Windows
The R-GAGE sensor can be placed behind a glass or a plastic window, but the configuration must be tested and the distance from the sensor to the window must be
determined and controlled prior to installation. There is typically a 20% signal reduction when the sensor is placed behind a window.
Polycarbonate at 4mm thickness performs well in most situations, but the performance depends on filler materials. Thinner (1 to 3 mm) windows have high reflection. The
amount of reflection depends on the material, thickness, and distance from the sensor to the window.
Locate the sensor in a position of minimum reflection from the window, which will repeat every 6.1 mm of distance between the sensor and the window. The positions of
maximum reflection from the window repeat between the minimums, and decrease in effect until the window is approximately 150 mm (5.9 in) away. Consult the factory for
pre-tested window materials which can be used at any distance without issue.
Additionally, the face of the window should be protected from flowing water and ice by use of a flow diverter or hood directly above the window. Falling rain or snow in the
air in front of the window, light water mist, or small beads on the face of the window are typically not an issue. However, a thick, continuous surface of water or ice directly
on the face of the window can be detected as a dielectric boundary.
