WindSensor P2546C-OPR Cup Anemometer
Overview
The WindSensor P2546-OPR Cup Anemometer combines unrivaled performance with the only IEC 61400-12-1 compliant classification on the market. Originally designed for marine environments, the P2546-OPR is ideally suited for wind resource assessment and power performance studies both onshore and offshore.
The P2546C-OPR (coil version) features permanent magnets mounted on the shaft that induce a voltage in a coil. This generates a sine wave output signal with a frequency proportional to the wind speed.
We also offer the P2546D-OPR electronic version.
