Determining the working distance
The SIMATIC MV230 height profile sensor has a specific laser line length
(approx. 50 mm to approx. 75 mm) depending on the distance from the tested
object.
The distance (A) between sensor and object determines the length of the laser
line (L):
L
≈
0.24 · A
Example values
Note
The smaller the distance from the object, the better the resolution
and thus the recognition of differences on the object.

The height profile to be recorded must lie
within the sensor's working range. This
means that the distance between the tested
profile and the sensor must be a minimum
of 210 mm and a maximum of 310 mm
since parts of the object outside this range
cannot be recorded.
