  • Receiver for a pulsed eddy current system
    Patent number: 12704479
    Abstract: A receiver for a Pulsed Eddy Current (PEC) system configured to detect a changing electromagnetic field generated by eddy currents induced in an object of an electrically conductive material. The receiver includes an electrically conductive receiver coil, a high-voltage receiver channel, a low-voltage receiver channel, and an over-voltage protection connected between the receiver coil and the LVRC. The OVP includes a bias circuit B, a diode D connected between the receiver coil and the bias circuit, and a capacitor C connected between the bias circuit and the LVRC.
    Type: Grant
