WS425 WINDCAP® Ultrasonic Wind Sensor
	Provides the most accurate and maintenance free wind measurements for demanding applications. Ideal for replacing mechanical sensors. Measures wind speed and direction from the smallest breeze to hurricane force gales (0...65 m/s), including gusts Superior data availability and accuracy in all wind directions due to the patented three transducer layout Analog, RS-232, RS-422, RS-485 and SDI-12 outputs No moving parts: virtually maintenance free Stainless steel construction Heated model available US National Weather Service relies on Vaisala ultrasonic technology
