The WIP is a non-contact fibre optic sensor for highly accurate measurement of geometry, mould and roughness. Probe geometries can be individually adapted with regard to the necessary exit angles for probing the workpiece surfaces. Due to the small probe dimensions, the WIP is particularly suitable for capturing small, difficult to access and deep geometries and is thus part of Werth's special expertise in the measurement of micro-geometries as well.

In RS version, the WIP allows highly accurate roundness measurement with rotatable probe

Due to the guideway of the fibre in a metal tube, the probes can also be offered in very long lengths for large probing depths

The grinding of the probe determines the exit angle of the measuring beam between 0° and 90°, probes with a 90° angle are used, for example, for measuring the lateral surfaces of small bores

Sensor principle

Optical (short-coherent interferometry)

Measuring range

300 µm

Accuracy

Permissible probing error up to 0.2 µm

Functionality

With a superluminescent diode a) and a measuring probe c) connected via a fibre coupler b), the information about the time difference of the light reflected at the probe exit surface d) and the workpiece surface e) is measured. c) and the workpiece surface e) is projected by the interferometer (imaging optics f), beam splitter g), mirrors h) and i) and cylindrical lens j)) onto a line camera k) and the distance is determined from this.
