The YOUNG Model 81000 Ultrasonic Anemometer is a 3-axis, no-moving-parts wind sensor. It is ideal for applications requiring fast response, high resolution and three-dimensional wind measurement.
The sensor features durable corrosion-resistant construction with 3 opposing pairs of ultrasonic transducers supported by stainless steel members. Each 81000 is individually wind-tunnel calibrated. Wind and sonic temperature data is avilable on four voltage output channels. Serial RS-232 and RS-485 outputs are available as well. The sensor installs on standard 1 inch pipe.
