Overview

The tunnel light intensity detector can meet the requirements of controlling the entire tunnel lighting. 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 the best 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.

Product Details

Product Overview:

　　Tunnel light intensity detectorThe requirement of being able to control the entire tunnel lighting is met. The controller with preset control mode automatically switches the lighting switch based on the measured value of the light source and preset parameters, providing the optimal 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:

　　Tunnel light intensity detectorInstalled on the walls of designated areas within 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 The latest microprocessor technology, digital operation, easy installation and debugging.
