Werth ScopeCheck® FB DZ – Multisensor Technology Now Even More Flexible

With two independent sensor axes, the ScopeCheck® FB DZ enables multisensor measurements without restrictions. After disassembly of glass table and transmitted light unit, heavy workpieces can now be mounted and measured directly on the measurement table.
The Werth ScopeCheck® FB DZ product line offers compact devices with large measuring ranges. A large combined measurement range can be achieved for Multisensor measurements, as for the smallest machine it is 425 mm x 500 mm x 350 mm with an image processing sensor and a conventional probe. For measurements with only one sensor, the smallest machine offers an expanded measuring range of up to 530 mm x 500 mm x 350 mm. Larger measuring ranges are for example 1130 mm x 650 mm x 350 mm in size. The new ScopeCheck® FB DZ is compact with low weight. The machine is sturdy, with good ambient vibration responsiveness.
The ScopeCheck® FB can be loaded from all four sides, and the accessibility is improved even more with the extendable measuring table. With the new transmitted light concept, the glass table and transmitted light unit are easy to disassemble for the measurement of heavy workpieces, and the workpieces can be mounted directly on the measurement table.
Two Sensor Axes In Place Of Two Coordinate Measuring Devices
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 workpiece 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 workpiece. 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 workpieces.
Multisensor Technology for Any Type of Application
The basic ScopeCheck® FB DZ configuration includes the proven zoom optics. Optionally, the machine can be equipped with the patented Werth Zoom. The Werth Zoom not only allows the user the choice of magnification, but the working distance can also be adjusted to achieve collision-free measurements in deep holes or of cylindrical workpieces with large diameters. With the MultiRing®, different light angles of incidence can be set, for instance, to optimize the contrast of flat edges with a short working distance and an extremely small angle.
The entire spectrum of modern multisensor technology can be used with the ScopeCheck® FB DZ. The laser distance sensor, Werth Laser Probe (WLP), is integrated into the beam path of the image processing sensor. The Laser Line Probe (LLP) can be used with a rotary/tilt head to be able to measure large workpieces from all sides. The patented Werth Fiber Probe® (WFP) and Werth Contour Probe (WCP) tactile-optical sensors can also be used with the ScopeCheck® FB DZ. The WCP enables standard-compliant roughness measurements in workpiece coordinates without a preferred direction. The patented micro-probe WFP®, equipped with a small probe sphere (diameter down to 20 µm) and flexible shaft, achieves probing forces that are up to 100 times smaller than for conventional tactile-electrical probes. These properties make the Microprobe WFP® well suited for 3D measurements of micro-geometries and sensitive surfaces.
