Apparatus and method for detecting the position and the speed of a measurement object

2005 
An apparatus and method for detecting position and speed of a measurement object (5) relative to a sensor (1), wherein the sensor (1) and the measurement object (5) are arranged relative to one another, wherein the sensor (1) has a measuring coil having and (2) with at least one, preferably a plurality of voltage tap (s) attached (4) and to the measurement object (5) and with the measuring coil (2) electromagnetically coupled to the target (7) where the sensor is an electronic component (6) for adding to the sensor (1) is associated tapped voltages, are characterized in that identifies for the simultaneous measurement of position and velocity of the target (7) comprises two parts (8, 10) with respect to the simplest possible construction of the sensor, wherein a part (8) is constructed from an electrically conductive material and the other part as a magnet (10) is running and that by an evaluation circuit (11) from the output signal of the electronic B auteils (6) for adding the voltages tapped one of the position of the target component proportional voltage Up and the velocity of the target component proportional voltage Uv is determined.
