Energy performance of NTC-based constant temperature anemometers

This work presents an analysis performance for a Wheatstone-Bridge Constant Temperature Anemometer architecture (WB-CTA) using a NTC sensor and taking into account its energy consumption, sensitivity and settling time. The best design parameters are investigated considering the trade-off between these performance requirements. The study is conducted using dynamic behavior and circuit-level models of the thermo-resistive sensor and Wheatstone bridge. Simulations results are presented and discussed.
