S-WDA-M003 Wind Direction Smart Sensor

Overview

A research-grade, plug-and-play sensor that provides average wind direction for the measurement interval. This highly durable wind vane has a drip lip to prevent ice formation. Its shielded stainless steel ball bearings and static-dissipative housing provide long sensor life. The sensor calculates a unit vector average of wind direction, providing data directly in degrees.

NOTE: An M-CAA Full Cross Arm or M-CAB Half Cross Arm is required for mounting.
