up to 5 mm profile height
up to 20 cm profile gap
Figure 5: The reach of the LTL 2000S(Q) makes it capable of measuring profiled road markings of profile height up to 5 mm, or profile gap up to 20 cm.
The advantage of the DELTA optical arrangement with a smaller illumination field in a large measurement field is illustrated in the figure 6 below compared to a system with two identical fields.
Pro profiled/textures markings, on even markings and in situations where a small debris (e.g. small stone) the instrument is lifted / tilted. The advantage of the LTL2000S(Q) optical ar- rangement is that the measurement still is correct in contrary to other systems available on the market with identical fields where the results obtained are incorrect because the illuminations field is not fully within the measurement field.
