Converter /Tilting angle: Exchange solution for tilting angle monitoring

Home  Case Studies Converter /Tilting angle: Exchange solution for tilting angle monitoring

Compact IR thermal imaging camera was installed to provide a temperature map of the bottom shell. The cameral scans the full bottom of the shell giving options to define multiple areas /ROI to get 4-20mA output. Software automatically finds hot spots enable timely preventative maintenance.

Pilger mill in tube rolling mills - hot and cold pipe detection

  • Direct mounting / elimination distribution gear
  • Higher accuracy
  • Easy configuration of switching points
  • Fast commissioning and restart after preset

Before: Mechanical cam limit switch and absolute encoder mounted by using an additional distribution gear

Challenges

  • In steel making plants tilting angles of converters are measured by absolute encoders and monitored by mechanical cam limit switches.
  • The sensors are normally mounted by using an additional distribution gear, which causes mechanical play and inaccuracy. Furthermore, the mechanical cam limit switches are difficult to preset and not precise enough.

After: Electronic position switches and absolute encoder in one unit directly mounted without distribution gear

Solution

  • The universal encoder system U-ONE-(SAFETY-)Compact provides the same outputs as the old solution, but in just one compact and robust unit:
    • Absolute encoder
    • Electronic position switches
  • The unit can be mounted directly to the application shaft without using any distribution gear. For this Hübner Giessen provides special torsion resistant double-joint couplings. The switching points are easy to configure and the system can be restarted fastly after preset.
  • Optionally available with safety certification SIL 2/PL d.
