The RainWise^® WindLog

Wind Data Logging Device

The WindLog™ is a compact, inexpensive wind data logger, designed to meet the needs of people considering the purchase of a wind turbine. While many people rely on wind maps to assist them with this purchase decision, these maps don’t provide the detailed information for a specific area. The WindLog allows you to make your own accurate wind study to optimize your turbine placement and its performance, once installed.

Data can be downloaded from the WindLog using a 15-foot USB cable and the no-cost Windows-based WindLogger software (WindSoft™), which uses a SQLite database to track and record wind information. The logging interval can be set from once a minute to once an hour. USB extenders can be used to lengthen the USB cable to over 100 feet. The USB cable can be left connected to the WindLog allowing real-time viewing of the wind data on a computer. By combining both logged and real-time data WindLog can be used both online and offline. WindSoft can generate statistics, graphs and reports. It can also export CSV files for use with Microsoft Excel or any other application that supports CSV files.

Battery life for the logger will depend upon the environment and logging rates. Typical battery life is 6-9 months. When connected to a computer the WindLog will use the USB port power to run. This further extends the life of the batteries.

The Mini-Aervane wind sensor is equipped with low friction race bearings. This reduces the threshold to approximately one mile per hour. The wind direction sensor has a 16-point resolution. Logged direction readings are averaged readings.

A support mast is included with the WindLog. This mast can be used with the Rainwise® Mono Mount or tripod. The mast may also be attached to a support structure using U-Bolts or lag screws.

Wind Log Data Logger

Optional Accessories:

The USB extender provides up to a 100-foot extension of the WindLog USB connection. The USB signals are transmitted over standard CAT5e network cable.

The upper interface is housed in a waterproof enclosure. A three-foot USB cable connects the interface to the Windlog. A CAT5e network cable then connects to the second interface that in turn connects to a PC. The Windlog is powered through this connection when a computer is attached.

The WindLog wind sensor is connected to the data logger using 8-conductor cable. This 50 foot Ethernet cable can be used to separate the wind sensor from the WindLog.

Quick and easy to install.
Allows the wind sensor to be mounted higher up with easy ground level access to the data logger.
Available in 50 & 100 foot lengths.
