WindSensor P2546D-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 P2546D-OPR (electronic version) features permanent magnets mounted on the shaft that activates an electronic switching circuit. This generates an open collector output signal with a frequency proportional to the wind speed.
Please consider the P2546D-OPR as a direct replacement for the discontinued P2546A-OPR. See technical note for replacing the P2546A-OPR reed switch version.
We also offer the P2546C-OPR coil version.

- Durable construction with anodized aluminum and stainless steel
- Low threshold speed
- Short distance constant
- Negligible overspeeding
- Angular response independent of wind speed
- Fully tested temperature performance
- Symmetrical geometry
- No external power source
- MEASNET calibrated
