What is the purpose of the weather vane?

A weather vane can be used to determine the wind direction. Widely used in meteorology, chemical industry, mining industry, agricultural production, oil field exploration, wind power generation and other industries, with the characteristics of simple installation and convenient transportation. A weather vane is an asymmetric object whose center is fixed on a vertical axis. When the wind blows, the end with great resistance to the airflow will rotate with the wind to show the wind direction.

When the wind blows, the end with great resistance to the airflow will rotate with the wind to show the wind direction.

The sensors of wind vane (wind speed sensor) are code wheel and photoelectric module. When the wind vane rotates with the change of wind direction, the shaft drives the code wheel to rotate in the gap of the photoelectric module, and the generated photoelectric signal corresponds to the gray code output of the current wind direction. The transducer of the sensor can adopt a precision conductive plastic potentiometer, thus generating a variable voltage signal output at the movable end of the potentiometer. The metal wind vane consists of six parts: wind vane, wind wheel, tail wing, movable rod, main rod and base. The main part is made of high quality stainless steel; The blades are made of high-quality engineering plastics with strong corrosion resistance; The moving rod adopts high-quality double stainless steel waterproof bearing, which has high sensitivity, low starting wind speed and durability.
