LaserSpeed Pro LS4500
LaserSpeed Pro LS4500 - non contact speed measurement
The LaserSpeed Pro LS4500 is our most cost-effective speed and length gauge (Non-Contact Length Measurement) suitable for non-metal applications. It uses advanced laser-based technology to perform length and speed measurements without contact. It will measure with a high accuracy of better than ±0.03% and repeatability of ±0.02% on any material irrespective of the surface properties. The laser Doppler principle measures surface speed and provide a very fast measuring rate exactly tracking rapidly accelerating or de-accelerating processes. Unlike contact encoder wheels 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 LS4500 is suitable for use on any production line including materials as diverse a non-wovens, mineral wool, paper and plastic films. Regardless of your production line speeds or product type LaserSpeed delivers precise, reliable measurements day in, day out.Click here for the LaserSpeed – Metals – LS8500, LS9500 non-contact speed & length measurement

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.
