RM YOUNG 05108-45 Heavy Duty Alpine Wind Monitor

WEATHER STATION The Wind Monitor-HD-Alpine has all the important features of the Heavy Duty unit that greatly extend the service life. It promises improved survivability for the most severe wind measuring applications. In addition, it has the benefit of a specially formulated, ice-resistant coating on the external surfaces to improve performance in harsh alpine condtions. The reliability of the Wind Monitor sensor is well known. The sensitive vane and propeller combination has proven effective for countless applications in many disciplines. The Wind Monitor-HD (Heavy Duty) model is designed to address the most common concern of mechanical wind sensors: bearing replacement.  The HD utilizes extremely long-wearing, oversize ceramic bearings to increase servcie life many times longer than standard stainless steel bearings. In addition to being more wear-resistant, ceramic is resistant to corrosion in environments that are hostile to steel bearings.  The Wind Monitor-HD also has oversized propeller shaft, high pitch propeller and stainless steel locking propeller nut, all features that will enchance long-term reliability of the sensor. The instrument mounts on standard 1 inch pipe. Features : Extremely long-wearing, oversize ceramic bearings to extend service Oversized propeller shaft Ice-resistant coating with all-black color scheme for harsh alpine conditions.
