| Abstract: | The application of integration cell to the magnetic measurement of soft magnetic alloy are investigated. Integration drift parameter and integration time constant as main factors influencing the accuracy of measurements for integration cell are analyzed, The integrator was designed and developed, which can meet the requirent of the magnetic measurement for soft magnetic alloy. The integrator measuring accuracy is about 10^-9C. The application of 0.01 H standard transformer on measuring integrator system are also studied. The measurement test of saturation magnetization on the standard sample of soft magnetic alloy 1J85 was carried out, The system measuring accuracy is about 1.8%, which can reach the requirement of the magnetic measurement of soft magnetic alloy. |
