Development of Magnetoelectric Speed Sensor for Engine with High Environment Adaptability

Abstract

Abstract The high reliable environment adaptive magnetoelectric speed sensor developed by this project is mainly used in the field of engine measurement and control. This project can effectively improve the accuracy and reliability of sensor measurement by adopting a new output design of redundancy synchronous coil and transformer secondary amplification design. By optimizing the induction coil, magnetic steel and internal structure, the sensor has outstanding performance such as low speed work, high sensitivity and low noise; At the same time, the project also through the overall structure of the sensor, material design, packaging technology and other optimization design, to ensure that the sensor meets the wide temperature zone, vibration resistance, impact resistance and full seal protection and a series of high reliable environmental adaptability technical requirements.
