WindSpeed Sensor Product Description
The Global Water WindSpeed Sensor is constructed of high-impact materials, ensuring its durabilityand ruggedness even in severe weather conditions. The wind speed indicatorhas a very low threshold, and it responds accurately to subtle changes in windspeed. The wind speed transmitter is molded to 25 of marine gradecable, with lengths up to 500 available upon request. The wind speedsensor’s output is 4-20 mA with a two wire configuration. The wind speedtransmitter’s electronics are completely encapsulated in marine grade epoxywithin a rubber sleeve.
Global Water’s PC300 Wind Speed Alarm and Controller uses the Wind Speedsensor’s output to trigger motors and alarms. In addition, Global Wateroffers the GL500 Wind Speed Recorder, which adds recording capabilities to theWind Speed indicators. The GL500 Wind Speed Recorder connects to theanamometer’s 4-20mA output to record data.
Why Measure Wind Speed?
Wind speed is an important weather parameter to monitor and record for manyapplications including meteorology, aviation, shipping, insdustry, construction,and many more. Some of the more common applications are for predicting andsupporting weather forcasts, determining the saftey of operating mechanicalequipment like cranes and lifts in industry, estimating the efficiency ofoperating power generating wind farms, navigation and safe operation in theshipping industry, aircraft safety, wastewater and landfill odor control, andothers.
Wind Speed is caused by air pressure gradients or the regions between weatherfronts, air moves in the direction of the low pressure system. The steeperthe gradient the stronger the wind. Additionally, wind speed is determinedby many other factors including the Coriolis effect, friction, and landtopography. Wind speed is typically reported in meters per second or milesper hour in the United States. For the shipping or boating industry windspeed can be reported in knots (a knot equal to one nautical mile per hour orapproximately 1.15 miles per hour or approximately 0.5 meters per second).
