  • DEVICE AND SYSTEM FOR MEASURING MATERIAL THICKNESS
    Publication number: 20120294124
    Abstract: A piezoelectric sensing device is described for measuring material thickness of target such as pipes, tubes, and other conduits that carry fluids. The piezoelectric sensing device comprises a substrate such as a flexible circuit material, a piezoceramic element, and a solder layer disposed therebetween. These features are arranged in manner that provides a low-profile measurement device suitable for high-temperature applications such as those applications in which the temperature exceeds 120° C. Embodiments of the piezoelectric sensing device can be configured for use as stand-alone units separately located on the target or for use as a string of sensing elements coupled together by way of the flexible circuit material.
    Type: Application
