The principle of measuring the propagation time of light allows for greater ranges than with sensors using triangulation or energetic diffuse technologies
The laser heads LDS are used in heavy industrial environments where it is necessary to protect the measuring sensors and instruments against high temperature, dust, possible crashes, etc… typical of metal industry and of all production processes with heat sources.
Polytec’s compact velocimeters allows noncontact measurement of both length and the velocity of continuous material and piece goods. The measuring device quickly and reliably provides you with length and velocity values for inspection and cut-to-length applications with the precision that can only be achieved through using a laser.
