Tunnel Light Sensor Product Overview:
Tunnel Light Sensor is designed for brightness and illumination measurement in road and railway tunnels for control, monitoring and management of tunnel lighting.The Tunnel Light Sensor controller fully meets the requirements for overall tunnel lighting control. Its preset control mode allows for automatic switching of lighting switches based on light source measurements and pre-defined parameters, providing optimal tunnel lighting. Its design fully complies with CIE requirements for tunnel lighting measurements and meets the "Specifications for Ventilation and Lighting Design of Highway Tunnels." Furthermore, its overall design is fully capable of meeting the requirements of harsh outdoor working environments.
Tunnel Light Sensor Installation Method:
The Tunnel Light Sensor device is installed on the wall in a designated area within the tunnel. To avoid damage from accidents or vehicle debris, it should be installed at a height of approximately 4 meters, in a suitable location more than 10 meters from the tunnel entrance. It features high reliability and low maintenance. Utilizing the latest microprocessor technology, it operates fully digitally and is easy to install and debug.
Tunnel Light Sensor Product Features:
Corrected using a specially designed high-efficiency filter according to the CIE-specified human visual spectrum curve, conforming to visual characteristics.
Continuous linear proportional output, ensuring accurate and sensitive measurement within the corresponding equipment range.
Multiple signal output modes to adapt to different usage scenarios.
Local data storage to prevent data loss in abnormal situations.
The instrument housing has IP66 protection and a special coating for corrosion resistance.
Output signal protection function to prevent damage to user equipment in abnormal situations.
Zero-point compensation function.
