Luminance detector outside tunnel

The tunnel exterior brightness detector is an on-site real-time brightness detection device developed for the special requirements of long tunnel lighting control. The tunnel exterior brightness detector quickly converts the collected optical signals into electrical signals and processes them to obtain measurement results. It provides a variety of The interface is compatible with tunnel lighting control. The tunnel brightness monitor can fully meet the requirements of the entire tunnel lighting control. The controller in the preset control mode automatically switches the lighting switch according to the preset parameters according to the measured value of the light source, providing the best value for tunnel lighting. Its design fully complies with CIE's requirements for tunnel lighting measurement and can meet the "Road Tunnel Ventilation and Lighting Design Code", and its overall design can fully meet the requirements of harsh working environments in the wild.

Product features of tunnel brightness detector :

1. There is a good linear relationship between brightness and photocurrent.

2. The equipment has its own LCD screen, which can display status operation status, fault alarm and data storage functions.

3. Multiple ranges available.

4. The photovoltaic cells are calibrated at room temperature of 25°C, and the error is automatically corrected to less than ±1% during actual operation.

5. The measurement characteristics are linear and can respond instantaneously to light changes.

6. Multiple output methods are available for convenient data transmission.

Installation method of brightness detector outside tunnel:

The tunnel light intensity monitor is installed on the wall of the designated area in the tunnel. In order to avoid damage to it due to accidents or car wrecks, it needs to be installed at a height of about 4m and at a suitable location greater than 10m from the tunnel entrance. The tunnel brightness monitor is installed at a suitable position outside the tunnel at a height of about 4m from the road surface and about 120-200m from the tunnel entrance. It has high reliability and low maintenance. The latest microprocessor technology, completely digital operation, easy installation and debugging.
