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 %.
