Linear or angular displacement sensor using an optical incremental coder

摘要

The sensor (6) uses an optical incremental coder (3). The incremental coder (30 is a standard component of a computer mouse. The monitored moving part is the spindle (1) of a screw device, the spindle (1) rotates the roller (2). Alternatively the sensor is placed directly on the end of the spindle (1) or the spindle (1) indirectly drives the roller (2), in the latter case the axis (8) of the sensor is placed parallel to the spindle (1)
