To guarantee the directional stability of belt conveyor systems the required belt tension has to be ensured. This can be done through mechanical springs. Therefore, a possible sensor concept is shown in this paper. It describes a long-term stable measurement of the belt tension by using the electrical properties of a mechanical spring. The inductance of a spring varies inversely proportional to its length. With measuring the inductance and computing the spring extension, it can be used as a sensor. Initial experiments show that existing belt conveyor systems can be upgraded with this kind of sensor system.
