The Smart CTA is a professional but easy-to-use hot-wire anemometer. In a compact design, two CTA units are integrated which enable not only a one-dimensional probe, but also a two-dimensional probe, to use with just one main unit. The Smart CTA offers the frequency response up to 20 kHz, so for most applications it can be employed.
A hot-wire anemometer (HWA) is an instrument that measures turbulence intensity of airflow and for its frequency analyses. A HWA detects velocities from analog electrical signals continuously outputted from the CTA feedback circuit. The hot-wire sensors are very tiny, a diameter of about a few microns, and therefore bring high thermal responsiveness. Those small sensors enable to capture information of the microstructure of the flow. By traversing the probe, velocity distribution can be also measured.
