Abstract
An ultrasonic transducer for a measuring instrument includes a housing container with a support plate and a piezoelectric element that is supported by the support plate and has a substantially circular shape. The piezoelectric element includes multiple substantially sector-shaped oscillation parts that are divided by multiple grooves that communicate with each other at the central part and extend radially. The piezoelectric element oscillates in the thickness direction Ain the first frequency band and in the radial direction Ain the second frequency band, which is lower than the first frequency band. The ultrasonic transducer is capable of expanding the frequency band suitable for transmitting and receiving ultrasound.
