INTRODUCTION OF TRANSDUCERS. A transducer is a device that convert one form of energy to other form. It converts the measurand to a usable electrical signal.. How it Works. The sensor emits short bursts of sound, and listens for the echo off nearby objects. By measuring the time of flight, distance can be computed. When. it doesn’t work. When waves are not reflected back towards the sensor. Hussain Altammar. Mechanical Engineering Department, University of Wisconsin-Milwaukee. Objective. The objective of this study is to investigate the feasibility of using shear mode piezoelectric (PZT) transducers in structural health monitoring for evaluation of adhesive joints.. M. obile .
