The Influence of Temperature on Piezoelectric Effect of Ultrasonic Probe

By heating the reference block on a constant temperature worktable, and testing the changes of the probes capability of transmitting and receiving ultrasonic wave, this paper investigated that how the temperature influences probes piezoelectric effect of the probe. The experimental results showed that high temperature weakened the piezoelectric effect, made the probes capability of transmitting and receiving ultrasonic decreased even lost. So that the high temperature restricted the application of high temperature UT.
