Measuring wheel encoders
Measuring wheel systems use a wheel to record linear movements, which they then convert to speed or position values. These systems do not require a reference point on the surface to be measured, making them well-suited to measuring a wide range of surfaces. The integrated spring ensures that the wheel exerts a consistent pressure on the surface, thereby guaranteeing slip-free measurement.
