Product Description
The Gill MicroVane and 3-Cup Anemometer measure horizontal wind direction and wind speed. Sensitive enough for detailed wind studies, these sensors are rugged enough for permanent installation with only periodic maintenance.

The MicroVane has a balanced vane assembly which rotates on sealed stainless steel ball bearings. Vane angle is sensed by a precision conductive plastic potentiometer.

Output signal is a DC voltage proportional to vane angle. For maximum sensitivity, the Model 12002 and 12302 Microvanes employ a lightweight, highly responsive, expanded polystyrene (EPS) fin with a durable, UV resistant coating.

For greater durability, the 12005 and 12305 Models have a thin aluminum fin. Aluminum fin models are somewhat less sensitive than the EPS fin models. The 3-Cup Anemometer is constructed with lightweight, UV resistant plastic cups. Standard models utilize a sensitive DC tach-generator to measure wind speed.

An optional photochopper transducer produces a 10 pulse per revolution DC square wave. Output is linearly proportional to wind speed.

Models 12002 and 12005 combine a MicroVane and 3-Cup Anemometer with a 76cm mounting crossarm to minimize potential wake effects. An optional 28cm crossarm is available for special applications. All sensors mount on standard 1 inch pipe.
