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 dont 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.
- 2 MB of Flash memory stores over a years worth of wind
- Operates on 3 AA Alkaline or Lithium batteries.
USB power when connected to a computer.
- USB port provides fast
- 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.
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
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.
- 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.
generate statistics, graphs and reports. It also can export CSV files
for use with Microsoft Excel or any other application that supports CSV
The WindLog ships with a 15 foot USB cable. This is the
maximum standard USB cable length. A USB extender is available that will
allow you to extend this cable to 100 feet using CAT5e network cable.
support mast is included with the WindLog. This mast can be used with
the Rainwise Mono Mount, and tripod. The mast may also be attached to a
support structure using U-Bolts or lag screws.
