Strip edge position sensing VKI3

Inductive strip edge position measurement in the rolling mill

[Translate to English:] Einbausituation VKI3

In the harsh environment of a rolling mill where there is a high presence of rolling oil, atmospheric pollution and dirt, optical sensors that are used for monitoring the edge position of the strip require intensive maintenance and even then do not fulfil today's requirements in terms of operational reliability and availability. EMG's VKI3 sensor uses an inductive measuring principle with a coil system, which is designed to reliably detect the precise position of the edge of metal strip and foil material in this environment in a contact-free manner.

The single-sided VKI3 system is installed flush into the transfer tables underneath the strip to be measured, where it is mechanically protected by a plastic wear plate. The current strip edge positions, the strip centre position and the strip width (optional) are continuously output via the signal interface. The VKI3 sensor contains the evaluation electronics and does not require a higher-level control cabinet. Conventional bus systems, namely Profibus and Ethernet, are available as the system interface.

Customer benefits:

  • Maintenance-free

  • Single-sided inductive measuring system

  • High-precision strip edge, strip centre and strip width measurement

  • Compact design for confined installation conditions

  • Electronics integrated into the measuring beam without any other external components

  • Integrated, factory-calibrated sensor system (measuring and reference coils)
