Wind Speed Sensor Product Description

The Global Water Wind Speed Sensor is constructed of high-impact materials, ensuring its durability and ruggedness even in severe weather conditions. The wind speed indicator has a very low threshold, and it responds accurately to subtle changes in wind speed. The wind speed transmitter is molded to 25 ft of marine grade cable, with lengths up to 500 ft available upon request. The wind speed sensor’s output is 4-20 mA with a two wire configuration. The wind speed transmitter’s electronics are completely encapsulated in marine grade epoxy within a rubber sleeve.

Global Water’s PC320 Wind Speed Alarm and Controller uses the Wind Speed sensor’s output to trigger motors and alarms.  In addition, Global Water offers the GL500 Wind Speed Recorder, which adds recording capabilities to the Wind Speed indicators.  The GL500 Wind Speed Recorder connects to the anemometer’s 4-20mA output to record data.

Why Measure Wind Speed?
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 forcasts, determining the saftey 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.the total radiation or sum of the direct radiation and the diffuse solar radiation.

Wind Speed is caused by air pressure gradients or the regions between weather fronts, air moves in the direction of the low pressure system. The steeper the gradient the stronger the wind. Additionally, wind speed is determined by many other factors including the Coriolis effect, friction, and land topography. Wind speed is typically reported in meters per second or miles per hour in the United States. For the shipping or boating industry wind speed can be reported in knots (a knot equal to one nautical mile per hour or approximately 1.15 miles per hour or approximately 0.5 meters per second).
