AMB Magnetic Field Homogeneity Test System Design

This article designs a kind of new magnetism aerosol bearing uniform reflectoscope reflector which is controlled by the microprocessor,uses the Hall sensor to obtain the magnetic induction intensity the signal,uses AD574 to complete the signal gathering,the microprocessor uses the STC89C51X series,carries on to the survey result,uses the independent module to carry on the demonstration and the memory.Because the Hall sensor and the amplifier are the linear element,overall system linear is higher,the measuring Error may in survey maximum value 2%.
