Thies First Class Advanced Anemometer

The Thies First Class Advanced (FCA) Anemometer is a class 1 anemometer that delivers high-end performance in any terrain.

Product Configurations

Thies First Class Advanced Anemometer | MEASNET Calibrated



Details

The Thies FCA Anemometer is ideally suited for wind resource assessment and power performance studies at IEC 61400-12-1 Class A and B sites.

The Thies FCA Anemometer comes with a MEASNET calibration certificate, and it is compatible with all Symphonie series data loggers. You will need to use Signal Conditioning Modules (SCM #3151) when connecting more than six anemometers to a SymphoniePLUS®3 Data Logger, but no interface module is required when connecting to a SymphoniePRO® Data Logger. These sensors can also be integrated seamlessly with our NOW Systems.

Use the Thies Adapter boom extension (#9344) to mount Thies First Class Advanced Anemometers on any 25 mm (.98”) diameter vertical pipe, such as RNRG boom #4478 or any boom already fitted with a WindSensor Adapter Kit.
