LaserSpeed Pro LS4500
Non-Contact Speed Measurement
Over the last 30 years, LaserSpeed® gauges have set the standard of innovation for accuracy and reliability for non-contact length and speed measurement. With over 8,000 installations worldwide in all types of in-process applications. The LS4500 is suitable for use on any production line including materials as diverse as non-wovens, mineral wool, paper and plastic films wood panels or insulation materials. Regardless of your production line speeds or product type LaserSpeed delivers precise, reliable measurements day in, day out.
LaserSpeed Pro 4500 measures process speed and length using a non-contact method and is a direct replacement of existing contact rotary encoders to improve accuracy and reliability of in-process measurement. Unlike contact encoders the LaserSpeed is not susceptible to errors due to slipping, wheel pick up or wear and will provide a more dependable measurement over the long term. 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 productions networks for providing real-time data exchange and for improving process control and efficiency.For use in the metals industry please view our LaserSpeed – Metals LS8500 and LS9500 models.

LaserSpeed gauges can 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 thousands of LaserSpeed gauges installed in all types of industrial applications worldwide.
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.
