Article Preview

In this paper, the main new point is the use of a non-contact combinational system with a capacitive sensor and eddy current sensors to acquire measurement signals and the use of LabVIEW software platform for real time data processing of plastic film thickness. Using a combinational measurement system to replace a traditional micrometer, the thickness of plastic film can be measured intelligently, real time, and in non-contact mode with high precision. The whole system consists of a test unit, a data acquisition unit, a motor driving unit, and a data processing unit. The test unit does measurement by means of capacitive sensor and eddy current sensors. The system is operated on the LabVIEW software platform for automatic control of the whole process. The measurement process is faster. The test results from the combinational measurement system are compared with the results from a micrometer. It shows that this measurement system has higher precision and better repeatability, reliability and feasibility.
