Overview

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. 

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.

Key Advantages

No Moving Parts
Minimizes routine maintenance costs

Technical Description

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.

Benefits

  • 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

Compatibility

Mounting

The WindSonic4 is shipped with the 17387 mounting kit. This mounting kit is used to attach the sensor to a CM202, CM204, or CM206 crossarm. The crossarm is then mounted to a tripod or tower.

Data Logger Considerations

The WindSonic4 is connected to one control port, +12 Vdc, and ground. Up to ten WindSonic4s (each with a unique address) can be connected to one data logger control port.

Programming

The SDI12 instruction is used to collect data from the WindSonic4.
