Measuring system for incremental expansion and angle measurement; forms cycle of output signal of sensor that is whole number fraction of cycle duration of signal of sensor elements

摘要

Sensor elements (4) are arranged in measurement direction and generate periodic signals that contain harmonic components. The sums and the differences of the signals are related to the pattern of the sensor elements (4) and are formed in the sensor (2). A cycle of the output signal of the sensor (2) that is a whole number fraction of the cycle duration (11) makes the signal of the sensor elements (4).
