WindObserver IS Ultrasonic Anemometer for use in Hazardous Areas
The WindObserver IS system is particularly suited to offshore oil production platforms, support tankers, drilling platforms, onshore petrochemical plants and other hazardous petrochemical environments
The WindObserver IS system is particularly suited to offshore oil production platforms, support tankers, drilling platforms, onshore petrochemical plants and other hazardous petrochemical environments. The system provides wind speed and direction data for use in producing offshore meteorological observations in accordance with UK CAA CAP 437.
The WindObserver IS is certified as ‘Intrinsically Safe’ for use in the ‘Hazardous Area’, whilst the associated power and communications interface is located in the ‘Non Hazardous Area’.
The ATEX, IECEx & UKEX certification ensures that the wind system may be deployed on a worldwide basis without the need for expensive local recertification.
The system requires no regular maintenance, beyond a visual check, eliminating in-service maintenance costs in the offshore environment where the installation of reliable low maintenance equipment is essential.
