Cảm biến đo hướng gió và tốc độ gió Campbell Scientific WINDSONIC4-L
The WindSonic4 is a two-dimensional ultrasonic anemometer for measuring wind direction and speed. It provides an alternative to traditional mechanical cup and vane or propeller and vane anemometers. This sonic wind sensor outputs an SDI-12 signal that can be read a a compatible Campbell Scientific data logger. (See the Compatibility section.)
The WindSonic4 is not recommended for conditions where rime, ice, or horizontal snow will occur. This sensor is not heated. Please contact Campbell Scientific for information on a heated 2-D sonic anemometer that will work in these conditions.
Note: The mounting equipment supplied with this sensor may vary depending on which Campbell Scientific regional office the sensor is ordered from.
Benefits and Features
- Low maintenance—no moving parts significantly reduces maintenance cost and time
- Provides a minimum detectable wind speed of 0.01 meters per second
- Compatible with most Campbell Scientific data loggers
The WindSonic4 uses two pairs of orthogonally oriented transducers to sense the horizontal wind. The transducers bounce the ultrasonic signal from a hood, thus minimizing the effects of transducer shadowing and flow distortion.
Unlike mechanical anemometers, the WindSonic4 has no moving parts to be periodically replaced—minimizing routine maintenance costs.
