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.

Laser Scanner Solution: This task is a typical application of the high-resolution QuellTech 2D/3D Q5-880 Blue Laser Scanners. Two of these units are placed at the left and at the right of the measuring objects, at a defined inclination angle. Blue laser light in this case is a prerequisite, as the cast parts are red-hot, hence emitting in the red spectral range. Additionally, the client was in need of a software solution for the project, so a 3D point cloud processing application was implemented, performing inline and evaluating width, height and angle results. QuellTech customer is able to inspect continuously the product quality, simultaneously avoiding scrap. He uses the same system for more than 10 different types of castings. Errors caused by manual inspection are considerably reduced, and safety for personnel is enhanced.

Particular Challenge: For the assessment of rotating parts, numerous parameters have to be taken into consideration: Concentricity, radial run-out and axial run-out (i.e. wobble); furthermore thickness, diameter, planarity and the absence of surface defects had to be examined. The solution developed by QuellTech consists in a configuration of three Q6 Laser Laser Scanners.Each of the lateral surfaces is assigned to its own scanner. In order to enable the thickness precisely to be determined, both laser lines are mutually oriented in opposite direction. The third scanner inspects the outer circumference of the wheel, this way measuring diameter and radial run-out. All of these scanners are subject to encoder signals supplied by the rotary axis and synchronously triggered, so possible defects on the wheel can precisely be localized. The measurement takes place at a resolution of ca. 30 µm, and a cloud comprising several millions of points are obtained.

eddyMOTION is a Windows-based analysis and configuration tool for eddy current probes. In combination with the TX electronics from eddylab GmbH, the software tool combines several performance features: The functional areas oscilloscope, FFT analysis, data logger and waterfall diagram, enables the visualization and documentation of mechanical movements. eddyMOTION also suites the on-site linearization of eddy current sensors in a traceable manner, without external assistance. In addition to the TX electronics and an eddylab eddy current sensor, a reference probe is required for this purpose: Together with the eddy current sensor, this probe measures the distance to the same material, with the reference probe serving to check the sensor.

Temperature is one of the most measured physical parameters. Despite this, precise temperature measurement is one of the most difficult tasks in motor technology. To meet the constantly increasing requirements for improved motor performance, higher efficiency and reduced emissions, it is necessary to use reliable and precise sensors in modern motor control systems. The increased requirements over the last few years regarding measurement accuracy and reliability of temperature measurements has meant that many equipment operators must reconsider the suitability and performance capacity of their temperature measurement equipment. Resistant thermometers can be used between -200 °C and +850 °C. An important common property is that their output parameters are available in the form of electric signals that can be relatively easily transferred to measurement and control instruments for processing, storage and display.
