Calibration accessories for wind sensor
RM Young Wind Sensor Calibration Accessories are not a replacement for laboratory or wind tunnel calibration. However, the accessories offer an effective means of regular field checking of your Young wind sensors.
The Model 18802 Anemometer Drive provides a convenient and accurate way to rotate an anemometer shaft at a known speed. The motor rotates clockwise or counterclockwise at a selected speed between 200 and 15,000 rpm. The LCD display is referenced to an accurate quartz time base. For portable operation, the unit runs on internal batteries. An AC wall adapter is included.
The Model 18811 Anemometer Drive is identical to the Model 18802 except that the drive motor incorporates a gear reducer for operation in the range of 20 to 990 RPM in 10 RPM increments. The lower range is recommended for cup anemometer calibration.
The Model 18112 Vane Angle Bench Stand is used for calibrating wind direction sensors in the wind direction peak. An easy-to-read marker indicates 0 to 360 degrees with 1/2 degree resolution.
Model 18212 Vane Angle Fixture – Tower Mount similar to Model 18112, the tower mount feature allows use on the tower as well as on the bench top.
The Model 18310 Propeller Torque Disc controls the anemometer’s pitching torque with a simple yet accurate check/error check.
The Model 18312 Cup-Wheel Torque Disc controls the cup anemometer’s tilting torque.
The Model 18331 Vane Torque Gauge checks vane bearing torque for wind monitor sensors. Slide the fixture over the main housing and make simple but accurate vane torque measurements.
The Model 18301 Vane Alignment Rod assists in visually aligning a wind vane to a known directional reference during installation.
