Quantity

Overview

The Gill WindObserver IS is an intrinsically safe ultrasonic wind sensor specifically designed for accurate and reliable wind measurement in hazardous or explosive environments. Built with 316 stainless steel and certified to ATEX and IECEx standards, it provides safe operation in areas such as offshore platforms, petrochemical sites, and industrial zones with flammable gases. The sensor measures both wind speed and direction with no moving parts, reducing maintenance needs and improving long-term performance. With its IP66-rated housing, optional heating system, and digital output options like RS422 and RS485, the WindObserver IS delivers dependable data in extreme weather and safety-critical applications. It is the ideal choice for industries that demand durability, precision, and explosion-proof certification in one compact device.
