Velocimetry  Manufacturers, Traders, Suppliers

Measuring wheels, encoders and other length and speed measuring devices are classic sensor devices for process control in the production of strip material, e.g. in steelworks or in paper production. Precise knowledge of the strip length and the current speed is essential for optimizing a production process. Polytec offers a non-contact solution consisting of length and speed measuring devices for next-level process control. Learn more about how ProSpeed® optical speed and length sensors will take your production process control to the next level.
