Ultrasonic Transducers Information Ultrasonic transducers send and receive waves for many types of sensing. They convert energy into high frequency sound waves in the ultrasonic range.  These sound waves are then focused on a target and the echo is read by sensors to determine a specific variable such as distance, proximity, speed, or level in applications like nondestructive evaluation, web break detection, counting, security applications, and cutting and welding.
