Product Description
2.1 General Description
The CHRocodile CLS is a multi-point optical sensor dedicated to non-contact surface measurement.
This sensor is based on Confocal Chromatic principle which authorizes high resolution and high speed
thickness and altitude measurement. The CHRocodile CLS can measure 192 points simultaneously
with a measuring rate of 2000 Lines/s corresponding to 384000 points/s.
This device consist in a sensor unit that contains a light source, an optical probe, a spectrometer and
all electronic and software for data processing and transmission.
In addition to be very fast and precise, the CHRocodile CLS has an original architecture with no
exposed optical cable. This unique architecture makes CHRocodile CLS sensor ideally adapted for
industrial control. CHRocodile CLS thus overcomes the device integrating constraints met in industrial
environment, e.g. on production line, induced by optical fiber cable presence.
Due to their length, their low capability to resist to torsional and elongation stress, their photometric
transmission intensity loss according to imposed radius of curvature, optical fiber cables are subject to
damage when the measuring device is exposed to high acceleration and/or rotational displacement.
PRECITEC is the first company to propose a confocal chromatic device, with all elements embedded
in one Optoelectronic unit (no apparent optical cables) in order to adapt to industrial changing
requirement.
The CHRocodile CLS can accommodate different types of optical head. These Optical Heads can be
mounted on CHRocodile CLS in a straight version or in a right angled version (see Fig. 2-1). The
Optical Head interchangeability is straight forward, as the operator just need to exchange Optical
Head and move to the right calibration table. Finally, data transmission is carried out by ETHERNET
communication. All CHRocodile CLS characterisctics are described in Section 2.7.
