The model 81000 is a 3-axis, no-moving-parts wind sensor. It is ideal for applications requiring fast response, high resolution and three-dimensional wind measurement. It measures three dimensional wind velocity and speed of sound based on the transit time of ultrasonic acoustic signals. Sonic temperature is derived from speed of sound which is corrected for crosswind effects. Environmental resistance is achieved by using UV stabilized thermoplastic, stainless steel, and anodized aluminum components.
