Verfahren zur Erfassung der Position und/oder Bewegungsgeschwindigkeit eines zwischen zwei Schaltstellungen hin und her bewegbaren Stellelements

摘要

The invention relates to a method for determining the position and/or the speed of motion of a control element which can be moved back and forth between a first and second switching position. According to said method, an immersion body which is connected to the control element is guided through at least one stationary plunger coil, synchronously with the motion of said control element. The voltage that is generated as a result of the immersion body moving in relation to a permanent magnet and/or a permanent magnet moving in relation to the plunger coil is detected as a signal for the speed of motion of the control element. The changes in impedance and or a current that are caused as a result of the movement of the immersion body in the plunger coil are detected as a signal for the position of the control element.
