Particular Challenges of the Application: By tactile equipment, determination of the deepest point on a rough metal surface is neither simple or precise. As a consequence, often either too much material is removed, or the surface is still covered with defects which have to be eliminated by a following milling cycle. The equipment is arranged in parallel, so that the complete width of the slabs is covered. The sensors are calibrated to a common coordinate system and mounted on a movable gantry. Before measurement, the slabs are fixed in place. The scanners mounted on the gantry are guided over the measuring object, driven by an electric motor. The point cloud recorded by the four scanners is consolidated in a PC by means of the QuellTech image processing software which calculates the difference between highest and lowest point of the corresponding surface and compensates for possible inclination of the slab (detrending).

The QuellTech laser sensor family Q4 or Q5 used for these tasks is generally mounted on an arm of a rotational axis, to scan along the complete 360° angle of the internal surface in a sequence of strips. The Q4 sensors can also be used to control the weld seam tracking itself for rapid setup and ease of use. Even during a project, the range and scope of the Q Series sensor demonstrates the advantages of a modular system to quickly adapt to project needs, where the smallest system has provided fast analysis of pipes as small as 105mm. The low power, with standard communication protocols, enable battery powered systems to transmit wireless data to other systems for review and cloud back up.

Web process control The Qualiscan QMS is a modular system for measuring, logging and controlling critical process parameters over the entire width of the product, including basis weight, coating weight, thickness, moisture etc.

Non-contact eddyNCDT 3300 eddy current displacement sensors are designed for use in factory automation, for machine monitoring, for quality control and quality assurance. More than 80 differentes sensors models are available.

The automatic leakage tester used to control the tightness of CO2 inert gas packaging allows even the smallest leaks - even in the micro range - to be detected.The package is tested by simply placing it in the vacuum chamber. The automatic test cycle starts when the lid is closed. The unit generates a user-defined vacuum during this process. After the vacuum is reached, the sensor is set to the "virtual" zero point. If the CO2 concentration rises during the measuring time that now begins and was previously selected by the user, this indicates that the packaging is leaking. The measured increase of the CO2 content in ppm gives information about the size of the not tightly sealed area. The sensor demonstrably detects even the smallest leaks up to approx. 10 µm. (µm is a micrometre and corresponds to 0.001 millimetres)

Quality assurance through internal quality control , the quality characteristics like Light transmittance clarity Minimum thickness of the individual plates / packages are ensured.
