Abstract
Thickness measurement has been applied in many industrial applications for quality control and in-service verification. Capacitive thickness measurement is one of commonly used methods for evaluating product such as thin film, as available in the laboratory exercise for Bachelor Course “Messwerterfassung und Umformung” at FH Soest, Germany. With more industrial products whose thickness need to be accurately determined, more thickness sensor systems need to be added into the laboratory exercise. This thesis work is focused on selecting and evaluating the suitability, accuracy and precision of two other sensor systems, namely laser triangulation sensor and eddy current sensor. The laser triangulation sensor is used to determine the thickness of aluminum plates of around 2mm, whereas the eddy current sensor is used to determine the thickness of thin films of around 84µm. The overall system will consist of PC with LabView, DAQ NI-6008 USB, sensor systems, and different types of objects whose thickness needs to be determined accurately. The NI – 6008 USB will be used as the data acquisition system which will be connected to a PC where LabView is used for recording and analyzing the sensor values. The measurement of the laser sensor revealed that the aluminum plate is exactly 2.00 mm. The measurement of the eddy current sensor revealed that the thin film to be 84.70 µm with a ± 0.99µm deviation. The most accurate sensor is the laser sensor with sensitivity of 0.8mV/µm, follow by the capacitor sensor of 1mV/µm, and lastly is the eddy current sensor of 4.3mV/µm.
