The transmitters allow converting the photometric quantity “equivalent veiling luminance” – HD2021T7 – or a photometric quantity Luminance (cd/m2) – HD2021T6 – into a current (4…20 mA) or a voltage (0…10 V) signal according to the version chosen. If the acquisition station is far from the probe (>50m), it is necessary to use the current output version.The probe 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).
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
