| Measurement of the radial deviation of a cutter disk |
 |
The thickness of veneer strips from laminated wood must be less than 1 mm and may only exhibit tolerances in the micrometer range. Thicker parts or splinters reduce the quality of the veneer strips. The quality of wood plate materials is determined by the quality of the chips or veneer strips. The latter depends to a high degree on the precision of the cutting disk and the associated tolerances (cast body, blade holder, slicing blade) under production conditions and loads. To maintain the quality criteria the radial deviation of the cutting disk is measured and monitored during the production process with a non-contact laser triangulation sensor.

| Measurement of the radial deviation on superconducting magnets |
 |
Motors with superconducting permanent magnetic bearings using high temperature superconductors are applied for feed pumps for liquid nitrogen. For the measurement of the radial deviation of these magnetic bearings, U1 eddy current sensors with special temperature compensation for -196 °C and 20 °C are used in the evacuated and cooled ambient.

| Active damping of liquid-cooled centrifuges |
 |
At certain configurations of speed, filling level and design parameters, liquid-filled industrial centrifuges tend to produce unstable running characteristics which can lead to failure of the centrifuge. The instability, which arises due to interaction between the fluid and the centrifuge, cannot be rectified by passive means (dampers), so therefore the instability is corrected actively with the aid of a magnetic bearing and suitable closed-loop controllers. The deflection of the rotor, which is acquired with two eddy-current sensors orientated at 90° to one another, is used as input information for the controller.

| Non-contacting roundness measurement for rollers |
 |
In the production of tapes and foils the high speeds of up to 2700 m/min that are used today lead to an increased vibration tendency in the roller stands. Even smallest µm-range irregularities in the rolling contour lead to cross-grooves on the rolled material and thus clearly reduce the quality of the product. For quality assurance a high-precision roundness measuring system for rollers is required, in which an eddy-current sensor measures the surface contour of the roller.
