FU Yong-le1, JIN Hong1. Design and implementation of axis of rotation speed measurement system based on capacitive sensor[J]. 2011, 30(6): 87-89+92. DOI: 10.13873/j.1000-97872011.06.030.
Axis of rotation speed measurement is commonly used in automotive power systems and engine control systems.A new type of capacitive sensors used to measure the speed of rotation axis test system is introduced.The system has simple structure
high precision
particular suitable for small spaces shaft speed measurement.Through the study of capacitive sensors
a speed measurement is achieved
the system maximum error of the reference is 0.18 %
