VT-SA3E Ultrasonic Wind Sensor
0-70m/s IP65 ASA Weatherproof Anemometer
VT-SA3E wind speed and direction sensor uses the flight time difference of ultrasonic waves in the air to measure wind speed and direction simultaneously. Equipped with a low power consumption chip, it is ideally suited for solar- or battery-powered installations.
Product Overview
Constructed from molded thermoplastic ASA, the VT-SA3E exhibits high outdoor weatherability with extreme resistance to UV radiation, frost, and high temperatures (-40°C to +70°C). Featuring IP65 environmental protection and an ultra-low power draw (< 15 mA typical), it is widely deployed across weather observation, offshore buoys, port operations, agricultural monitoring, and wind energy installations.
