Elovis µSpeed Laser Surface Velocimeter

The µSPEED Laser-Encoder from Elovis offers fast measurement of speed and length with a measurement accuracy of ± 0.05%.  With these non-contact measurement systems, users can replace tactile speedometers/rotary encoders and machine drives to achieve contact-free and maintenance-free operations.

The µSPEED laser velocimeter operates based on the doppler principle and determines the current speed and path length based on the interference pattern from the intersected two laser beams.  Therefore, it can measure almost any type of surface including light, dark, black, reflecting, matt, structured and rough surfaces without changing any parameters or settings. Users also do not need to recalibrate the equipment before any measurement tasks.

All these high-end characteristics are enclosed in a compact design to enable measurement and integration in areas where space is restricted and limited. The measurement values can be displayed as either digital quadrature output or as ASCII string through a serial interface. This speed sensor also comes with industrial BUS and Ethernet interface for easy communication with industrial interfaces. It has been used extensively in the industrial control cutting process and differential length and speed measurement.
