What
does it do?
Non-contact
velocity measurement of moving steel strips in rolling
mills,
plastic sheets, conveyor belts etc. It is installed in the
plane
of
the strip, about 30-100cm away from the edge. Antenna has to
be
pointed towards the edge, and at an incidence angle of 30-60 deg.
How does it work?
Emitting,
receiving and processing microwave signal at 77GHz (50mW),
How
is it interfaced?
Powered
by 24V DC, 0.5A.
Why
a steel company may need it?
To
be better able control the steel rolling process. To close the overall

History
07-July 2007 - Long distance range testing.
Photo of the working prototype.
Power spectrum graph downloaded through serial/USB link, displayed using VelTerm.exe program. Averaging accumulation length = 8 (repetitions). Estimated (extrapolated) maximal range: 120ft (with 1" horn antena). Estimated maximal range for the same target using 3" lens-horn antena: ~360ft (110m). Estimated distance measurement resolution: +/- 1cm (software dependent).
