Online sensor for production line control of the retroreflection properties of traffic sign sheeting materials.

GRX Online is an industrial sensor for continuously monitoring of retroreflective properties of sheeting materials at the production line. Retroreflective sheeting materials are used for traffic signs, high visibility safety clothing, license plates and, conspicuity materials.

GRX Online measures the value RA (coefficient of retroreflected luminance at night)

RA is an important factor in the on-site quality control of road traffic signs.

Overview of GRX Online:

The GRX online sensor measures Ra values for a given entrance angle for seven observation angles. The GRX online sensor has a build in entrance angle of either -4 degrees (ASTM type) or 5 degrees (CEN type). The observations angles are 0.2, 0.33, 0.5, 0.7, 1.0, 1.5 and 2.0 degrees. All observations angels are measured simultaneously. The sensor measures all types and colors of retroreflective materials, when calibrated with one single white retroreflective standard with known RA. A calibrations standard can be supplied as an option by DELTA.
