PC-Equipped
Anemometer/Wind Vane Systems
Komatsu Factory Co.'s PC-ready anemometer/wind vanes are the perfect tool to bring wind speed and direction data to a personal computer. With a basic system, a propeller-type sensor is linked to a translator, which converts the RS-422 digital signal output by the sensor to an RS232C signal. The signal is then transmitted to a personal computer, which calculates instantaneous and 10-minute average values for wind speed and direction and displays the results on-screen. The computer can use the 10-minute average values to generate and display or print daily or monthly charts and wind roses. Systems with additional features are easily configured by including a data logger, a modem, or other modules.
The easy-to-operate processing application is supported by Windows98, Me, NT, and 2000.
As an optional function, Komatsu Factory Co. has also developed an information release system that connects via Web and mail servers to use the Internet.
