Linear incremental measuring system for measuring speed and displacement |
摘要 |
The linear incremental measuring system comprises an incremental scale, a scanning unit for generating two analog signals, which are displaced in phase in a direction depending on the direction of the scanning movement, and a processor for generating digital signals from the analog signals and for delivering said digital signals to a bidirectional counter, which is used to control a display device and/or a control device. In order to detect in a simple manner the velocity of the scanning movement relative to the scale and to generate a voltage that is proportional to that velocity and can be used to control a machine, digital signals derived from the analog signals are delivered to a digital-to-analog conversion circuit, which delivers an analog voltage that is proportional to the velocity of the scanning movement and has a polarity that is dependent on the direction of that movement.
