80KM visibility sensor

1、80KM visibility sensor Product Introduction

The N80 model 80KM visibility sensor uses the forward scattering method to measure the total extinction coefficient of air, and then calculates the current visibility.It is widely used in road traffic, meteorology and other industries.

2、80KM visibility sensor Technical Features

1.The instrument casing is made of high-quality aluminum, anodized and then painted, providing excellent waterproof, dustproof, and impact-resistant performance.

2.The transmitting and receiving lenses are designed to face downwards, greatly reducing interference from sunlight and other stray light.

3.Weather phenomenon recognition: It can identify fog, rain, snow, mixed precipitation, clear skies, and other weather phenomena with a high recognition rate.

4.Built-in watchdog circuit ensures reliable and stable operation during long-term outdoor use.

5.Both the instrument's communication and power interfaces are equipped with surge protection, minimizing damage from lightning strikes and electrostatic discharge.

6.Wide voltage power supply (12~24V), total power consumption is approximately 1W, with extremely low power consumption, allowing for long-term power supply using solar panels or batteries.

7.Digital interfaces use RS485 or RS232, standard MODBUS protocol, requiring no protocol adaptation.

8.The instrument can output visibility values for 15 seconds, 1 minute, and 10 minutes, which can be read directly without configuration, making it more flexible to use.

5、80KM visibility sensor Installation Instructions

1.Installation Location

The visibility meter should be installed on an open, flat, unobstructed surface, away from buildings, trees, shrubs, peaks, and other obstructions.This ensures unobstructed observation range and more accurate data.

Avoid unnecessary optical interference.The receiver of the visibility meter should be installed with its back to a strong light source (such as sunlight), and the transmitter and receiver should be oriented north-south.

2.Installation Height

The installation height of the visibility meter should be greater than 1.5m and less than 3m.If the installation height exceeds 3m, calibration should be performed accordingly.

3.Installation Steps

3.1 Before installation, the user should prepare a support column and use the clamps provided with the instrument to install it onto the column.

3.2 Lift the instrument to a suitable position and use the bolts behind the clamps to secure the visibility meter.During installation, ensure that the receiver and transmitter openings face downwards; otherwise, reinstallation is required.
