Lut 2.0 SPF/
Single Probe Fixed

Lut 2.0 SPF for cross rolling processes

The Lut 2.0 Single Probe Fixed configuration is ideal for rotary processes such as:

  • Assel mill
  • Reeler mill
  • Rotary sizer
  • Piercing mill

With the tube in rotation, the Lut 2.0 provides full circumferential coverage and highly accurate eccentricity measurements, even with a mandrel.

Single Probe Fixed

  • Modular online support structure is easily adapted to any production line
  • Fully motorized support structure
  • Small footprint: as little as 500 mm x 500 mm of floor space is required
  • No tube guiding required. Typically, no modifications to the line are necessary.
  • 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 can access all critical information in real time and 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

Available options

Length meter

The optional length meter is a single-axis laser velocimeter based on the interference of two beams originating from the same frequency-stabilized laser source. It is used to determine where each wall thickness and temperature measurement is made. It can be mounted directly on the support frame of the Lut 2.0 or near the Lut measurement position. Note that the length-meter is not compatible with rotating tubes.

Outer diameter profilometer

As an option, the Lut 2.0 can be equipped with an outer diameter measurement system. The information captured by the profilometer is integrated into the Lut 2.0 database. We offer a number of options from several OD gauge suppliers.
