The multi-sensor CFZ combines a telecentric 10x zoom optic with a powerful distance sensor in one beam path (patent).

High-performance sensors make it possible to dispense with mechanical device axes and create a low-cost machine with X-ray computed tomography for use close to and integrated into production.

The advantages of the TomoScope® XS, low measuring time, high resolution and low operating costs, are now also available for larger workpieces with a smaller device size.

The Werth TomoScope® FQ machines have a greatly increased measuring speed as well as a new evaluation concept and are therefore also suitable for integration into production lines.

A new logistics centre is put into operation, which takes into account the increased requirements for the dispatch of the high-precision measuring machines of the TomoScope®, VideoCheck® and ScopeCheck® series. The space thus gained is urgently needed for the production of the TomoScope® XS machines.

With two or three separate sensor axes, the multi-sensor systems can now be used even more flexibly. Mutual restriction in the use of sensors is a thing of the past.

With the foundation of Werth Messtechnik Austria, an important step is taken to further optimise customer support. The subsidiary takes care of all concerns in the Departments of Sales, Service and Application. Today, Werth Messtechnik Austria has a demonstration centre in Vienna.

This compact and inexpensive TomoScope® offers the advantages of proven technology in XS format. The X-Ray tube in monoblock design with transmission target combines approximately five times faster measurement compared to conventional systems with low maintenance costs.

The number of employees, which has risen to about 300, and the continuously increasing turnover are taken into account by another new building. All offices and machine assembly halls are now air-conditioned as well.

During the movement of the device axes, many images of the measuring object are taken and assembled into one large overall image with the highest resolution (patent). Then, for example, the ToleranceFit® software can be used to compare the entire object to the CAD or to determine the geometrical characteristics.

Werth Italia S.r.l., conveniently located in the south of Milan, now directly provides support and service for the Italian market. The team on location is a competent contact for all questions regarding Werth products and services.
