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.
