Tunnel brightness detector

The tunnel brightness detector is a key equipment to ensure the safety of tunnel driving. Based on photoelectric conversion technology, it monitors the real-time light intensity inside and outside the tunnel through high-sensitivity photosensitive elements (such as silicon photodiodes). It has a measurement range of 0-7500 cd/m ², an accuracy of 0.1 cd/m ², a response time below milliseconds, and can quickly adapt to sudden changes in lighting. The device has an IP68 protection level and can operate stably in environments ranging from -50 ℃ to+70 ℃. It supports digital interfaces such as RS485 and can achieve remote monitoring and data storage. The lighting can be dynamically adjusted to eliminate the "black hole effect" and "white hole effect", reducing energy consumption and accident risks.

Tunnel brightness detectorThe controller with preset control mode can meet the requirements of the entire tunnel lighting control. It automatically switches the lighting switch according to the preset parameters based on the measured value of the light source, providing excellent values 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. The tunnel brightness monitoring device is installed at a suitable position outside the tunnel, about 4m from the road surface and 120-200m from the tunnel entrance. Has high reliability and low maintenance Latest microprocessor technology, digital operation, installationEasy debugging.

The tunnel luminance detector is a key device to ensure traffic safety in tunnels. Based on photoelectric conversion technology, it monitors the illumination intensity inside and the tunnel in real time through high-sensitivity photoelectric sensitive elements (such as silicon photodiodes). Its measuring range reaches 0-7500cdm², with an accuracy of 0.1cd/m² and a response time below the millisecond level, which can quickly adapt to sudden changes in illumination. The has an IP68 protection grade and can operate stably in the environment of -50℃ to 70℃. It supports digital interfaces such as RS485 which can achieve remote monitoring and data storage. It can dynamically adjust lighting to eliminate the 'black hole effect' and 'white hole effect', reduce energy consumption and accident risk
