Wind cup wind vane

Wind vane

A wind vane is an instrument for determining the direction of the wind. It is generally installed on a pole about 10 meters high from the ground in an open area. Under the action of wind pressure, the arrow of the wind marker indicates the direction of the wind. A weather vane is basically an asymmetrically shaped object with a center of gravity fixed on a vertical axis. When the wind blows, the end that creates greater resistance to air flow will turn downwind, indicating the direction of the wind. The arrow of the wind vane always points to the source of the wind.

The shape of the wind vane can be divided into four parts: tail wing, balance hammer, pointing rod and rotating shaft. Wind speed and direction are measured using a magnetically sensitive wind speed cup and a wind vane respectively. The magnetic cup usually has three symmetrical cups, fixed on a vertical axis, so that the diameter surface of each cup is vertical.

Enhanced wind vane is used to indicate the wind direction. RY-FX-01 enhanced wind vane is composed of four parts: arrow tail, moving rod, main rod and base. The main part is made of high-quality stainless steel material with strong corrosion resistance, and the moving rod part is made of high-quality double stainless steel waterproof bearing with high sensitivity, small starting wind speed and durable. The products have the characteristics of easy installation and convenient transportation, and are widely used in meteorology, chemical industry, mining area, agriculture, oil field exploration and other industries.
