Peniel method for the automation of the ultrasonic monitoring based on the acoustic impedance

The industrial processes continuously require of better technologies which let to improve the effectiveness, efficiency and quality of their actions. One method to achieve this is based on the monitoring of the obtained sample or the industrial process itself. In this article is addressed the monitoring and the inspection of industrial products and processes through ultrasonic systems which analyze the behavior of the acoustic impedance. Some of the more important applications are in sectors such as energy, chemicals, aerospace, automobile, food, construction, among others. Although, the wide potential of this technique has been limited by the computational requirements of the algorithms associated with it, requiring of significant computing systems or devices, which is an obstacle for their implementation in small sensor systems. In this work is illustrated a novel signal processing method called Peniel, which has low computing requirements and has a significant circuital simplicity. This method was successfully implemented in a microcontroller of low computational capabilities.
