Beschreibung
Zusammenfassung:	A temperature-dependent resistor is placed in path of air intake. Resistor forms part of a bridge circuit. Amplifier input connected to the diagonal of bridge circuit, amplifier output connected in parallel with the two branches of bridge. Resulting feedback circuit maintains temperature-dependent resistor at a constant temperature by changing current therethrough to compensate for different cooling effects of air stream. Output voltage of amplifier constitutes measure of regulator current through temperature-dependent resistor and therefore measure of air intake. Circuits using amplifier output voltage to control fuel injection also illustrated.
