Features

• Designed and tested for aviationapplications with Vaisala AviMetâ

systems

• Complete solution for weatherdata collection

• Wide range of installation, powersupply, and communicationoptions

• ICAO- and WMO-compliantsensors with long calibrationintervals

• Surge protection for power input,sensor connections, and outputdata connections

Optimized for Airport WeatherObservation NeedsAWS310‑SITE is specially designed andtested for Vaisala AviMet AutomatedWeather Observing System (AWOS) andLow‑level Windshear Alert System(LLWAS), ensuring complete end‑to‑endsystem integration. With Vaisala AviMet,users are able to collect and viewweather data remotely, as well asmonitor and control the AWS310‑SITEobservation stations.

A Complete SolutionThe AWS310‑SITE solution includeseverything required for accurate andreliable weather measurements: theenclosure, a wide variety of sensoroptions, installation kits, power supply,and communication devices.

The solution has a robust, tightly sealedIP66 stainless steel (AISI 316) enclosureto protect the electronics. AWS310‑SITEis available with different installation andpowering options according to customerneeds and site requirements, including asolar-powered option for remotelocations.

The AWS Client software is included formaintenance purposes to support setup,diagnostics, and data retrieval.

Data CollectionMeteorological data is sent to the airportweather observation system in real time.There are several standardcommunication options available,including landline communicationthrough RS‑232, RS‑485, or leased-linemodem, or wireless communicationthrough a UHF/VHF radio interface.

To provide redundancy in safety-criticalairport applications, data can be sentsimultaneously via 2 parallelcommunication ports. The data is alsosaved on the weather station’s externalmemory card. The stored log files can beexported to external applications.

Excellent Long-term StabilitySensor calibration is vital to accurate andreliable observations. The sensors ofAWS310‑SITE ensure excellent long-termstability with a low risk of drift or suddenchanges in calibration. This results inlonger calibration intervals, lowermaintenance costs, and reduceddowntime.

Installation OptionsThere are several standard masts andmast installation kits available forAWS310‑SITE. Frangible options includepole masts DKE110F, DKP721, and DKP711and lattice mast DKE200. Vaisalafrangible masts are impact-tested, andthey comply with the frangibilityrequirements set in the followingspecifications:

• ICAO Doc 9157 Aerodrome DesignManual, Part 6 Frangibility, FirstEdition, 2006

• FAA AC 150/5345‑45C – Low ImpactResistant Structures, 2007

Standard Safety FeaturesAWS310‑SITE includes surge protectionfor the power input, sensor connections,and output data connections. Surgearrestors protect the AWS310‑SITE unitfrom potential damage caused by pooror variable power quality, or otherpossible surges.

Vaisala Automatic Weather Station AWS310‑SITE is anautomatic weather station that is optimized for airportweather observations. Based on the proven VaisalaAWS310 weather station, AWS310‑SITE provides reliableand accurate weather measurements for aviationapplications using ICAO- and WMO-compliant sensors.
