🧼 Calibration & Maintenance
This sensor is factory-calibrated to produce a linear 4-20mA output corresponding to the wind speed range. No user calibration is typically required. For best performance, mount the sensor on a stable pole, free of obstructions. Regular maintenance includes visual inspections to ensure the cups are clean and spinning freely. The robust polycarbonate material and sealed bearings minimize the need for regular upkeep, making it suitable for remote installations.
⚠ Safety Information
Ensure the sensor is installed securely to prevent it from becoming a projectile in high winds. Always disconnect the power before performing any wiring or maintenance. The sensor is not designed to withstand direct lightning strikes, so a proper lightning protection system should be used for high-mast installations. Handle with care to avoid physical damage to the cups and internal components.
👍👎 Pros & Cons
| Pros | Cons |
|---|---|
| Industrial-grade reliability and robustness | Higher cost than hobbyist-grade anemometers |
| 4-20mA output is ideal for long-distance, noise-free transmission | Requires a current receiver or ADC with current-to-voltage converter |
| All-weather and corrosion-resistant construction | Does not measure wind direction |
| High-precision and wide measurement range | May be overkill for simple, non-critical applications |
