Siegfried Werth (* 1907 , † 1982 ) was a German measuring technology - developers and entrepreneurs .

Career

After studying mechanical engineering and graduating as a Dr.-Ing. At the Technical University of Berlin (today TU Berlin ) he founded the company Werth Apparate und Maschinen in 1951 . This company later became Werth Messtechnik GmbH. The company moved from Düsseldorf to Gießen in 1958 and is now one of the world market leaders in coordinate measuring technology with optical sensors, X-ray tomography and multi-sensor technology.

At the beginning of the 1950s, Siegfried Werth developed his first measuring devices - cone probes, Zetmeter and Panohol, which were used for measuring and testing drawing dies for wire production. In 1955 he designed the first profile projector in console construction, which was significantly lighter and more compact than conventional models in column construction. The optical beam path was integrated into the housing with the help of mirrors. As a result, the measuring devices also had improved ergonomics .

Optimus CC - fully automatic optical coordinate measuring machine (1980)

At the end of the 1970s, Siegfried Werth developed the first optical sensor for measuring projectors. The Werth probe eye is a point-shaped fiber sensor for use in the transmitted light method, i.e. on the shadow image of the workpiece. When the workpiece edge is passed, the edge position is automatically detected based on the light-dark transition. In connection with a CNC control, this sensor enabled the automation of optical measuring devices for the first time in 1980.

In 1987 the widow of the entrepreneur, Maria Werth, founded the Dr.-Ing. Siegfried Werth Foundation , which has since promoted scientific work in the field of contactless dimensional measurement technology.
