WindSonic 75 is a robust, low cost ultrasonic wind sensor with no moving parts. This 2-axis ultrasonic wind sensor offers maintenance-free wind speed and direction monitoring for true ‘fit and forget’ wind sensing.

The Gill WindSonic is a genuine low cost alternative to conventional cup and vane or propeller wind sensors, with all of the advantages of solid-state ultrasonic technology. With no moving parts to jam, break or wear out, this ultrasonic wind sensor is ideal for use in harsh weather conditions.

WindSonic 75 is a 2-axis ultrasonic wind sensor, providing wind speed and direction data via one serial or two analogue outputs. To confirm correct operation, wind sensor outputs are transmitted together with an instrumentation status code.

WindSonic 75 has been designed as a lightweight (0.5 kg) and robust ultrasonic wind sensor, with a corrosion-free polycarbonate construction. With a true solid-state construction, WindSonic 75 can be operated in harsh environmental conditions without fear of damage often associated with fragile cup or propeller wind sensors.

WindSonic 75 is suitable for a wide range of wind monitoring applications, particularly suited to marine & offshore (ships, data buoys) and land based installations. With a corrosion free exterior and no moving parts, this ultrasonic wind sensor eliminates the need for expensive on-site maintenance, particularly in remote locations where access is difficult.
