This version, the P2546C-OPR (coil version), features permanent magnets mounted on the shaft that induce a sine wave voltage inside a coil. This produces an output signal with frequency proportional to wind speed.
We also offer the P2546A-OPR coil version click here for more information on this version.
P2546-OPR features
One-piece rotor anemometer head
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
The cup anemometer is supplied with a Measnet calibration certificate and is fully compatible with all the data loggers manufactured by Kintech Engineering including the EOL Zenith and Orbit 360.
