LaserSpeed Applications

Overview

LaserSpeed gauges measure the speed and length very accurately on any of moving surface using a non contact laser Doppler principle. They are suitable for use on any production line including the harsh environments found in steel and aluminium rolling mills.

Operating Principle

LaserSpeed Diagram

All LaserSpeed sensors use the principle of dual beam laser Doppler velocimetry to produce highly accurate measurement without contacting the product. The gauge has no moving part, uses 100% solid state digital technology and is permently calibrated.
