Overview
#40C NRG Wind Speed Sensor (-55 to +60C) w/o Cable
NRG's #40C is a MEASNET-calibrated anemometer primarily intended for wind prospecting applications. A four-pole magnet induces a sine wave voltage into a coil producing an output signal with frequency proportional to wind speed. This signal is measured by our data loggers. The #40C is constructed of Lexan. A rubber terminal boot is included. In February 2008, the #40C replaced the #40 anemometer.
