Model WN37, WNZ37, WMSC37 - Anemometers
Wind gauges WN37 and WNZ37 measure the east/west and north/south wind components, allowing the calculation of horizontal wind velocity. The WNZ37 measures the vertical component of wind as well. If only wind speed (and not wind direction) is of interest, then the WMSC37 cup anemometer is the most suitable instrument for your application. As the propellers or cups revolve, the rate of rotation is measured using high frequency initiators which allow operation free of both direct contact and feedback effects. As a result, the sensors respond very sensitively to the slightest air movements.
