The TriSonicaTM

Applied Technologies Inc.'s latest Ultrasonic Anemometer - TriSonica
The TriSonicaTM

The TriSonicaTM Solid-State Wind System, manufactured by AnemomentTM .  Even though it was designed for horizontal air flow, it can also provide measurements of all three dimensions of air flow. The open path provides the least possible air flow distortion of the wind field.

Four measurement paths provide a redundant measurement. The path with the most distortion is removed from the calculations to provide accurate wind measurements.

Data emulation allows for the direct connection to existing data loggers and systems without costly changes to associated electronics. Data output is factory set to user requirements and includes the emulation of many common types of wind sensors.

Optional heating extends the lower operating temperature of the sensor and permits continuous operation during heavy ice and snow.

Additional Options:

Digital Outputs – Other digital outputs available are RS-422, RS-485, and SDI-12.

Output Options – Data available for the digital output only: Two axes orthogonal format
(U, V) for Wind Speed & Wind Direction. Higher absolute accuracy for ultrasonic temperature. 

Custom Formats – Custom output formats are available for large quantity orders.

Color – The standard color is black, but other colors are available upon request.         

Mounting – The base can be adapted to provide a mount to a variety of structures.
Check with the factory for available options.

Interface Box – An external box which can be connected in series with the sonic cable to
provide a place for battery power along with a wide variety of input/output interface options.  

Heater – A heater can be provided to protect against icing conditions.

Battery System– To provide the longest possible battery operation, given a full charge in the
smallest package profile, the Li-Po (Lithium Polymer) battery is used, with its own special charger.

Backup Battery – When a backup battery is required, it is expected that the unit will be
operated on an external power source. This battery will be a Gel-Cell type.
