【Abstract】 Magnetic stirrer is used widely in chemical titrating process to help solution mixing. Detecting rotation statue of the stirrer can improve the system reliability. This paper proposed one stirrer angular detection method based on hall magnetic field synchronous sensing. Stirrer movement mode can be determined. Base on the parameters of the movement,the stirrer can be controlled in high speed rotating reliably. The mixture efficiency can also be enhanced.The results of experiment show the feasibility and reliability of the method.更多还原
