LaserSpeed® pedigree

LaserSpeed gauges measure the speed and length of any products using an optical, non-contact technology called Dual Beam Laser Doppler Velocimetry. LaserSpeed gauges were first introduced to the metals industry in 1984 and have been growing in usage ever since. There are now over 8,000 of LaserSpeed gauges installed worldwide There is a wide range of models to suit every application whether measuring hot or cold materials.

High performance

A breakthrough in electro-optics design enables LaserSpeed gauges to produce highly accurate, non-contact speed and length measurements at a reasonable cost. To accomplish this the LaserSpeed gauge uses Laser Doppler Velocimeter technology coupled with autocorrelation, the most advanced, digital signal processing algorithm and a new single-chip integrated circuit technology. LaserSpeed gauges have no moving parts, use 100% solid-state digital technology, and are permanently calibrated – resulting in significant time and money savings.

Replace contact tachometers

With an accuracy better than ±0.03%, irrespective of the material, temperature, surface or speed the LaserSpeed is ideal for replacing traditional contact tachometers that are prone to measurement errors caused by slippage, dirt build-up, and day-to-day wear problems.

Measure zero speed and direction

The LaserSpeed LS9500 models use an enhanced version of autocorrelation, coupled with an Acusto-Optical modulator that enables the gauges to measure down to zero speed and automatic direction detection. These gauges are ideal for measuring the length of material on start/stop processes such as sawing lines. The gauge can even track forward or reverse movement without affecting the length accuracy.

Suitable for harsh environments

All LaserSpeed gauges are extremely rugged with a sealed IP67 housing with a built-in air/water cooling facility. For use within a mill environment with extremes of heat, steam and spray additional levels of protection are provided by the E or X versions of the gauge.
