P2546D-L Three-Cup Anemometer with MEASNET Calibration

IEC 61400-12 Class 1 performance, ideal for wind-energy applications

9 ₫

The P2546D, manufactured by WINDSENSOR, is a Class 1 cup anemometer commonly used in wind resource assessment and power performance applications. Each anemometer is individually calibrated compliant with IEC 61400-12-1 and is shipped with a MEASNET calibration certificate. The P2546D features permanent magnets mounted on the shaft that activate an electronic switching current. In response, this generates an output signal with a frequency that is proportional to the wind speed. The durable construction is suitable for both on-shore and off-shore environments. The “D” version of this sensor (electronic version) is compatible with all Campbell Scientific measurement and control data loggers.

Other available versions:

- P2546A (reed switch version)
- P2546C (coil version)

Sensor	3-cup anemometer
Measurement Description	Wind speed
Range	0 to 75 m/s
Starting Threshold	< 0.3 m/s
Starting Speed	0.27 m/s
Gain	0.6201 m
Distance Constant	λ₀ = 1.81 ± 0.04 m
Standard Deviation of Offset	0.014 m/s
Standard Deviation of Gain	0.027 m
Variation among Units	±1%
Non-Linearity	< 0.04 m/s
Temperature Influence	< 0.05 m/s (-15° to +60°C)
-NOTE-	The specifications are based on 80 wind tunnel calibrations performed according to the Measnet Cup Anemometer Calibration Procedure. The specified offset and gain figures represent the mean values of these calibrations. Variation among units designates the maximum deviation of any unit from the straight line representing these mean values. All units are run-in for 225 hours at 9 ms^-1, in order to reduce the initial bearing friction to a level close to the steady state value. After run-in, bearing friction is tested at -15°C and at room temperature. The allowed limits for this test assure that the temperature influence on the calibration is within the specified limit.
