PROBLEM TO BE SOLVED: To provide a piezoelectric sensing device for measuring material thickness of targets such as pipes, tubes and other conduits that carry fluids.SOLUTION: A piezoelectric sensing device 100 comprises a substrate 102 and a piezoelectric element 104 with a ceramic body 106. The ceramic body 106 is configured with an electrode 108, a ground 110, and a wrap tab 112 constructed of gold plating or comparable conductive material that is deposited on the ceramic body 106. The substrate 102 comprises a flexible circuit material 114 provided with a first layer 116, a second layer 118, and a receiving area 120 that is configured to receive the piezoelectric element 104. |
