Abstract
This study presents an analysis of the parameters to generate the electromagnetic fields of the induction coils for the application of Hall Effect sensor to classify the aluminum thickness and the classification of the metal materials. In this research three types of induction coil are considered: Type A with one layer, Type B with two layers, and Type C with three layers. Four experiments were conducted. The electromagnetic field of Type C is found to be 11.90% greater than Type B, and 29.26% greater than Type A. The core temperature of Type C with 1 A current applied was found to be 3.50% hotter than Type B and 5.14% hotter than Type A. The classification of the aluminum thickness with the frequency range of 100 Hz to 1.4 kHz are suitable for identifying the thickness of 1, 2 and 3 mm. In terms of the classification of metal materials with all the three types of the induction coil, it can be separated clearly from the samples which consist of steel, stainless steel and aluminum. The total error by using Hall Effect sensor is ±0.5702%.
