    Abstract: Disclosed is an NDT/NDI probe array and manufacturing method. The probe array includes a sheet of flexible circuit 10 with a plurality of lower pins 102 and corresponding, electrically connected, upper pins 104. The probe further comprises a backing block 12, a layer of piezoelectric ceramic 16 having a plurality of conductive elements 162, a matching layer 18 and a frame 14. An adhesive material such as epoxy is applied to the circuit, the backing, the ceramic and the matching layer, and all are aligned and stack pressed at least partially into the frame and permanently bonded in such a fashion that each of the lower pins of the flexible circuit is firmly and permanently in contact with a corresponding one of the conductive elements of the ceramic.

    Abstract: In a process plant, a first series of impedance measurements from a valve body are received. The first series of impedance measurements are stored. A second series of impedance measurements from the valve body are received. The second series of impedance measurements from the valve body are stored. The first series and second series of impedance measurements are compared. An indication of loss of integrity of the valve body is generated if the first series of impedance measurements deviates from the second series of impedance measurements.

    Abstract: An EMAT that generates horizontally polarized shear ultrasonic waves is combined with a PZT that generates longitudinal ultrasonic waves to provide simultaneous or sequential inspection of a test component material for improved accuracy in estimating properties of the material or detecting and estimating the dimensions of defects in the material. The transducer combination is constructed so that the EMAT and PZT elements are concentric and therefore interrogate approximately the same volume of the test component material. Nonferromagnetic insulators, such as elastomers, are installed on the bottom surface of PZT component to increase the transmission and reception the ultrasonic waves into the test component. Ferromagnetic, acoustic-absorbing materials are installed on the top surface of the EMAT coil component to minimize generation of ultrasonic waves in the bias magnet.
