摘　　要：节气门用角度传感器研究逐渐趋于小型化、智能化以及非接触测量。用一种线性霍尔元件MLX90316设计制作了节气门传感器,论述了该传感器的原理与组成结构,研究了它的独立线性度、重复性和一致性。实验结果表明:本传感器使用水平磁通量为50 mT的圆盘形磁铁,磁铁与芯片的距离为5 mm,在磁铁转速为150 r/s时,传感器的独立线性度小于1.1%,同一传感器的重复性为2%,同批次传感器的一致性约为2%。Throttle angular sensor are tend to be miniaturized, intellectualized and non-contact measurement. Design and fabricate throttle sensor using a set of linear Hall compnent MLX90316 ,and principle and structure of the sensor are described,its independent linearity, repeatability and consistency are researched. The result shows that the sensor uses disk-shaped magnet with horizontal flux of 50 mT, distance between magnet and chip is 5 mm, while rotating speed of magnet is 150 r/s, independent linearity of sensor is less than 1.1% , the repeatability is 2 % and the conformity of the same batch is about 2 %.
