An in-line measurement system is a specialized technology used in manufacturing processes to perform real-time measurements of various parameters directly within the production line. This system typically consists of sensors, detectors, or probes integrated into the machinery or production equipment. It play a critical role in ensuring product quality, enhancing process efficiency.

As the product moves through the production line, the in-line measurement system collects data on key characteristics such as width, thickness, weight, color, or other quality-related attributes. The collected data is then analyzed and processed using software algorithms to assess product quality, identify deviations from specifications, and provide feedback for process control.
