Summary:A non-contact eddy-current detecting device includes a first node of a first coil connecting with the second node of a first power amplifier and the first node of a second amplifier. The first node of the second coil connects with the second node of the second power amplifier and the first node of the of the first power amplifier. The first node and second node of the negative feedback device connect with the first node of the first power amplifier and the first node of the second power amplifier respectively. The third node of the negative feedback connects with the third node of the first power amplifier and the third node of the second power amplifier. The first node of the current detecting device connects with the second node of the first power amplifier and the second node of the second power amplifier. The second node of the current detecting device outputs a detecting signal.
