Abstract

This paper regards the experimental characterisation of the dynamical response of a home-made low cost constant-temperature hot-wire anemometer (CTA), developed for industrial and research applications. In order to evaluate the circuit dynamics, both a square-wave and a sine-wave have been imposed to the reference offset voltage of the anemometer for different operating conditions. A linear approximation of the CTA behavior was carried out by adjusting the transfer functions forms and constants. Results have shown that, depending on the particular conditions, a second or third order model should be used
