Ultrasonic anemometer

March 2005 Sensors & Transducers

The Young Model 85000 Ultrasonic Anemometer is a 2-axis, no-moving-parts wind sensor. It is suitable for general meteorological applications requiring accurate, reliable wind measurement. The sensor features durable, corrosion-resistant construction with opposing pairs of ultrasonic transducers secured in a streamlined moulded frame. The 85000 is wind tunnel tested and calibrated to provide accurate wind measurement over a wide operating range.

The standard sensor offers a variety of useful output options. Analog voltage outputs are provided for wind speed and wind direction. A variety of serial output formats are also available on the standard sensor. These include ASCII text, RMYT (compatible with YOUNG displays), NMEA and SDI-12 formats. The sensor installs on 1-inch (IPS) pipe. Wiring connections are made in a convenient weatherproof junction box; special connectors and cables are not required.
