If you look carefully you will see that almost ALL the ultrasonic wind speed/direction sensors have four sensors mounted at the bottom of the sensor bouncing the ultrasonic signal off the top of the sensor. This means that the sensor has no idea of the boat heel angle and will give the wrong (lower) speed if the boat is heeled over. The CruPro UWDS10 wind speed/direction sensor has two ultrasonic sensors on the bottom and two at the top. This enables the mathematics to perform the correct wind speed and direction even if the boat is sailing at a heel angle.

The UWSD10 provides NMEA 0183 output of wind speed, wind direction and air temperature using four ultrasonic sensors configured in a 3 dimensional array. The UWSD10 has no moving parts to wear out.

The UWSD10 calculates wind speed with a resolution of 0.01 knots and works from zero wind speed to 120 knots. Wind direction is output in degrees and air temperature in degrees C.

The UWSD10 draws only .040 amps and is provided with a 30M cable and two waterproof connectors.

The UWSD10L draws only .0045 amps and is provided with a 30M cable and two waterproof connectors.

Each UWSD10 wind sensor is individually calibrated in our wind tunnel every 1 degree from 0 to 359 degrees and the errors mapped and compensated to provide the best accuracy possible as shown here:

The UWSD-10 Ultrasonic Wind Speed/Direction sensor is 100% compatible with the WSD-110 wind display (see www.cruzpro.com/wsd110.html).
