A7.2 - Contactless Measurement of Metallic Targets by a Specially Designed Position Sensor

It is a well known technical problem to fix a separate magnet as target for measurement. The innovation of the position sensor presented here is a special geometric form of flat coils which are arranged as a couple. These coils are electrically interconnected to an alternating current half bridge. The metallic target moves over the coils in a non contacting manner and in a defined working distance. The only condition for the target is to...
