Shanghai Xunji Electric Equipment Co., Ltd.

Brightness Detector RR Series Light Intensity Detector is an on-site real-time brightness detection equipment developed by American R Company for the special requirements of long tunnel lighting control.

The housing of the R series light intensity detector is made of high-grade aluminum alloy material, and the protection level reaches 100%, which fully ensures the stability of the equipment in harsh environments such as the open air. The front window is sealed with a high-strength transparent polycarbonate gasket, and there is a removable gasket at the rear to facilitate the connection of the main power supply and controller cables. The use of internal heaters can minimize the impact of temperature factors on photovoltaic cells composed of silicon photodiodes, further ensuring the measurement accuracy of the instrument.
The new light intensity detector makes the entire lighting system more efficient. The system can adjust between natural light and artificial lighting in a timely manner according to the user's needs to ensure driving safety and save energy.
