sonic anemometer

FEATURES
• No Moving Parts
• No Periodic Maintenance
• Digital and Analog Outputs
• Automatic North Alignment (Optional)
• Ice-Free Operation (Optional)

Climatronics' sonic anemometer (P/N 102263), the Sonimometer , is designed for ambient wind sensing and as a direct replacement for conventional mechanical anemometers, both in terms of performance and cost. It requires no periodic maintenance or calibration.

The Sonimometer operates on the principle of the measurement of the speed of sound in air. All electronics utilize the latest solid state surface mount technology conserving power, size, and weight. Power consumption is low, at less than 0.5W for the unheated version.

The Sonimometer body is slender and aerodynamic to assure that minimum turbulence is introduced into the measured air stream. The Sonimometer head measures 4 inches in diameter and 8 inches high. This makes the Sonimometer unobtrusive and therefore ideal for applications where detection wants to be minimized, or where vandalism may be anticipated.

The electronics produce both digital and analog outputs, which are compatible with any of Climatronics' and other commonly available data acquisition systems. A flux -gate compass is available where self-orientation is important. Wind direction is automatically processed and output referenced to magnetic north.

The sensor is ideal for applications requiring high reliability, low maintenance, ice-free operation, ruggedness or portability. Its small size and surface area allow the Sonimometer to be kept ice free even at relatively low power levels. The heated version of the Sonimometer , P/N 102622, includes a metal sensor housing and the heating elements. These are factory-installed. The heater control box, P/N 102626, is ordered separately.

The unheated Sonimometer mounts on the "QuickMount", P/N 102621. The heated Sonimometer attaches to mount P/N 102286.
