The NRG Systems IceFree Ultrasonic Wind Sensor is designed for turbine control applications, and carries a 240 W heater in a rugged aluminium body for all weather conditions.

Two additional models are polycarbonate – suitable for turbine control in moderate climates or wind resource assessment.

“We are pleased to offer a comprehensive line of ultrasonic sensors,” says Laura Goodfellow, Technical Sales Account Manager for NRG Systems. “They provide real-time, accurate data, and have no moving parts for minimal maintenance. By pairing ultrasonic and mechanical sensors for turbine control, wind farm operators can ensure redundancy and benefit from both technologies.”
