ELOVIS Measurement Solutions for the Metal Industry

For the metal industry ELOVIS offers measurement solutions for permanent optimization and monitoring of production machines as well as for troubleshooting. µSPEED laser encoders are used to measure speeds and differential speeds, e.g. for controlling the roll gap or for speed synchronization when several material webs are brought together. Length measurement in incoming and outgoing goods, in production machines and slitter rewinders as well as at all process stages where precise information about material lengths is required should also be mentioned. µVIS systems are used to measure the width of sheets, including single strip widths when the material is cut into numerous strips. ELOVIS SLM longitudinal light sensors are used to measure the width of finished rolls.  Some typical examples of measuring solutions in the metal industry are listed here.
