ETF Optical length measuring unit M 2622
Laser measuring for maximum accuracy
With the optical length measuring system a measuring accuracy of even better than 0.15% can be achieved. Measuring is done by a laser which can measure any material in both directions on the fly. Since the laser is not in direct contact with the material the measurement will not be influenced by e.g. a moment of inertia, a slip of the wheel or dirt on the contact surface.
