The Met One 034B wind speed and direction sensor combines both wind measurements into a single sensing unit. The unit installs in minutes and will provide accurate, long term, continuous monitoring in hostile environments.
The sensor is designed to operate within a temperature range of -30° to +70° C and with wind speeds up to 167 mph. Wind speed is measured using a sealed reed switch which provides a series of pulses at a rate proportional to wind speed. Aluminum cups are used for durability and strength. Wind direction is measured using an aluminum vane directly coupled to a precision potentiometer. Variations in wind direction produce a corresponding change of voltage, which lends itself to both digital and analog measurement systems.
