風向標風向測試機小型風向測量機風向風速測試機

Small wind vane wind instrument measuring wind direction and wind speed measuring instrument

型號:G81186

Model: G81186

（小型）測風向，風是由許多小尺度的脈動，疊加在大尺度規則氣流上的三維矢量。但在氣象學上，卻把空氣的水平移動叫作風，即把它作為二維矢量來考慮。由兩個參數來確定，即風速（風矢量的模數）和風向（風矢量的幅角）。

(small) measure wind direction, wind is composed of many small scale fluctuation, the three-dimensional vector in the large scale flow on the superposition rule. But in meteorology, but the horizontal movement of air is called style, which is considered as a two-dimensional vector. By two parameters, namely wind speed (modulus of wind vector) and wind (wind vector argument).

GZYK9X風向標用來測量近地風向、風速，廣泛應用於氣象、海洋、環境、農業、水利、電力、軍事、科研、文物保護等領域。

The GZYK9X indicator used to measure wind direction, wind speed near the ground, widely used in the field of meteorology, marine, environment, agriculture, water conservancy, electric power, military, scientific research, cultural relic protection.

三杯式風傳感器工作原理：

Three cup type wind sensor principle of work:

光電型的風向傳感器采用低慣性輕金屬的風向標響應風向，帶動同軸碼盤轉動，此碼盤按格雷碼編碼並以光電子掃描,輸出對應風向的電信號。

The wind direction sensor photoelectric type with low inertia of light metal wind vane response, drives coaxial disc rotation, the encoder according to the gray code and the optoelectronic scanning, electrical signal output corresponding to the wind.
