Product description
Caption:
Y_G1
distance between measured points in one measurement plane (here: Y_G1 = 0.1833 m)
Y_G2
distance between measured points between two laser pulses (here: Y_G2 = 0.0742 m)
Y_S
width of measured point (here: Y_S = 0.0349 m)
X_Layer height of individual measured point (here: X_Layer = 0.3491 m)
The following tables illustrate some values as examples:
In measuring mode for a scanning frequency of 12.5 Hz, you can choose between an angle
resolution that is constant or changes according to sector (settable with the SICK LaserView
Customer Edition). This function is not possible for field monitoring.
The scanning frequencies of 25 Hz and 50 Hz only allow for constant angular resolution.
