Embodiment Construction
[0036] The present invention is described below in conjunction with accompanying drawing, but they do not limit the present invention in any way.
[0037] Such as figure 1 Shown is a magnetostrictive transducer automatic impedance matching device, the composition of the automatic impedance matching device includes an impedance matching module, a signal acquisition module, a feedback module and a single-chip microcomputer control module;
[0038] Its connection relationship is: one end of the impedance matching module is connected to the output end of the power supply, and the other end is connected to one end of the magnetostrictive transducer; one end of the signal acquisition module is connected to the output end of the power supply, and the other end of the signal acquisition module is connected to the magnetostrictive transducer. The other end of the telescopic transducer, while the output end of the signal acquisition module is connected to one end of the feedback module;...
