Three-Cup Anemometer Rotor, 150 mm, Black ABS
Replace a matching wind-cup assembly without assuming you need an entire weather station. This black three-cup rotor is a component for a compatible anemometer shaft. It is for weather-station owners who can compare the hub and dimensions with their existing equipment.
- ✅ Replace the cup assembly as a component — The separate rotor lets you assess the moving cup part independently from the sensor body.
- ✅ Compare the fit before ordering — The open central hub is visible for checking against an existing shaft arrangement.
- ✅ Plan space around the rotor — The stated overall span helps you assess clearance from surrounding equipment.
- ✅ Keep the purchase focused — One three-cup assembly is supplied rather than a complete weather-station installation.
A cup assembly for a matching anemometer
The product photographs show a cup rotor with a hollow centre hub. Installed weather stations are application examples; the pictured sensor bodies, cables, masts and brackets are not part of this rotor assembly. It does not provide a numerical wind reading on its own.
Compare the approximately 150 mm span and 62 mm height with the existing assembly. Shaft diameter, fixing specification and named weather-station compatibility are not confirmed, so do not assume interchangeability from the appearance alone.
The three cups form the rotating part of a suitable wind-speed system. A wind-direction function, electronic output, power requirement and measurement range are not established for this component. Keep the existing sensing system's requirements in mind when choosing a replacement.
The standalone item is the black three-cup rotor; complete stations below are installation examples.
The sensor body, arm and mast illustrate a possible installation and are not supplied with the rotor.
Use only with a mechanically compatible anemometer assembly.
Inspect the hollow hub against the existing shaft and fixing arrangement.
Three cups form the moving rotor assembly.
The cup shape belongs to the rotating part, not a separate direction vane.
Check the centre fixing details before choosing a replacement.
Allow for approximately 150 mm overall span and 62 mm height.
