Product Description 1.Introduction to Atmospheric Visibility Sensor ProductsAtmospheric Visibility Sensor is mainly used in the field of traffic to obtain real-time visibility values by measuring the atmospheric extinction coefficient.The N2 Atmospheric Visibility Sensor uses forward scattering method to measure the total extinction coefficient of the air, and then calculates the current visibility, which is widely used in road traffic, meteorological and other industries.2.Technical features of Atmospheric Visibility Sensor1.The instrument shell is high-quality aluminum material, and is sprayed after anodization.The whole machine has excellent waterproof, dustproof and collision-proof performance;2.The instrument transmitting and receiving lenses are designed downward to greatly reduce interference from sunlight and other miscellaneous light;3.Weather phenomenon identification can be identified, such as fog, rain, snow, mixed precipitation, sunny weather, and other weather phenomena, with a high recognition rate;4.Built-in watchdog circuit to ensure reliable and stable outdoor operation for a long time;5.The instrument communication and power interfaces both contain lightning protection designs, which greatly reduce lightning strikes and static damage;6.12~24V wide voltage power supply, total power is about 1W, and the power consumption is extremely low.It can be powered by solar panels, batteries, etc.for a long time;7.The digital interface uses RS485 or RS232, the standard MODBUS protocol, and there is no need for protocol adaptation;8.The instrument can output 15s, 1min, and 10min visibility values, and can be read directly without configuration, making it more flexible to use.3.Atmospheric Visibility Sensor implementation standardsQX/T 536-2020 Forward scattering visibility meter test method4.Atmospheric Visibility Sensor Technical IndicatorsMain parametersParameter rangeResolutionerrorRange2km1m≤2km ±2%2km~10km ±5%>10km ±10%Repeatability≤4%Weather phenomenaFog, rain, snow, mixed precipitation, sunnyWeather phenomenon recognition rate≥95%Operating temperature-40~60oCWorking humidity0~100%RHWorking power supply12~24VPower consumption1Wsize610x230x360mm (Length x Width x Height)weight≤10kg5.Atmospheric Visibility Sensor installation instructions1.Installation locationThe installation location of the visibility meter needs to be selected on an open, flat, unobstructed ground, away from buildings, trees, shrubs, peaks and other objects.This ensures that the instrument's observation range is not blocked and the data is more accurate.Unnecessary optical interference should be avoided.The receiver of the visibility meter should be installed to a strong light source (such as sunlight), and the transmitter and receiver should be located in the north-south direction.2.Installation heightThe installation height of the visibility meter should be greater than 1.5m and less than 3m.The installation height exceeds 3m, the corresponding height should be calibrated.3.Installation steps3.1 Before installation, users should prepare columns and install them on the columns using the clamps provided by the instrument.3.2 Lift the instrument to a suitable position, use the bolts after the clamp to install and fix the visibility instrument.During installation, ensure that the receiver and transmitter openings are downward, otherwise they should be reinstalled.
