Details
All boom extensions and adapters are made of durable galvanized steel. Both stub mast options come with hose clamps for mounting on any tower or boom up to 203 mm (8”) in diameter.
Each Boom Extension that comes standard with our 2.4m (95”) Side Mount Booms can also be purchased separately. Extension #9342 is for mounting NRG sensors, including the NRG 200M Wind Vane and NRG 40C Anemometer; extension #12264 is for mounting the NRG S1 Anemometer; and extension #9165 is for mounting the WindSensor P2546-OPR Anemometer. Each boom extension name includes the ratio between the diameter of the horizontal boom and the height the extension will position anemometer cups above the boom. For instance, “20D” indicates that the cups of a WindSensor P2546-OPR Anemometer will be positioned above the horizontal boom arm by an offset height that is 20 times the horizontal boom diameter when using a #9165 boom extension.
The Thies Adapter is a collar adapter that allows you to mount the Thies First Class Advanced Anemometer on any 2.54 cm (1”) diameter vertical pipe, such as NRG boom #4478 or any boom already fitted with a WindSensor boom extension.
The 16” Stub Mast is a straight stub mast that mounts vertically on our 2.87 m (113”) pipe booms to raise the sensor position 410 mm (16 inches) vertically.
The 13” Z Mast is an offset stub mast that mounts on our 2.87 m (113”) pipe booms to extend the sensor position 122 mm (4.8 inches) vertically and 239 mm (9.4 inches) horizontally.
