An industrial laser surface velocimeter (LSV) must be able to withstand the harsh conditions typical in a mill environment, high temperatures, steam, dirt and moving machinery.

Polytec’s Industrial Laser Surface Velocimeter available from Warsash Scientific is specifically designed to measure the velocity and length of billets, slabs, plates, tubes and profiles for online control and inspection of hot and cold mill processes.

By incorporating advanced non contact laser measurement technology, the LSV eliminates common problems that plague traditional contact-wheel measurement methods such as slippage, chatter, changing wheel diameter and frequent maintenance.

An air wipe is used to protect the optics and a liquid cooled housing shields the unit from the intense heat.

Polytec designs LSVs that are reliable. Nucor Steel in Darlington, South Carolina have realised improved measurement performance since upgrading to laser surface velocimeters in their steel mill to control billet cut-length to better than ±0.5 inch on all 4 strands.
