A sensor for ultrasonically measuring a portion of a structure, the sensor comprising: (a) a transducer for converting an analog transmit signal to an ultrasonic transmit signal, and for converting an ultrasonic reflected signal to an analog reflected signal; (b) a housing connected to the transducer; (c) a connection mechanism for permanently installing the transductor on the structure; (d) electrical components contained within the housing, the electrical components comprising at least: a processor having an integrated A/D converter and configured for Equivalent-Time Sampling (ETS) analog reflected signals from the transducer to obtain a digitized composite signal, processing the digitized composite reflected signal to generate an A-scan signal; and transmitting the data signal based on the A-scan signal, wherein the electrical components do not comprise a discrete A/D converter or a field programmable gate array (FPGA). |
