The Heavy Duty Wind Direction sensor has been specifically designed for use in remote, unattended monitoring applications where the sensor is likely to encounter high winds and heavy icing conditions.

• Low starting threshold of 1.5 mph
• Unique "Mechanical Average System" reduces sensor wear
• Built in alignment and calibration fixture
• Operation in winds of 150 mph and ice loads of 2 inches

The two part wind vane is connected by a unique 10 slotted shaft coupler to a precision wire wound potentiometer.  The sensor output is an accurate mechanical average of the wind direction.  An additional benefit of the slotted shaft coupler is decreased potentiometer wear and greatly increased sensor life. It also includes an orientation fixture which facilitates accurate field alignment. For less harsh conditions see Standard Wind Direction Sensor.
