About Ultrasonic Transducers

Ultrasonic transducers send and receive waves for many types of sensing. Examples include distance, proximity, level, nondestructive evaluation, web break detection, counting, and security applications. They typically operate at their resonant frequency with various construction options, beam patterns, and power levels.

 Ultrasonic transducers have many critical specifications. Transmitting frequency is the usable frequency range of the device. Bandwidth is the difference between low and high operational frequency limits. Rated signal power available from transducer is another important specification. Transmit sensitivity is the ratio of sound pressure produced to input voltage. Receive sensitivity is the ratio of output voltage produced over sound pressure sensed. The beam angle is the total included angle of ultrasonic beam. In general, a high frequency transducer will produce a narrow beam and a lower frequency transducer a wider beam. The beam angle can be influenced somewhat by the transducer housing construction.
