AI Technical Summary

Technical Problem

Existing ultrasonic transducers produce small amplitude sine waves for both transmission and reception, resulting in significant aftershock interference. When installed in an ultrasonic tube, the large drum area leads to high turbulence intensity, affecting waveform amplitude and measurement accuracy.

Method used

The modified steel-cased transducer includes a steel casing fixed on the outside, epoxy sealant filling the inside, a piezoelectric ceramic plate fixed at the bottom, red and white shielded wires, a polysulfone casing, and the piezoelectric ceramic plate being parallel to the casing. The steel casing wall thickness is 0.04-0.05mm, ensuring signal transmission stability and reliability.

Benefits of technology

It improves the amplitude of ultrasonic waveforms, reduces aftershock interference, enhances measurement accuracy, simplifies the potting process, expands the range of applications, and improves pairing consistency.
