LaserSpeed Pro 4500

Measurement speeds up to 12,000 m/min with unprecedented precision. LaserSpeed Pro 4000 is used for all continuous or discontinuous length measurements. This encoder is based on the proven Laser Doppler Velocimetry principle. Measures in one direction. For bidirectional measurements see the LaserSpeed Pro 9500.


With more than 25 years of proven technological performance, Laserspeed is the benchmark in the field of continuous length and speed measurement.

The Beta LaserMike LaserSpeed® sensor was one of the first non-contact length and speed gauges on the market. Since then it has set the standard for innovation, accuracy, reproducibility, versatility and reliability. The LaserSpeeds are successful in the accurate and precise measurement of length and speed and now more than 8,000 sensors in various production environments worldwide. LaserSpeed has proven itself in numerous metal applications, including continuous casting, hot and cold strip, temper and skin pass, pipe and tube, bar and rod, coil and strip, extrusion and other processes. With the new innovations, we have taken the system to the next level! Thanks to new features in the field of connectivity, communication and control consistent with Industry 4.0, the LaserSpeed Pro is easy to integrate into production networks, generating real-time data that ensures a constant quality of your product.

The LaserSpeed has no slip and measures faster than a traditional encoder. Measuring errors by dirt intake, wear of the measuring wheel, material compression, vibrations etc. can be prevented by using the non-contact BetaLasermike LaserSpeed.

The LaserSpeed is permanently calibrated and has no moving parts. With a repeatability of 99.98% the LaserSpeed is the best replacement for standard (measuring wheel) encoders.

The LaserSpeed can not leave unwanted traces on your product!
