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.

Maintenance Instructions
1. Perform visual inspection every 3‑6 months: Clean marine biological attachments, salt crust, dust on black
propeller and large‑area white wind vane. Rinse gently with fresh water, do not use hard brush to avoid
scratching surface.
2. Manual rotation test: Spin black propeller and white wind vane by hand; rotation should be smooth without
jamming or abnormal noise.
3. Inspect marine‑grade pigtail cable regularly, check cable surface crack and joint water seepage; seal cable
joint additionally for permanent marine installation.
4. Ceramic bearing is maintenance‑free. **Do not add grease**, extra grease will absorb salt‑dust and cause
rotation stuck. Only clean surface dirt.
5. Check propeller and white wind vane for aging, crack or deformation. Replace spare parts once deformation
appears; deformation will bring obvious measuring deviation.
6. Complete full inspection after typhoon or heavy storm. Replace bearing or potentiometer spare parts if rotation
response becomes sluggish.
7. Keep original mark of orientation ring during disassembly, so there is no need for wind‑direction recalibration
after reinstallation.

Spare Parts List
1. Black six‑blade helical propeller assembly
2. Large‑area white balanced wind vane assembly
3. Propeller shaft ceramic bearing core kit
4. Internal 10KΩ conductive plastic potentiometer module
5. Marine‑grade sealed pigtail cable6. Mounting orientation ring & stainless‑steel clamping set
> Note: Please mark model 05106‑MA when ordering spare parts.

Acceptance Standard
1. Visual check: Black propeller, large‑size white wind vane and housing are free of crack, dent, deformation and
corrosion. Fasteners and cable are complete.
2. Mechanical test: Rotate propeller and wind vane manually, full‑range smooth rotation without stuck point;
orientation ring mark intact.
3. Electrical test: Apply rated excitation voltage. Rotate white wind vane, potentiometer output voltage changes
continuously with azimuth. Spin black propeller, AC pulse signal outputs normally.
4. Mount dimension: Confirm fitting for 34 mm OD 1‑inch standard mounting pipe.
5. Accessories check: Confirm cable, mounting clamp and orientation ring match order list.

FAQ
Q1: What is the function of large‑area white wind vane on 05106‑MA?
A: The large‑size balanced white wind vane is wind‑direction sensing component. It catches airflow and points to incoming‑wind direction, provides sensitive wind‑direction tracking performance even under low‑wind speed.

Q2: Can 05106‑MA run continuously on ship under salt‑fog condition?
A: Yes, it is MA marine‑optimized edition, with anti‑corrosion ceramic bearing and UV‑resistant housing. We recommend extra waterproof sealing for field cable joints.

Q3: What signal outputs come directly from 05106‑MA? Do I need signal‑conditioning module?
A: Raw signal: AC sine‑wave for wind speed; potentiometer analog voltage for wind direction. If your data logger / PLC can not read such signal, optional signal‑conditioner module is required to convert to 0‑5V or 4‑20mA.

Q4: Does 05106‑MA need regular bearing greasing?
A: Ceramic bearings are maintenance‑free. Grease application is forbidden. Grease will trap salt dust and cause rotation jam. Only clean surface contaminants.

Q5: Is 5° electrical dead‑zone of wind‑direction a product defect?
A: Not defect. Mechanical rotation is full 360°, but potentiometer itself has a small 5° non‑reading zone, which is inherent design feature of this sensor.

Q6: What maximum wind speed can 05106‑MA withstand?
A: Measuring range up to 100 m/s, suitable for typhoon extreme strong‑wind monitoring.
