Abstract :
The electronic design of a system for measurement the ultrasonic flight time in no dispersive solid samples; using pulse-echo overlap method, is presented. The system is based on a microprocessor 87C51; which allows to reduce the quantity of electronic components, as well as to achieve a simpler and more reliable design. The results obtained are presented during part of the validation process of the system.
