RAINWISE WindLog Wind Data Logger & PC Software

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 do your own accurate wind study to optimize your turbine placement and its performance, once installed. Product details * 1 MB of Flash memory stores over a years worth of wind data. * Operates on 3 AA Alkaline or Lithium batteries. * Uses USB power when connected to a computer. * USB port provides fast downloads. * Free Windows software. * Logs average speed, wind gust and average direction. * User selectable logging intervals from 1 minute to 1 hour. The wind logger operates on three AA batteries. Battery life will depend on the environment and logging rates. Typical life should be around 6 months. Lithium batteries are recommended for cold environments. When connected to a computer the WindLog will use the USB ports power to run. This further extends the life of the batteries. SPEED Range: 0 – 67 meters per second ( 150 Mph) Accuracy: + / - 2% Sensor: 4-blade propeller – Lexan – UV inhibited Threshold: .45m/ sec. ( 1 Mph) Transducer: Magnetic dry reed switch Frequency: 1 cycle per revolution DIRECTION Range: 360° – no deadband Resolution: 22.5° , averaged. Accuracy: + / - 22.5° Sensor: Balanced vane with a 16.5cm ( 6.6 inch) radius Threshold: .9 m/ sec. ( 2 mph) at a 10° deflection. The balanced propeller is supported in stainless steel instrument ball bearings. The direction is obtained through 8 dry reed switches with no dead band. The M-AV sensor is made from UV inhibited Dupont Delrin, Lexan and stainless steel. The Mini-Aervane wind sensor is equipped with low friction race bearings. This reduces the threshold to approximately 1 mile per hour. The wind direction sensor has a 16-point resolution. Logged direction readings are averaged readings. WindSoft - Free Windows Software Package Each WindLog ships with a free Windows based application, WindSoft. The software uses a SQLite database to track and record wind information. While connected, WindSoft will update the database every minute. Downloaded data is integrated into the database. By combining both logged and real-time data the WindLog can be used both online and offline.
