摘要

Using the hole sensor, being method and the device in order to measure the substance of the magnetic field, the particular hole sensor had, terminal opposite in order to supply the excited signal (A1, A2, B1 and B2) and terminal opposite in order to grasp the detection signal (A1, A2, B1 and B2) one which it possesses hole plate (101, 102, 103 and 104) at least, as for the electric current which indicates the substance where voltage was supplied by the hole plate the source of the impedance which can be ignored (105) from as an excited signal, was measured, the pickup of the impedance which can be ignored (108 and 1098,110) it is removed from the hole plate with, as a detection signal.
