Teknik Bilgi

HD2021T7 is used for the control of street lighting, in particular, the measurement of equivalent veiling luminance is essential to determine the threshold luminance at the entrance of the tunnels (UNI 11095:2011).  The transmitter full scale can be chosen (when ordering) between two different values:  2000 cd/m2 or 20000 cd/m2

HD2021T6 is used for road lighting control. In particular, the measurement of luminance at a 20° angle (L20) is necessary to estimate threshold luminance at tunnel entrances (CIE standard 88:2004. This standard foresees the measurement of debilitating luminance in future). Moreover, the probe can be used for calculating vertical illuminance (Ev) as prescribed in the above-mentioned standard. At the order time, it is possible to choose the transmitter sensitivity among three previously set values: 2 kcd/m², 20 kcd/m² or 200 kcd/m².  Finally, the probe can be used for any application where the measurement of luminance is required, for example projector screens, diaphanoscopes etc.
