SPEED-
SMARTSENSOR
General description
The measuring devices type
µSPEED-smartsensor
are laser sensors based on the
Doppler effect and are used for non-contact measurement of length and velocity of
surfaces with diffuse reflection. They provide extremely accurate measurement without
markings or rods. This measuring equipment is thus particularly suitable for its use in
process control and quality assurance. It allows the optimization of cutting operations,
positioning and dosing in the case of flat or rope-like material such as paper, metal, wood,
textile, plates, sheets, wires and cables.
Function
The measurement is non-contact and therefore completely free of wear and tear. It is
performed by scanning the product from a laser-based measuring unit that projects a
striated pattern on the object. The measured object backscatters the laser beam into the
measuring unit. The frequency of the backscattered light is directly proportional to the
measured object's velocity.
