| Abstract: | The paper discusses system design for measuring multi-channel and wide magnetic field range utilizing HMC1023 magnetorisistor sensors.The paper makes the multi-channel and realtime sampling be reality by employing instrument amplifier and sampling holder.PGA is used for adjusting amplifying time in the system,so the system can measure wide magnetic field.The paper discusses the realtime display of sensors output in PC,too. |
