Lut 2.0 SPS/
Single Probe Scanner

The Lut 2.0 SPS for longitudinal mill

The Lut 2.0 Single Probe Scanner is best suited for longitudinal milling processes such as:

  • Sizing mills
  • Stretch reducers
  • Retained mandel mills

The Lut 2.0 SPS unit can scan over 360˚ or be set at any fixed angular position around the tube. The resulting wall thickness profiles help operators adjust rolling mill operating parameters.

Single probe scanning and positioning device

  • Scanning unit completes an entire cross-sectional profile in under six seconds
  • Position probe at any fix angle
  • Not affected by a mandrel. Can be installed directly at the exit of the mill.
  • Small footprint with as little as 1200 mm x 3000 mm of floor space is required
  • No tube guiding required
  • Built to sustain direct tube impact 
  • Integrated turnkey equipment with all support systems included.

Key hardware advantages

  • Marathon™ laser, with a diode lifetime of 6 billion shots, does not require any regular maintenance
  • Durabeam™ fully sealed optical assembly for years of maintenance-free operations
  • PDL™ provides a wide working margin (>350mm) so the Lut 2.0 can operate at a safe distance from the tube
  • TWM™ high-sensitivity detector is naturally immune to ambient vibrations.

Intuitive user interfaces

The Lut 2.0 thickness gauge continuously monitors tube production to attain better mill yield. Through the user interface, operators have access to all critical information in real time. Any archived data can be recalled and visualized at any time. The customizable user interface allows the user to visualize:

  • Tube profiles
  • Average values 
  • Production trends

The Lut 2.0 advanced analytics module:

  • Detects and quantifies eccentricity orders individually
  • Measures the position of heavy/light ends
