PUI Audio UTR Ultrasonic Transducers are available in a small surface-mount package for a 40KHz sensor and two high-frequency sensors at 225KHz and 295KHz in a lead wire connector configuration. These high-frequency sensors have an acoustic material that enhances the transmission ability of ultrasonic signals in gas media and for short-range precision detection. These ultrasonic transducers act as transmitter and receiver, providing accurate and reliable measurements in a variety of environments. The transducers' resonator has a funnel shape to transmit ultrasonic waves. These waves are generated by efficiently vibrating the resonator to the air or to concentrate ultrasonic waves from the air on the center of resonance. PUI Audio UTR Ultrasonic Transducers can be used for object detection, obstacle avoidance, level measurement, flow measurement, robotics, and automation control.
