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 cali-
brated with one single white retroreflective standard with known R
A
. A calibrations standard can be sup-
plied as an option by DELTA.

When the sensor is powered correct the green LED on the rear cover plate will be flashing slowly (1 Hz).
Mounting the sensor in the production line
Mount the sensor so the black end cover (with the measurement window) is parallel to the sheeting and
with approximately 100 mm. The illumination angle (-4° or +5 degrees) is determined by the internal optics.
