| Abstract: | A new magnetic sensor,which has simple structure and high reliability,is developed by analyzing the change of leakage magnetic field while the solinoid valve is working to meet the requirements of non-contact measurement for the solenoid valve response characteristics of a rocket or missile.The influence of side magnetic field can be minimized and the reliability of the leakage magnetic field detection for the solinoid valve can be improved by adopting rational anti-jamming method.The measurement of the solenoid valve＇s on-off characteristics are performed with this new magnetic sensor.The results show that the new magnetic sensor can meet the application requirements of non-contact measurement for the solenoid valve＇s response characteristics. |
