The tunnel luminance meter is also called the brightness detector outside the tunnel and the tunnel luminance detector. The tunnel luminance meter can effectively control the lighting system of the tunnel, adjust the lighting at the entrance and exit, and ensure the safety of driving, and meet the lighting requirements. To achieve the purpose of energy-saving operation. The tunnel luminance 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 the tunnel lighting. Its design fully complies with CIE's requirements for tunnel lighting measurement, and can meet the "Highway Tunnel Ventilation and Lighting Design Specifications", and its overall design can fully meet the requirements of harsh working environments in the field.
Features of Tunnel Luminance Meter :
1. There is a good linear relationship between brightness and photocurrent.
2. The equipment has its own LCD screen, which can display the status and operation status, fault alarm and data storage function.
3. Multiple ranges are optional.
4. The photocell is calibrated at room temperature of 25°C, and the error is automatically corrected to be less than ±1% in actual operation.
5. The measurement characteristic is linear and can respond instantaneously to light changes.
6. A variety of output options, convenient data transmission.
Tunnel luminance meter installation method:
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 an appropriate position greater than 10m from the tunnel entrance. The tunnel luminance monitor is installed at an appropriate position about 4m away from the road surface outside the tunnel and 120-200m away from the tunnel entrance. With high reliability and low maintenance. The latest microprocessor technology, fully digital operation, easy installation and debugging.
Vehicles on motorways travel at a high speed, so the requirements for road conditions are relatively high. In bad weather, visibility is low and the road surface is slippery, which makes it easy for traffic accidents to occur. Therefore, it is very important to establish a road weather monitoring st...
With the popularization of transportation, vehicle safety has gradually become a focus of social concern. Low visibility is one of the main causes of road traffic accidents. In order to improve driving safety, vehicle-mounted mobile visibility meters have come into being. In this article, we will el...
