Introdução
A 3 cup anemometer, also known as a three-cup wind speed sensor or cup anemometer, is a widely used instrument for accurate wind speed measurement. Featuring a three-cup rotor design, it delivers stable performance, fast response, and a low starting threshold of ≤0.3 m/s, making it suitable for continuous outdoor monitoring. As a reliable three cup anemometer for estações meteorológicas, wind energy, agriculture, and environmental monitoring, it supports multiple output options and OEM customization for different project requirements.
Structure 3 Cup Anemometer
- Wind cups: 3 hemispheres / lightweight conical cups (carbon fiber, aluminum alloy), arranged concavely in the same direction; rotational torque is generated by the difference in wind resistance between the concave and convex surfaces.
- Cup mount (trident bracket): Three arms spaced 120° apart secure the three wind cups; rigidly connected to the main shaft, they rotate in unison.
- Rotating Shaft: Transmits the rotational motion of the wind cup to the internal sensing mechanism, featuring excellent concentricity and wear resistance.
- Elemento sensor: Uses Hall effect sensors, magnetoelectric sensors, or optical encoders to detect rotational speed and convert it into a corresponding electrical signal.
- Precision Bearings: Equipped with built-in high-precision, low-friction bearings to reduce the start-up wind speed and improve measurement sensitivity and long-term operational stability.
- Circuito de processamento de sinais: Processes the acquired rotational speed signals and outputs standard signals such as pulses, RS485, 4–20 mA, 0–5 V, and 0–10 V.
- Caixa de proteção: Manufactured from aluminum alloy, stainless steel, or high-strength engineering plastics, it offers excellent corrosion resistance, UV resistance, and waterproofing.
- Mounting Base: Used for secure installation on weather poles, brackets, or monitoring equipment, facilitating on-site deployment and maintenance.
Working Principle of 3 cup anemometer
- Wind cup sensor assembly: Three cups are mounted at 120° intervals with their concave surfaces facing the same direction; rotational torque is generated by the pressure difference between the convex and concave wind cups.
- Constant-speed rotation mechanism: Once the wind speed stabilizes, the forces acting on the wind cups are balanced, and the rotational speed corresponds to the real-time wind speed.
- Pulse Generation Assembly: The shaft drives the light-blocking disc and magnetic rod to rotate in sync, outputting a pulse signal proportional to the rotational speed.
- Signal Conversion Module: The circuit counts the number of pulses and calculates the actual wind speed value through conversion.
- Inherent Error Characteristics: Due to the rotational inertia of the cups, wind speed measurements tend to be higher under gusty conditions, resulting in an over-efficiency effect of approximately 10%.
