t031 TVV

Wind Speed Transducer

TVV is composed of a rotating body connected to three conical shaped elements (cups), and it measures the wind speed exploiting the wind resistance to their circular movement. The rotating system is equipped with a six poles cylindrical magnet. A Hall effect sensor detects the rotational movement that generates in the meantime an impulse at the passage of each pole.
The dimensions of the cups and the lightness of its materials have been thoroughly picked to achieve a very low mechanical inertia and, consequently, to ensure a high sensitivity of the measurement.
The structure of TVV is very robust, the sensing element has a reliable durability and a proper resistance even at high wind speeds. Furthermore, its simple and compact design facilitates the installation and simplifies the on-site maintenance activities. The sensor is supplied with power and signal cable (12m), and it is available upon request on heated version, powered at 24V (alternating or direct current).
