Abstract:
This paper describes a low-cost servo acceleration sensor suitable for automotive applications such as the antilock braking system or the traction control system. The sensor comprises a weight, a pair of flat springs, a magnetic circuit, an optical system and an electric circuit. The weight consists of a torquer coil and a pair of damper plates.In order to reduce the cost, we developed a unique construction suitable for mass production.The results of the performance tests show an excellent linearity and fine temperature characteristics over the operating temperature range of -40 to +85° C.
