发明名称 AIR FLOW RATE DETECTING DEVICE
摘要 <p>PURPOSE:To reduce the weight of an air flow rate detecting device having two kinds of outputs, air flow rate signals and air temperature signals, by reducing the number of wire harness connecting the detecting device to an opposite-side device. CONSTITUTION:After converting an air flow rate signal into a switching signal and air temperature signal into a voltage mixer circuit 4 transmits a combined signal of both the signals. For example, a filter having the same time constant as the circuit 4 has can be provided on the opposite side for inputting the signal and voltage and separates the air flow rate and temperature signals from each other. Therefore, an air flow rate detecting device which can be reduced in the number of wire harness for transmitting signals and weight can be obtained and, at the same time, a system having excellent signal reproducibility and high noise margin can be realized.</p>
