The ES-S220 Tunnel Luminance Monitor fully meet the requirements for comprehensive tunnel lighting control. Controllers with preset modes automatically switch lighting based on measured light values \u200b\u200band predefined parameters, ensuring optimal brightness levels for the tunnel. The design of the ES-S220 series detectors fully complies with CIE standards for tunnel lighting measurement and the *Code for Design of Ventilation and Lighting of Highway Tunnels*; furthermore, the overall design is robust enough to withstand harsh outdoor operating environments.<\/p>\n
Installation:<\/p>\n
The ES-S221 tunnel light intensity\/color temperature detector is mounted on the sidewall inside the tunnel, at a distance from the entrance equal to the tunnel’s clear height. To prevent damage from accidents or vehicle wreckage, the ES-S221 tunnel luminance detector should be installed at a height of approximately 4 meters.<\/p>\n
The ES-S222 tunnel illuminance detector is best installed at a location corresponding to the tunnel portal, at a distance from the entrance equal to the stopping sight distance. It features high reliability, low maintenance requirements, advanced microprocessor technology, fully digital operation, and ease of installation and commissioning.<\/p>","protected":false},"excerpt":{"rendered":"
