For quality control, the surface roughness of a test item is to be tested and its contour recorded.

The installation consists of four surface roughness gauges which are connected via four serial interfaces (RS232), a laser micrometer and a glass scale.

For the acquisition, the compact real-time PAC system MSX-Box is used, which includes PC boards with the following functions: counter, analog I/O, serial interfaces. In this case, the version of the MSX-box with PCI backplane is used.

For extremely harsh environments, it is also possible to use the compact PCI version with the corresponding CompactPCI boards.
