Economical measurement with computed tomography

As a pioneer in the integration of computed tomography into coordinate metrology, Werth revolutionized the industry in 2005 with the first TomoScope® CT machine developed for coordinate metrology. The benefit was the complete capture of the workpiece using X-ray technology for accurate, fast and economical measurements.

Over the run-out of the years, Werth developed several new device concepts and components. On its 20th anniversary, four TomoScope® device series with different sizes have established themselves in quality assurance around the world. With the evolution of CT technology, the use of computed tomography is now an economical solution for a wide range of measurement tasks. Werth initially responded to the wishes of many users according to the availability of the benefits of the small TomoScope® XS machines for larger workpieces with the TomoScope® XS Plus. In 2023, the TomoScope® S Plus was introduced with a particularly large measuring range in a compact format. To meet the requirements for the measurement of workpieces made of denser materials or with longer radiographic lengths in compact machines, Werth presented further new models in the successful TomoScope® XS and TomoScope® S machine series in 2025. The standard-compliant specifications of the length measurement error MPE for E: (4 + L/75) µm and the distance error MPE for SD: (2.5 + L/100) µm demonstrate what is certainly the highest accuracy in these machine classes.

Economical coordinate metrology with computed tomography

The TomoScope® XS series is characterized by its special feature of cost-effectiveness in use. With innovative X-ray technology, the TomoScope® XS machines enable 5 times faster measurements compared to conventional CT measuring systems, with high availability and low costs. Despite their compact design, the machines have a large measuring range. Measurements with a structural resolution of just a few micrometers are possible. Standard-compliant calibration, optionally with a DAkkS certificate, guarantees the performance of the machines. Calibrated calibration standards are used to ensure the traceability of all measurement results.

Increased performance for TomoScope® XS device series

The new TomoScope® XS Plus 230 has probably the most powerful transmission source on the market with up to 140 W. This enables even shorter measurement times compared to transmission sources with 80 W, for example. One application example is the measurement of prismatic battery cells in the automotive or e-bike industry. The high voltage of up to 230 kV also makes it possible to penetrate workpieces with a higher density, such as steel implants for shoulders or jaws. The compact device size, similar to the TomoScope® XS Plus 200, is ideal for installation on the shop floor. As with the other TomoScope® XS devices, the Werth long-life transmission sources ensure high availability and lower maintenance costs compared to machines with conventional sources.

Economically measure larger workpieces with the TomoScope® S Plus 230

The new 230 kV transmission source is also available for larger measuring ranges with the new TomoScope® S Plus. The machines have a particularly large measuring volume (up to D = 500 mm and L = 650 mm) compared to their compact external dimensions. With the high power of up to 140 watts, car headlights, for example, can now be completely measured even faster. The low-maintenance operation familiar from the XS devices is also possible for this machine class.
