The patented Werth Fiber Probe® WFP 2D has set the industry standard for micro-probes for decades and enables highly accurate tactile measurements of extremely small geometries with the smallest probing forces. Due to its low probing forces, the WFP® is also suitable for calibrating optical measurements on workpieces with sensitive surfaces. Typical areas of application are rubber and plastic parts, gauges, spinnerets, micro-gears and micro-bores on injection nozzles and turbine blades.

Due to the direct evaluation of the stylus tip, the WFP® achieves probing errors in the range of a few tenths of a micrometer

Bending of the stylus shaft has no influence on the measurement result

The resolution of the fiber probe is in the nanometer range and is ultimately only dependent on the optics used

In scanning mode, the Werth Stylus® records a wide range of contours with a large number of measurement points, whereby the stylus is permanently kept in motion by a vibration generator in order to avoid stick-slip effects

Sensor principle

Tactile-optical

Accuracy

Permissible probing error up to 0.3 µm

Functionality

An image processing sensor (a) camera, b) imaging optics) is used to measure the deflection ΔL of the stylus tip illuminated by an LED c) when the workpiece e) moves. In the target deflection, the exact position of the stylus tip is superimposed with the coordinates of the scale systems of the machine and stored as measurement points or used for the scanning process. Dual-sphere probes f) achieve a greater probing depth than single-sphere probes g).
