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 %.
