The Davis 6410 Replacement Anemometer includes both wind speed and wind direction sensors. Rugged components stand up to hurricane-force winds, yet are sensitive to a light breeze. These Davis Vantage Pro2 anemometers for sale include sealed bearings for long life. The range and accuracy specifications of this Davis Instruments anemometer have been verified in wind-tunnel tests (information available upon request). A Davis Anemometer reported wind speeds of 175 miles per hour before its tower collapsed during hurricane Andrew, 1992. Digital filtering, with time constant as specified below, is applied to wind direction measurements. In areas where icing of the anemometer is a problem, the included Anemometer Drip Rings deflect water from the joint between moving parts. The Davis 6410 is compatible with Vantage Pro and Vantage Pro2. Includes 40' cable.
Wind-tunnel tested to withstand wind speeds in excess of 200 miles per hour!
Wind speed range: 1 to 200 mph, 1 to 173 knots, 0.5 to 89 m/s,1 to 322 km/h.
Sealed stainless steel ball bearings for long life.
Brass weighted wind vane for more accurate direction indication
Improved design without the troublesome reed switch.

Sensor Output
#Wind Direction
Display Resolution : 16 points (22.5°) on compass rose, 1° in numeric display
Accuracy: ±3°
#Wind Speed
Resolution and Units : Measured in 1 mph. Other units are converted from mph and rounded to nearest 1 km/h, 0.1 m/s, or 1 knot
Range: 1 to 200 mph, 1 to 173 knots, 0.5 to 89 m/s, 1 to 322 km/h
Accuracy: ±2 mph (2 kts, 3 km/h, 1 m/s) or ±5%, whichever is greater
Maximum Cable Length : 240' (73 m). Maximum wind speed reading decreases as length of cable from Anemometer to ISS increases. At 140' (42 m), maximum speed is 135 mph (60 m/s). At 240', the maximum is 100 mph.
Input/Output Connections:
Black: Wind speed contact closure to ground
Red: Ground
Green: Wind direction pot wiper (20KΩ potentiometer)
Yellow: Pot supply voltage
Wind Speed Translation Formula: 1600 rev/hr = 1 mph; V = P(2.25/T) (V = speed in mph, P = no. of pulses per sample period; T = sample period in seconds)
