VV1 Precision Wind Speed


Add to wishlist

Sensor 'First Class' to measure the wind speed at low power consumption also available in a heated version (model VV1R), compact and sturdy, made of aluminum alloy with anodized to protect against salt air and oxidizing agents.
Extremely linear and precise, with high dynamic response even in strong gusts, easy to interface with any data logger. The sensor uses specific arrangements including special self-lubricating bearings, which allow the MeasNet certification and make it ideal for Eolic monitoring applications (Wind power), guaranteeing maximum performance. The sensor is equipped with electrical protections and is available with various signal outputs.
