A thermal anemometer, including a constant temperature anemometer bridge excitation circuit together with multiple signal comparators and a tapped resistance reference divider, providing a linearized digital output signal, together with a digitally controlled output section that presents a simultaneous linear analog output signal. All logic switching is actuated by the anemometer signal itself. Both unipolar (non-directional) and bipolar (directional) constant temperature anemometer signals are linearized, digitized, and processed with a minimum number of steps and component parts to provide simultaneous digital and analog output signals. Generic transducer electrical output signal digitizing is disclosed. |
