Luminance detector outside tunnel

Luminance detector outside tunnel measures the level of brightness or luminance created by natural light at the tunnel entrance/exit.The Luminance detector outside tunnel can fully meet the requirements of the entire tunnel lighting control. The controller in the preset control mode automatically switches the lighting switch according to the preset parameters according to the measured value of the light source, providing the best value for tunnel lighting. Its design fully complies with CIE's requirements for tunnel lighting measurement and can meet the "Highway Tunnel Ventilation Lighting Design Code", and its overall design can fully meet the requirements of harsh working environments in the wild.

Luminance detector outside tunnel installation method:

The tunnel light intensity monitor is installed on the walls of the designated area in the tunnel. In order to avoid damage to it by accidents or car wreckage, it must be installed at a height of about 4m and an appropriate position greater than 10m from the entrance of the tunnel. The Luminance detector outside tunnel is installed at an appropriate position where the height outside the tunnel is about 4m from the road surface and about 120-200m from the entrance of the tunnel. High reliability and low maintenance. Latest microprocessor technology, fully digitally run, installation

Luminance detector outside tunnel debugging is easy.
