Functional Description of the Precision Glass Scale Linear Encoders

The TR linear measurement systems of the LT series work according to the principle of photoelectric scanning of an absolute coded glass scale. A sensor array scans several tracks that contain high resolution measurement information on the 3D coordinates and angular position between the glass scale and the scanning unit. While evaluating the measurement signals, the coded measurement position is determined by the sensor signal, and due to the additional measurement information, guidance and adjustment errors are completely corrected.
