Tunnel Illumination Detector—a tunnel light intensity monitor@2022 has been updated Beleuchtungsdetektor im TunnelFT-DN1 is installed on the wall of the tunnel area.
In order to avoid damage to it due to accidents or car wreckage, it needs to be installed at a distance of about 4m.
Height, the appropriate position is greater than 10m from the tunnel entrance
.
The tunnel brightness monitor is installed at an appropriate position at a height of about 4m from the road outside the tunnel and about 120-200m from the tunnel entrance
.
The tunnel brightness monitor can meet the requirements of the entire tunnel lighting control.
The controller in the preset control mode automatically switches the lighting switch according to the measured value of the light source according to the preset parameters, which provides the best value for the tunnel lighting
.
Its design fully complies with CIE's requirements on tunnel lighting measurement, and can meet the "Design Specification for Highway Tunnel Ventilation and Lighting", and its overall design can fully meet the requirements of the harsh working environment in the field
.
Product features: 1.
There is a good linear relationship between brightness and photocurrent
.
2.
The device has its own LCD screen, which can display the status operation, fault alarm and data storage function
.
3.
Multi-range optional
.
4.
The photocell is calibrated at room temperature of 25°C, and the error is automatically corrected to less than ±1% in actual operation
.
5.
The measurement characteristics are linear and can respond instantaneously to changes in light
.
6.
A variety of output methods are available, and data transmission is convenient
.
Installation method: The tunnel light intensity monitor is installed on the wall of the tunnel area.
In order to avoid damage to it due to accidents or car wreckage, it needs to be installed at a height of about 4m and a suitable position greater than 10m from the tunnel entrance
.
The tunnel brightness monitor is installed at an appropriate position at a height of about 4m from the road outside the tunnel and about 120-200m from the tunnel entrance
.
With high reliability and low maintenance.
The latest microprocessor technology, fully digital operation, easy installation and debugging
.
