Product Introduction

Sensor for measuring wind direction at low power consumption, also available in a heated version (model DVR), 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 winds (up to 300 km/h), easy to interface with any data logger. The sensor uses a special high-precision potentiometer that provides excellent resolution, high sensitivity and a remarkable mechanical durability with an operating angle of 360 °. The sensor is equipped with electrical protections and is available with various signal outputs.
