Wind

Anemometer to measure the wind speed and the wind direction

Wind Speed Sensor, Heavy Duty Design

TF4035

The wind speed sensor type 4035 serves for transmission of electrically measured values of the wind speed. It is designed for operation in meteorology and environmental protection, e.g. automatic weather stations, at airports, on research vessels, at industrial sites, for mobile measuring systems etc..The instrument’s rugged construction and its dust- and water repellent surface, as well as the optional high performance heating enable heavy duty applications like wind energy measurement or operation under severe climatic conditions. Thanks to various simultaneously usable outputs and further options it is suitable for a wide range of measuring tasks (refer to “ordering code”).
