FEATURES & BENEFITS
• Superior low starting threshold due to small physical size
• No plastic parts for extremely long life
• Precision stainless steel bearings for stability and repeatability
• Crossarm included with purchase of matching wind direction sensor
• Easy installation and maintenance
• Over 5 years in production
• Lightweight and rugged anodized aluminum exterior
INSTALLATION & MAINTENANCE
Installation consists of threading the 10-32 mounting base into our crossarm or any other suitable beam. If a
crossarm is used, the entire unit can be bolted to a mast or attached via U-bolts.
The sensor is dynamically calibrated at the factory and due to the nature of its operation should not require field
calibration. Field maintenance should include occasional cleaning of the cup assembly and inspection of the internal
mechanism to make sure it is free from insects and debris. In some applications users may need to occasionally
verify and document sensor accuracy with a synchronous test motor. Other possible routine maintenance is to
replace the bearing housing assembly every three to five years to maintain low starting threshold.
