The machine can optionally be equipped with two independent sensor axes. Both optical and tactile measurements as well as an optimal combination of both measurement principles are possible. During measurements with one sensor, the second axis remains in the park position outside of the measuring range. This ensures that the geometries of the work piece can be accessed from all sides without the risk of collision. In combination with the thin probing ram, this allows for lowering of the sensor into a large work piece. If the machine is only equipped with one sensor axis, the second axis can be added later onsite if found to be necessary. With the Werth Multisensor System, a wide variety of sensors can be attached to each sensor axis. These sensors are attached with a magnet coupling without offsetting the sensors at the same position in front of the beam path of the image processing sensor. To be able to automatically set up different sensors, the retracting axis for changing racks is now also available for the ScopeCheck FB DZ. The changing rack is only moved from its park position into the measuring range via the coordinate measuring machine axes when the sensors are being changed. After the change it returns to its park position outside of the measuring range. The benefit here is that the entire measurement range may be used to measure work pieces.
