You have been producing devices for measuring
surface condition for many years. What has changed since then, with regard to
the requirements for these special measuring devices?
Martial Wüthrich: Above all, the evaluation electronics have been improved. Thanks to various features, the measurement results are displayed faster, more accurate and are more user friendly. Of course, the standards have also changed during this time and the scanning of the surface had to be adapted accordingly. The roughness of the surface can be measured optically or by touch.
Diavite AG concentrates on the production of tactile measuring instruments. Why?
The costs of the two systems are very different. Although optical measurement does not give better results in everyday life, optical measuring instruments are about three times more expensive than tactile ones. Tactile measuring is simpler, equivalent in terms of results, less susceptible to corrupted data, and also cheaper. It is clear that far more tactile measuring devices are in use than optical systems.
Are there fundamental differences within the family of probing instruments for measuring surface roughness?
In tactile measurement, we distinguish between two measurement methods. For portable measuring devices, we use mostly skid probes. The runner on the probe forms the reference against which the diamond measures. A mechanical filter is, therefore, used. The second measuring method is the version with a free stylus, i.e. the measurement with an external reference. In this case, only a tripod can be used, since the guide in the feed forms the reference for the diamond. With this method it is possible to measure not only the roughness, but also the contour and profile.
