Which circuit generates a burst of energy to send to the transducer in ultrasonic testing?

The pulser is the component responsible for generating a burst of electrical energy that is sent to the transducer in ultrasonic testing. This energy is converted by the transducer into mechanical vibrations, which then propagate as ultrasonic waves through the test material. The burst of energy created by the pulser is crucial as it initiates the ultrasonic inspection process.

In contrast, the receiver circuit processes the signals that are reflected back from the material being tested. The amplifier’s role is to amplify these received signals for better analysis. The oscillator, while important in generating signals in other contexts, does not specifically perform the function of creating the pulse needed for ultrasonic testing. Thus, the pulser is essential in creating the initial energy burst crucial for conducting ultrasonic testing effectively.
