5. Overview
The P2546A-L cup anemometer is a sturdy device that senses wind speed with
a three-cup rotor assembly (see FIGURE 5-1). Permanent magnets mounted on
the shaft cause a switch to close and open two times per revolution. The switch
has no bounce, and is equipped with a special mechanism that reduces the
variation in operating time over the frequency range. This feature facilitates
obtaining instantaneous wind speed by measuring the time interval of each
revolution.
