Considering the typical measurement inaccuracy of +/- 0.05mm of the LAS40 sensors itself,
therefore a total error of +/- 0.1mm may occur.
Sheet thickness 0.3 mm: -> measuring value between 0.2 mm and 0.4 mm
Sheet thickness 0.6 mm: -> measuring value between 0.5mm and 0.7mm
For safe operation, the upper limit must be set to 0.45mm (= 150% of the nominal thickness) and
the lower limit to 0.15 mm (= 50% of the nominal thickness).
If the limits 150% respectively 50% are not sufficient, a calibration must be performed.
When dimensioning the mechanics and the sensor mounting, the Delta values Ax (permissible
deviation of the base distance due to thermal expansion, vibrations, impacts, press travel) must be
considered: According to the smallest sheet thickness, following deviations must be observed:
