PWD10, PWD20, and PWD20W Visibility sensor Description：

PWD10、PWD12、PWD20 Datasheet PWD20W Datasheet

For accurate visibility measurement

Sensors designed for a variety of visibility measurement applications including: road weather, waterway visibility measurement, and wind turbine applications such as obstacle light control.

Accurate and traceable

The PWD sensor uses a proven forward scattering measurement principle to measure the meteorological optical range (MOR).

Easy installation

All of Vysala's PWD sensors are compact (less than a metre long), lightweight, and come with cables and connectors for easy installation, which can be fitted to any existing mast in a variety of ways.

PWD20W- Ideal for wind turbine applications

The challenging conditions of wind turbines require robust and reliable equipment, such as the visibility sensor PWD20W, which cost-effectively supports obstacle lamp control and a range of other wind applications.
