PWD22-PWD52 Describes the visibility Sensor：

PWD22 Datasheet PWD52 Datasheet

Measure main visibility and detect precipitation type

Vaisala's PWD range of existing weather detectors and visibility sensors provide you with off-the-shelf accuracy and reliability

Accurate, traceable visibility measurements

The PWD22 and PWD52 are calibrated with reference to high-precision transmissors, use proven forward scattering measurement principles to record meteorological optical ranges (MOR) and provide well-protected optics to prevent contamination.

Reliable record

The PWD series has been installed worldwide and has undergone rigorous testing procedures. In the field, Vaisala's PWD sensors have a very low failure rate and demonstrate strong robustness through high performance in harsh climates from sea to desert and from airfield to roadside deployments.

Visibility measurement for a variety of applications

Our systems provide remote visibility measurements for a variety of environments from ports and coastal areas to heliports and even wind turbines. Wherever visibility measurements are required, Vaisala provides a cost-effective and reliable solution.
