What can you do if you have transparent, semi-transparent and highly reflective objects?
The measuring principle desires an object that reflects the light diffusely. Semi-transparent, transparent and
highly reflective objects do not have this feature.
•
When measuring on semi-transparent objects, the light enters the object and so the measured distance is
larger than the actual distance is.
•
Light will pass through a transparent object so a measuring signal is not available.
•
A highly reflective object only has a direct reflection and it is not possible to work with it. For such an
application, ask the Baumer electric sales staff.
to measure these objects, it is only possible if you place a diffuse reflecting surface on the object (sticker,
etc.)
!
Semi transparent objects:
the light enters the object.
the measured distance is larger than the
real distance
Transparent objects:
The light passes the object without a
diffuse reflection.
No measurement is possible
Highly reflective objects:
Only direct reflection
No measurements possible
