Model BKC-ANM
Wind Speed & Direction Sensor
Rugged. Accurate. Hurricane-ready.
Overview
BKC-ANM combines wind speed and wind direction sensors in one durable package. It is built with heavy-duty components designed to withstand hurricane-force winds, yet light enough to register the softest breeze. Range and accuracy are verified in a wind tunnel.
Sealed long-life bearings and integrated drip rings eliminate icing problems around moving joints.
Speed 0.5 to 89 m/s
Direction accuracy ±3°
-40 °C to +65 °C
CE certified
