3-Cup Anemometer

12102

The 3-Cup Anemometer measure horizontal wind speed. This Wind Speed Instrument is sufficiently sensitive for detailed wind speed studies yet rugged enough to remain exposed for extended periods with minimum maintenance.
The 3-Cup Anemometer has light-weight hemispherical cups made from injection molded UV resistant polypropylene. The standard anemometer employs a DC tach-generator coupled to the cup wheel shaft. Cup wheel rotation produces a DC voltage which is directly proportional to wind speed.
The anemometer uses low torque stainless steel precision grade ball bearings for low starting threshold.
The 3-Cup Anemometer is supplied with a single mounting bracket which threads onto 3/4″ standard pipe.
Electrical connections are made via a connector at the bottom of the instruments. A variety of devices are available for signal conditioning, display, and recording.
