Vaisala Present Weather Detectors and Visibility Sensors PWD Series

A MODEL FOR ALL NEEDS

Vaisala has developed the PWD series of present weather and visibility sensors to meet the unique challenges of visibility and present weather measurement in maritime, transportation, planning, and general forecasting applications. They offer a range of visibility instrumentation to ensure that you have the right combination of technology and sensors to capture the precise data that satisfies your monitoring and planning objectives without overspending on capabilities you don’t need. The sensors are easily and economically upgraded for a cost-effective and reliable solution that grows to meet your measurement needs.

EASY INSTALLATION & EXPANSION

PWD sensors are compact and lightweight, and they are factory-calibrated and plug-and-play ready. They can function as stand-alone units or as part of an Automated Weather Observing System (AWOS) with flexible mounting options on any existing mast. The measurement capabilities of all models can be easily and economically upgraded to meet your changing needs.

ACCURATE IN ALL CONDITIONS

The PWD series precisely assesses real-time visibility; and with certain units, precipitation type, intensity, and accumulation for richer data when needed. These models are built to perform under even the most demanding conditions both on land and on the sea. Vaisala’s pioneering forward scatter visibility sensor design enables the PWD series to provide unmatched, constant, reference-grade performance — even for intense precipitation and mixed precipitation.

ECONOMICAL OWNERSHIP

The weather-proof design of the PWD series increases accuracy while it reduces upkeep. The rugged, modular design has no movable or consumable parts, which limits maintenance and makes it easy to repair. The visibility sensor is well protected against contamination with the optical components pointed downwards and hoods protecting the lenses against precipitation, spray, and dust. The PWD series delivers low life-cycle costs and less burden due to very low failure rates in the field.
