Data Quality and Information Content
Data quality describes the suitability of measurement values to support valid decision-making processes. Information content goes a step further and refers to the portion of captured data that is actually relevant for evaluating the process state or product quality. In industrial inline measurement technology, data quality does not arise from the sensor alone, but from the interaction of measurement strategy, environmental conditions, and structured data evaluation.
Radius Measurement with Two Laser Scanners
Modern 2D and 3D measurement systems generate large volumes of data—for example image data or point clouds. Initially, these raw data sets contain only geometric or optical information. Only through targeted feature extraction and process-oriented interpretation do they become decision-relevant information.
• Geometric parameters (distances, heights, widths, gap dimensions)
• Form and position deviations
• Surface parameters
• Statistical trend values over time
The key requirement is that these features have a direct correlation with the functional or quality requirements of the component.
Data quality does not become evident in the laboratory, but under real operating conditions—including cycle time constraints, temperature variation, and mechanical influences. An inline system must therefore not only measure precisely, but also convert the acquired data into stable and reproducible process information.
QuellTech follows a structured project process (“Precision step by step”), in which measurement requirements, feature definition, and serial production integration are systematically aligned. The goal is not to generate the maximum amount of data, but to provide valid, process-relevant information for industrial quality decisions.
