Abstract: An ultrasonic sensor assembly for testing a pipe includes a first and second transducer rings attached to the pipe and spaced apart along a length of the pipe. The first transducer ring includes a plurality of transmitters for transmitting a wave, such as a non-dispersive guided wave. The first transducer ring transmits the wave along the pipe. The second transducer ring includes a plurality of receivers for receiving the wave. A relative position of the first transducer ring with respect to a circumferential position of the second transducer ring is determined based on characteristics of the wave received by the second transducer ring. A method of positioning the ultrasonic sensor assembly on the pipe is also provided.

Abstract: Systems and methods are disclosed herein in which multi-level square wave excitation signals are used instead of or in addition to fully-analog excitation signals to drive an array of transceiver elements to create a sound field. Use of multi-level square wave excitation signals produces acceptable transceiver output with reduced complexity, cost, and/or power consumption as compared with use of fully-analog excitation signals. In addition, use of such signals facilitates system implementation using application-specific integrated circuits (ASICs) and is not as restricted in voltage level and speed. At the same time, the benefits and applications of fully-analog excitation signals (e.g., acoustic holography, beam superposition, signal-to-noise ratio (SNR) improvements, suppression of parasitic modes, increased material penetration, potential for coded pulsing algorithms and suppression of side lobes in ultrasonic field) can still be achieved with multi-level square wave excitation signals.
Abstract translation: 本文公开了系统和方法，其中使用多电平方波激励信号来代替或除了全模拟激励信号以驱动收发器元件阵列以产生声场。 与使用全模拟激励信号相比，多级方波激励信号的使用产生可接收的收发器输出，降低了复杂性，成本和/或功耗。 此外，这种信号的使用有利于使用专用集成电路（ASIC）的系统实现，并且在电压电平和速度方面不受限制。 同时，全模拟激励信号的优点和应用（例如声全息，光束叠加，信噪比（SNR）改善，寄生模式抑制，材料渗透增加，编码脉冲算法的潜力和 在超声场中抑制旁瓣）仍然可以通过多级方波激励信号来实现。

Abstract: An ultrasonic sensor assembly detects a characteristic of a pipe. The ultrasonic sensor assembly includes first and second transducer rings spaced apart along a length of the pipe. Each of the first and second transducer rings can transmit a first wave longitudinally along the pipe and receive a reflection of the transmitted first wave from the characteristic. The first transducer ring can use results related to the reflection of the transmitted first wave to guide a second wave along the pipe that is received by the second transducer ring. Methods of detecting a characteristic of the pipe are also provided.
