Wind speed and direction finder purpose and principle
Handheld instrument USES: wind speed and direction of wind speed measurement adopts microcomputer technology, can measure the instantaneous wind speed, the instantaneous wind scale average wind speed at the same time, high average wind scale and corresponding wave parameters. Handheld wind instrument with data latch function, easy reading. Wind part adopts the measurement refers to the device, without artificial to the north, simplify the measuring operation. Handheld wind instrument of small size, light weight, full functions, can be widely used in agriculture and forestry, environmental protection, Marine, scientific research in the fields of atmospheric wind parameters measurement. Handheld wind instrument working principle introduction: part 1, direction: by the vane and the direction of the wind scale ( Magnetic compass) And so on, the wind by wind pointer value for the location of the wind on the dial. Part 2, wind speed: handheld wind instrument adopts traditional three-ring rotating frame structure, the instrument inside the single chip microcomputer sampling, for the wind speed sensor's output frequency is calculated, after zui instrument output instantaneous wind speed, average wind speed, the instantaneous wind scale, one minute one minute average wind scale, average wind speed and wave height. Measured parameters on the liquid crystal display with digital display directly.
