WindSensor P2546A-OPR Cup Anemometer
Overview
DISCONTINUED
The WindSensor P2546A-OPR Cup Anemometer has been discontinued and is no longer available for purchase. Please use the P2546D-OPR electronic version as a direct replacement. See technical note for replacing the P2546A-OPR reed switch version.
We also offer the P2546C-OPR coil version.
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 P2546A-OPR (reed switch version) features permanent magnets mounted on the shaft that activates a reed switch contact. This generates a potential free switch signal with a frequency proportional to the wind speed.
P2546-OPR features

- 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
