Wind Speed Sensor Current Type(4 to 20mA) Anemometer Kit (Waterproof & Industrial)

Product description

Do you want to build a device that can detect the direction and pressure of air in the atmosphere?

The Three Cups Type Wind Speed Sensor Current Type (4 to 20mA) Anemometer Kit is an instrument that can measure the wind speed. It consists of a shell, wind cups, and a circuit module. The circuit module integrates photovoltaic modules, industrial microcomputer processors, current generators, and other components.

The sensor shell and the wind cups are made of aluminum alloy with special mold precision casting technology. They have very small size tolerances and high surface precision. The internal circuit is protected from external factors. The sensor is durable, weather-resistant, corrosion-resistant, and waterproof.

The cable plug is a military-grade plug that has excellent anti-corrosion and erosion prevention performance. It can ensure the long-term use of the instrument. The plug also matches the relevant specifications to ensure the accuracy of the wind speed measurement.

The circuit PCB is made of military-grade A material that ensures the stability of the parameters and the quality of the electrical properties. The electronic components are all industrial chips that have extremely reliable electromagnetic interference resistance. They can ensure that the device can work normally in -20°C to 50°C, with 35% to 85% humidity (condensation).

This product can be widely used in engineering machinery (crane, crawler crane, gantry crane, tower crane, etc.), railways, ports, docks, power plants, meteorology, cableway, environment, greenhouse, breeding, air conditioning, energy monitoring, agriculture, health, clean room areas, and other fields that require wind speed measurement and corresponding signal output.

Please connect the external power (DC 12-24V) and the Arduino wiring to the same ground, i.e., connect GND to Arduino as well as to the external power.

Frequently Asked Questions

How do I wire the 4–20 mA output to a PLC?

Connect the positive terminal of your DC 12–24 V supply to the sensor’s V+ terminal, and the negative to V–. Run the loop wire from the sensor’s output terminal through your PLC’s analog input, using a 250 Ω termination resistor to convert current to voltage if required.

What wind speed range does this sensor cover?

This anemometer measures wind speeds from 0 m/s up to 30 m/s, with reliable detection starting at 0.4–0.8 m/s. The output current scales linearly across this range for accurate monitoring.

Is the sensor suitable for harsh outdoor environments?

Yes. The aluminum-alloy housing and cups are precision-cast for tight tolerances, providing corrosion resistance, waterproofing, and durability in industrial and marine settings.
