Working Principle
The propeller wind speed sensor calculates the wind speed by measuring the driving force of the wind on the propeller. Its core components include propellers, magnetic steel rotors, induction components and processing circuits. The specific work flow is as follows:

1、Wind drive:
The propeller blades are subjected to wind pressure, resulting in torsional torque, which makes the blades rotate.

2、Magnetic pulse generation:
The rotation of the propeller drives the magnetic pulse generator on the shaft to rotate, resulting in a changing magnetic field.

3、Electromagnetic induction:
Using the principle of electromagnetic induction, a changing magnetic field generates an induced voltage or current in an induction element (such as a Hall element or induction coil), and the signal is proportional to the wind speed.

4、Signal processing:
The analog signal output by the induction element is processed by the processing circuit and converted into a square wave signal whose frequency is proportional to the wind speed for subsequent use or display.

For the measurement of wind direction, the propeller type wind direction sensor usually adopts the photoelectric or resistive principle. For example, the photoelectric wind direction sensor uses gray code encoding and photoelectric sensing technology to determine the wind direction by detecting the position of the mark on the rotating part; The resistive wind direction sensor uses a structure similar to the sliding rheostat, and calculates the wind direction by measuring the resistance change of the sliding rheostat.

Characteristic

1、Wide measuring range:
Propeller wind speed and direction sensor has a wide measuring range, suitable for different wind speed and direction measurement needs.

2、Stable and reliable operation:
The sensor has a simple structure, stable operation, and can operate reliably for a long time under harsh environmental conditions (such as strong winds, rain, snow, hail, etc.).

3、Strong gust resistance:
The propeller-type design enables the sensor to resist the impact of strong wind gusts, reducing measurement errors caused by changes in wind pressure.

4、Marine climate resistance:
The sensor housing and internal components are usually made of corrosion-resistant materials and can operate in Marine climate conditions for a long time without damage.

5、Easy maintenance:
The sensor is compact and easy to install and maintain. It is easy to clean, calibrate and replace parts when needed.

Application Area

1、Meteorological monitoring:
Used for monitoring wind speed and direction of meteorological stations, meteorological observation stations and other places.

2、Environmental monitoring:
Real-time monitoring of wind speed and direction in environmental monitoring stations, nature reserves, forest fire prevention and other fields.

3、Transportation:
In Bridges, tunnels, ports and other transportation facilities for wind speed monitoring and early warning.

4、Energy development:
In the field of wind power generation, it is used for wind speed and direction monitoring of wind turbines to improve power generation efficiency and safety.
