Photometric Radiometric Transmitters
HD2021T6 / HD2021T7
-
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).
