摘要
质量空气流量传感器广泛应用于发动机测试及控制系统。介绍了热线和热膜式质量空气流量传感器的原理、电路特点、传感器输出电压与空气流量的关系、环境空气温度对测量结果的影响；阐述了环境空气温度补偿电阻减小测量误差的原理。
Air mass flow sensor is broadly used in engine testing and control system. Principle of hot wire and hot film type air mass flow sensor,feature of electronical circuit,relation between output voltage of sensor and the air flow and effect of ambient air temperature to result of measurement are presented. Also principle of test error reducing by ambient air temperature compensating electrical resistance is expounded.
