P2546A-L Anemometer
The P2546A anemometer is manufactured by Windsensor and cabled by
Campbell Scientific. Lead length for the P2546A is specified when the sensor
is ordered.
The P2546A's cable can terminate in:
• Pigtails that connect directly to a Campbell Scientific datalogger
(option –PT).
• Connector that attaches to a prewired enclosure (option –PW). Refer
for more information.
6. Specifications
Features:
• Calibration — The P2546A-L is shipped with a MEASNET
certificate containing information about where the anemometer was
calibrated, the calibration procedure used, the calibration equation
obtained, and the serial number of the anemometer.
• Quality — Constructed only of durable materials such as anodized
aluminum and stainless steel.
Compatibility
Dataloggers:
CR800 / 850, CR1000, CR3000, CR5000,
CR10(X), CR510, CR23X, 21X, CR7
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 m/s, 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 assures that the temperature influence
on the calibration is within the specified limit.
