Conventional length measuring devices
using the principle of frequency shift, the
so-called “Doppler-effect”, are suitable for the
measurement of flat materials such as paper,
steel sheet or textile. However, this technology
encounters difficulties for length measurement
of profiles with round or blank surfaces.
The technology of the PRECILENGTH
6000, which defines the length through
comparison of image patterns, is also
reliable for round products and for products
with blank surfaces.

www.sikora.netSIKORA has developed a system called
PRECILENGTH 6000 for non-contact online
measurement of lengths of hoses and tubes
and length measurement of extruded round
products. It assists by defining the product
profile and its movements and calculating the
speed and the produced length calculated.
In combination with two laser diodes, two
image sensors are positioned next to each
other. The product passes the first image
sensor, which defines the shadow of the
product shape. The exposure of the second
image sensor occurs when the product
shape, which has been recorded by the first
image sensor, passes the second sensor.
Hence, the characteristics of the shapes of
both sensors are identical.
The delay time for the exposure of the second
image sensor is calculated and controlled
adequately by the result of the correlation of
both characteristics of the contours. Thus,
PRECILENGTH 6000 exactly determines the
produced length of the hose or tube.
