Tunnel brightness monitor

Tunnel brightness monitor is an on-site real-time brightness detection device developed for the special requirements of long tunnel lighting control.Tunnel brightness monitor can fully meet the requirements of the entire tunnel lighting control. The controller with preset control mode automatically switches the lighting switch according to the preset parameters based on the light source measurement value, providing the best value for tunnel lighting. Its design fully meets the CIE requirements for tunnel lighting measurement and can meet the "Highway Tunnel Ventilation Lighting Design Specifications", and its overall design can fully meet the requirements of harsh outdoor working environments.

Tunnel brightness monitor product features:

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

2. The device is equipped with an LCD screen that can display operating status, fault alarms and data storage functions.

3. Multiple ranges are available.

4. The photocell is calibrated at room temperature of 25℃. In actual operation, the error is automatically corrected to less than ±1%.

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

6. Multiple output modes to choose from, convenient data transmission.

Tunnel brightness monitor installation method:

Tunnel brightness monitor is installed on the wall of the designated area in the tunnel. In order to avoid damage due to accidents or car wreckage, it should be installed at a height of about 4m and at an appropriate position greater than 10m from the tunnel entrance. Tunnel brightness monitor is installed outside the tunnel at a height of about 4m from the road surface and at an appropriate position about 120-200m from the tunnel entrance. It has high reliability and low maintenance. The latest microprocessor technology, fully digital operation, installation

Easy debugging.
