FOR noncontact online measurement, inspection and control of velocity and length in continuous process industries, Polytec has announced its LSV-300 laser surface velocimeter. It is available from Warsash Scientific Pty Ltd.

It uses heterodyne technology for high-quality speed and length measurement and can distinguish among forward, reverse and standstill motion.

With stand-off distances of 500mm or 900mm and a 60mm depth of field, it can measure speeds up to 2500m/min with 0.05% accuracy.

A signal processor provides output data quickly and communicates via an RS-232 or RS-422 interface.
