Diameter measurement of coils

optoNCDT ILR2250-100 laser distance sensors from Micro-Epsilon measure the coils based on the phase comparison method. For this measurement task, a sensor is mounted at a distance of 0.2 to 10 m facing the radius of the coil. It continuously measures the distance to the coil. As the diameter of the steel strip coil is constantly reduced by the unwinding process, the distance between the coil and the sensor consequently increases. The sensor reliably detects this change in distance and transmits it as a measurement value via the RS422 serial interface to the production process control system. An early warning message can now be issued via the control system, even before the material has been completely unwound.
