Building 1, Weifang High tech Zone Optoelectronic Industry Accelerator (Phase I), No. 155 Guangdian Circuit, Weifang High tech Zone, Shandong Province
Product Overview:
The tunnel light intensity monitoring device can meet the requirements of the entire tunnel lighting control. The controller with preset control mode automatically switches the lighting switch according to the preset parameters based on the measured value of the light source, providing value for tunnel lighting. Its design complies with CIE's requirements for tunnel lighting measurement and can meet the "Design Specification for Ventilation and Lighting of Highway Tunnels". Moreover, its overall design can meet the requirements of harsh outdoor working environments.
Installation method:
The tunnel light intensity monitor is installed on the walls of the designated area inside the tunnel. In order to avoid damage caused by accidents or car debris, it needs to be installed at a height of about 4 meters and at an appropriate position greater than 10 meters from the tunnel entrance. Has high reliability and low maintenance Microprocessor technology, digital operation, easy installation and debugging.
