Roll Change Detection: High temperature proximity for wet areas with heat radiation
Best solution for roll change proximity under most aggressive environment
- Reduction in roll change time to maximize production/ equipment availability
- High ambient temperature electronics (1000C and 1200C)
- Cable protection system to protect from flying scales, sparks
- PBT housing material prevent corrosion of the housing easy to replace during shutdown
Integrated Cable Conduit System
Challenges
- Delays/interruptions in roll change as the feedback from proximity was not reliable
- Detection in harsh operating environment continuous water from spray headers; high ambient heat from the strips.
- Cable damage due to flying chips / scale
- PVC cable crackling from temp. cycling
Withstanding Continuous Water Spray/ Steam. IP67/68/69 K Protection
Solution
The high accuracy distance sensor with radar system-
- Contactless, inline measurement of slabs, strips, and plates (up to 1600 °C).
- Accuracy up to ±300 µm even in harsh environments
- Independent of alloy or metal type.
- Eliminates radiation hazards and reduces cost.
