More than ever in the context of the current pandemic, glass tubes are vital for our health as a component of pharmaceutical packaging.
‘Simple’ glass tubes are turned into vitals, ampoules, and syringes to transport and inject vaccines under the best possible conditions. The raw material, glass, has to be inspected very carefully to check for any quality issues, such as airlines, inclusion, cracks, impurities, scratches, particles, roller marks, etc.
Besides the main measuring application of wall thickness, the various stages of a production line that turns tubes into containers also need to take predetermined dimensions into account, such as the diameter of the tube section. Non-contact 3D sensors from Precitec offer many advantages over other measurement methods for wall thickness inspection. The round shape of the sample requires a measurement system that is absolutely perpendicular to the top of the tube.
The infrared interferometry technology embedded in the Precitec CHRocodile 2 IT sensors makes this possible, and there is no equivalent solution for this application. The Precitec inspection system can measure at 70kHz in a thickness range from 4 µm to 12.6 mm and with nanometric resolution.
Some innovative options are available to optimize integration into a production line, e.g. having several points (multi-channels) in the same electronic controller. As a result of these numerous advantages, key players in this field have selected Precitec CHR 2 IT sensors as a unique solution for the in-line inspection of glass tubes.
