron contamination it contains and which magnetic separator is best for your situation.


Handling / lifting

Our test centre contains all the equipment necessary for testing our magnetic handling systems. This includes performing durability tests (service life) and measuring the force exerted by our lifting magnets in all sorts of situations.

Many factors must be considered when it comes to the quick, safe magnetic handling/lifting of products. In order to leave nothing to chance, we can simulate many situations in our test centre to ensure that the magnetic systems we develop are safe.

Conveyor systems

Our magnetic conveyor systems are almost always made to order. To develop the most optimal system for you, we have every possible magnetic and conveyor component available in our test centre so we can put together a test setup. This enables us to simulate the magnetic operation of the systems so we can develop the most suitable conveyor system for your product.

3D Magnetic calculations

In addition to conducting measurements and tests, we have put years of investment into magnetic calculations. In the past our measurements were merely two dimensional, but for quite some time now we have had the capability to perform measurements in 3D.
As such, we can now develop the right magnetic system for you more quickly and with even better results. We are also happy to perform any calculations you may require. Just ask!

Magnetic calculations are a class apart in the world of stress calculations. Goudsmit has the right software, highly trained personnel and a huge wealth of experience. Therefore we can confidently say that you can entrust us with any engineering question.
