Gill Instruments WindObserverIS intrinsically safe ultrasonic anemometer

The Gill Instruments WindObserver Intrinsically Safe ultrasonic anemometer is now certified by the International Electrotechnical Commission (IEC) for use in explosive atmospheres (Ex).

Gill has added IECEx to existing safety ATEX certification held for its anemometer, which can provide quality data and reliability.

The WindObserverIS provides accurate measurements of wind speed and direction and can be installed in hazardous and explosive atmospheres found in marine, offshore and other environments where significant quantities of flammable liquids, vapour and combustible dusts could cause fire or explosion.

The device measures wind speeds of 0-75 m/s and 0-359° wind direction in extreme environments, remains operational in temperatures from -30 to +70°C and provides low start-up speeds of 0.01 m/s. It has no moving parts, is lightweight and is constructed from stainless steel to provide durability with low maintenance requirements, making it suitable for long-term installations in areas where access is difficult. The device also features sophisticated error checking and fault reporting to ensure the quality of the reported data.
