The Global Water Wind Direction Sensor is designed to accurately measure wind direction even in the harshest environments. The wind direction transmitter is molded to 25 ft of marine grade cable, with lengths up to 500 ft available upon request. The wind direction sensor's output is 4-20 mA with a two wire configuration. The wind direction transmitter's electronics are completely encapsulated in marine grade epoxy within a rubber sleeve.
Global Water's PC320 Wind Direction Alarm and Controller uses the Wind Direction sensor's output to trigger motors and alarms. In addition, Global Water offers the GL500 Wind Direction Recorder, which adds recording capabilities to the Wind Direction transmitter. The GL500 Wind Direction Recorder connects to the wind direction sensor's 4-20mA output to record wind direction data.
Why Measure Wind Direction?
Wind speed is an important weather parameter to monitor and record for many applications including meteorology, aviation, shipping, insdustry, construction, and many more. Some of the more common applications are for predicting and supporting weather forecasts, determining the safety of operating mechanical equipment like cranes and lifts in industry, estimating the efficiency of operating power generating wind farms, navigation and safe operation in the shipping industry, aircraft safety, wastewater and landfill odor control, and others.
Wind Direction is caused by air pressure gradients or the regions between weather fronts, air moves in the direction of the low pressure system. Additionally, wind direction is determined by many other factors including the Coriolis effect, friction, and land topography. Wind direction is always given as the direction the wind is coming from. For example a wind out of the east is given as an east wind, or wind direction or 90 degrees.
