Wind Speed and Wind Direction Sensors

Wind direction is indicated by a wind vane or electronic wind direction sensor. Advanced systems like the HazMet-100 use a built-in electronic compass and GPS for automatic north-alignment, eliminating the need for manual orientation. These sensors output compass-bearing wind direction data continuously for use in safety, compliance, and forecasting applications.

Wind direction is measured by a wind vane in traditional setups, or by electronic meteorological sensors in modern applications. OSI's multi-parameter sensors measure wind direction alongside wind speed, temperature, humidity, and barometric pressure, providing comprehensive atmospheric data for aviation, emergency response, and industrial environmental monitoring.

Ships typically use electronic anemometers and wind vanes integrated into their bridge navigation systems to measure wind direction. For maritime and offshore applications, robust optical or ultrasonic sensors are preferred due to their no-moving-parts design and resistance to harsh marine environments. OSI's optical sensors are well-suited for such demanding deployments.

A long-baseline optical anemometer, such as the OSI LOA-005, measures path-averaged wind speed and turbulence across distances ranging from 100 meters to over 10 km using optical scintillation technology. Unlike point sensors that capture data at a single location, long-baseline sensors provide spatially averaged measurements that are more representative of actual atmospheric conditions across large areas.

No. OSI's DSP-based optical sensors require no field calibration. The AGC circuitry automatically compensates for LED output variations, contaminated optics, and dusty air conditions. Preventative maintenance is minimal — typically a window cleaning and optical alignment check every six months — making these sensors ideal for remote or difficult-to-access installations.

OSI wind sensors serve aviation (FAA-certified AWOS systems), industrial fenceline monitoring at refineries and chemical plants, aluminum smelter emissions compliance (EPA Method 14), emergency hazmat response (EPA ALOHA-compatible), environmental research, wind energy optimization, and government agency deployments including NASA, NOAA, and the U.S. military worldwide.
