The Wind Data Logger is an affordable and easy-to-use tool for wind site evaluation and wind generator performance analysis. It records wind speed, time and date directly to a Secure Digital (SD) card to provide convenient data downloads. The logging interval is adjustable from 10 to 60,000 seconds (16.6 hours). The 2 gigabyte SD card (included) will store a year of data at 30 second intervals and many years of data at longer logging intervals. Common spreadsheet software (i.e. Microsoft Excel ™) can be used to view, graph, and analyze your wind data. Easy to use web-based software is provided. Simply upload the data and the software will automatically plot the data as well as provide basic statistics. A 16-character x 2 line backlit LCD screen displays current information and is used for configuring the data logger. A simple menu-driven interface using the LCD and three front panel buttons makes setup easy. A bright backlight makes the data logger easy to use at night. The DataLogger is housed in a waterproof enclosure.
The solar powered models work well for wind data logging in remote areas without access to AC power. The included 10-watt solar panel and sealed battery will run the data logger almost indefinitely. They come with a 10-watt PV module, a side-of-pole mount for the module, a charge controller, and a 7 amp-hour battery.
The AC model comes with a Universal AC power supply that accepts 90-264 VAC, 125-370 VDC, 47-63 Hz instead of a solar module and battery; however, it does have a space for a 8ea D Cell Alkaline Batteries for 30 day power backup (batteries not included).
The optional #40R anemometer is a more rugged, extra heavy duty version of the standard 3-cup anemometer. Both AC and DC models are housed in a weatherproof Pelican case with self-resetting fusing, and have lightning protection for all sensor channels and solar input.
