Measuring device with dual channel scanning

摘要

The device has a magnetic sensor (3) detecting magnetic field of a magnetic field generating device stationary with respect to a rotating shaft (2). An optical sensor (4) detects light emitted from a light source (6) i.e. LED, where the light is reflected or transmitted by an encoder disk (5) that is stationary with respect to the shaft. A signal processing unit receives data from the magnetic sensor unit and another data from the optical sensor, and determines an angle of rotation of the shaft from the received data, and/or determines the angle of rotation of the shaft from the latter data. An independent claim is also included for a measuring device for determining a position and/or an angle of rotation of a body that carries out a translatory and/or a rotary motion, comprising detection unit.
