4.3.4 Position and location of the sheet between the sensors
Ideally the sheet should be transferred through the middle of the sensor gap. This guarantees
reliable and accurate results of the measurement.
The sheet must be guided perpendicular to the laser axis; otherwise it comes due to geometry to
measurement errors.
Avoid mechanical damage due to incoming material and take appropriate measures such as
baffles.

4.3.5 Sensor gaps
The gap between the sensors is derived from the sensor name in mm. The sensor LAAS40 has a
gap of the sensors of 40 mm with a tolerance of ± 2.5 mm.
In the final mounted and aligned state the start-up at the L20 must be done by performing the
"Measuring channel calibration".
This is done with a calibration sheet having a defined thickness in order to define the total distance
between the sensors.
This total distance serves as a reference for the thickness measurement and must remain constant
during operation.
This requires a correspondingly stable and rigid mechanism, see chapter 3.1.1 "Planning
Information for Mechanics".
