acoustic CTA

The acoustic CTA is a full-featured hotwire anemometer bridge for dynamic flow velocity measurements in the range from 0 to 50m/s. Like the 4 channel counterpart 4CTA it is equipped with a standard signal output and a highpass-filtered output for headphones.

The signal out has an integrated lowpass filter at 5kHz to eliminate disturbing alias-effects from digital data aquisition. As an option the unfiltered signal may be used to enable dynamic measurements up to 20kHz.
