LaserSpeed® Pro X Series

LaserSpeed Pro X Series

Designed for the Extreme Environments Found in Steel Mills and Casters

LaserSpeed®Pro gauges have set the standard of innovation for accuracy and reliability for non-contact length and speed measurement. Utilising the principle of Laser Doppler Velocimetry (LDV) LaserSpeed Pro can measure the velocity and length of a moving surface or object extremely accurately using a non-contact method. The LaserSpeed® Pro 8500X and 9500X Series gauges are designed for the toughest extreme conditions in steel mills and steel casters where heavy steam, mist and sprays occur along with extreme temperatures. The stainless steel housing protects the gauge, whilst a built-in air purge helps keep the quick-change window clean.

The LaserSpeed® Pro is the most accurate gauge available on the market today delivering an accuracy of better than ±0.03% and repeatability of ±0.02% on any material irrespective of the surface properties. The LaserSpeed® Pro embraces Industry 4.0 connectivity, which means integrating more easily than ever into production networks to provide real-time data exchange and improve process control and efficiency.

LaserSpeed® pedigree

LaserSpeed® gauges can measure the speed and length of any product 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 thousands of LaserSpeed gauges installed in all types of industrial applications worldwide.

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.

Suitable for harsh environments

All LaserSpeed gauges are extremely rugged with a sealed IP67 housing with built-in air/water cooling facility. Suitable for installation in tough industrial applications.
