Configuration Options

The 40C was one of the first anemometers designed exclusively for the wind industry.

The 40C Anemometer has recorded wind speeds of 96 m/s (214 mph). Their bearings and low moment of inertia permit very rapid response to gusts and lulls. Due to their output linearity, these sensors are ideal for use with various data retrieval systems. A four-pole magnet induces a sine wave voltage into a coil, producing an output signal with frequency proportional to wind speed.

Constructed of rugged Lexan cups, the 40C is molded in one piece for repeatable performance. A rubber terminal boot is included with each anemometer for additional protection from the elements.

A MEASNET calibration certificate is available for each sensor: Download Calibration Report.
