R. The difference between M.YOUNG mechanical anemometer 05103 and 05305
Date: 2025-06-20Read: 9
R. M. YOUNG's 05103 and 05305 are both very reliable and commonly used mechanical wind speed sensors, but their design and application focus are different. The main difference lies inStart wind speed, response characteristics, and typical application scenarios：
1. Wind cup/propeller design
| parameter | 05103 | 05305 |
|---|---|---|
| sensor type | Propeller anemometer(Horizontal axis) | Propeller anemometer(Horizontal axis) |
| Leaf material | Polypropylene (PP) | Carbon fiber reinforced thermoplastic |
| diameter | 18 cm | 20 cm(Larger) |
| starting wind speed | 1.0 m/s(High threshold) | 0.4 m/s(More sensitive to weak winds) |
| Distance constant | 2.7 m (slow response) | 2.1 m(Faster response) |
| Output signal per revolution | 3 sine wave cycles (0.098 m/Hz) | 3 sine wave cycles（0.102 m/Hz） |
interpretation：
05305The propeller design significantly reduces the starting wind speed (0.4 m/s), making it more suitable for monitoring light wind environments (such as air quality monitoring).
05103ofPropeller designMore versatile, but with slower response speed (distance constant 2.7m).
2. Wind vane characteristics
| parameter | 05103 | 05305 |
|---|---|---|
| Turning radius | 38 cm (15 inches) | 48.3 cm (19 inches) |
| damping ratio | 0.3 | 0.45(Stronger damping) |
| Threshold sensitivity(10 ° angle of inclination) | 1.1 m/s | 0.5 m/s |
| Delay distance(50% recovery) | 1.3 m | 1.2 m |
05103 (Propeller type)：
Universal wind speed measurement.
Meteorological station (regular meteorological observation).
Environmental monitoring.
Industrial and scientific applications with less stringent wind speed requirements.
Scenarios that do not require extremely low starting wind speeds or maximum gust response speeds.
05305 (propeller type):
Requires extremely low start-up wind speedApplications such as studying breezes, indoor ventilation, greenhouses, and precision environmental control.
Need for higher gust responseApplications such as turbulence research, wind engineering, air quality diffusion models, and scenarios that require capturing rapid wind changes.
Frequently associated with wind indicatorsIntegrated togetherAs aWind speed and direction combination sensor(Because the propeller itself must be aimed at the wind direction).
Applications with stricter requirements for sensor size and weight (propeller type is more compact and lightweight).
