1. Product Overview
The EC-9SA Wind Speed Sensor is a high-reliability, high-performance instrument designed for accurate wind speed measurement in demanding environments. It outputs an electrical signal that is linearly correlated with ambient wind speed and integrates robust protection circuits against radio-frequency interference, electromagnetic interference, and lightning surges.
Constructed from high-precision alloy materials with a protective coating, the sensor offers excellent waterproof and corrosion resistance. All internal and rotating components are fully sealed, effectively preventing water, salt spray, and dust intrusion. This makes the EC-9SA ideal for long-term outdoor deployment in harsh conditions.
The sensor is widely used in high-altitude operations, engineering machinery, ports, meteorological stations, environmental monitoring, wind energy systems, and other industrial applications where reliable wind speed data is critical.
2. Measurement Principle
The EC-9SA Wind Speed Sensor adopts a non-contact magnetic sensing principle to ensure high accuracy, long service life, and stable performance. The rotational motion of the wind cup is detected by the internal sensor module, which converts wind speed into a corresponding electrical output signal for real-time data acquisition and processing.
3. Key Features
High Accuracy & Reliability – Advanced non-contact magnetic sensing for precise measurement.
Wide Measurement Range – Capable of detecting wind speeds from 0 to 70 m/s.
Low Startup Speed – ≤ 0.5 m/s, enabling detection of light wind conditions.
Strong Anti-Interference Protection – Built-in EMC protection against electromagnetic noise and lightning surges.
Rugged & Durable Design – High-precision alloy body with corrosion-resistant coating.
Fully Sealed Structure (IP65) – Prevents water, salt spray, and dust ingress.
Multiple Output Options – Supports RS485, 4–20 mA, 0–5V, or pulse frequency output.
Easy Installation & Maintenance – Compact, lightweight, and reliable structure.
