The detection ultrasonic transducer is to realize the generation and reception of ultrasonic signals
Main components With the development of non-destructive flaw detection technology,
The theoretical discussion and design and manufacture of energy devices have received extensive attention & projects
The pre-detection ultrasonic transducer is mainly made of piezoelectric material
Ceramic ultrasonic transducer, electrostatic transducer, electromagnetic acoustic transducer, etc.
In the field of non-destructive testing, people often call it an ultrasonic probe
It is a traditional longitudinal wave straight probe for piezoelectric ultrasonic testing
The probe is closely related to the method of ultrasonic detection
& Due to the wide range of application fields of ultrasonic testing, the method of ultrasonic testing
Many, so the types of ultrasound probes are also diverse & used for the main
The probes for dynamic ultrasonic testing include: broadband and narrow pulse
Head and narrow-band continuous wave probe, as well as shock wave probe, UHF probe
And ultra-low frequency probe; according to the working waveform, there are right-angle longitudinal wave probe and oblique
Angular shear wave probe, plate wave probe, surface wave and creeping wave probe; press coupling
There are direct contact probes and water immersion probes; according to the beam, there are different
Focusing flat probe and focusing probe; according to the working mode, there are single probe,
Double probe, mechanical scanning and electronic switching probe, electron beam scanning phase control
Array probes, etc.; according to the working environment, there are high temperature probes, miniature probes,
High-voltage probes, etc. & passive acoustic emission probes include multi-mode probes, wave
Shape identification and positioning probe, narrowband probe with small frequency window and large frequency
Narrowband probes with high rate window, etc. & Acoustic vibration detection method probes have acoustic resistance
Method probe, acoustic impact probe, Fokker probe, hardness probe, viscosity
Gauge probe, accelerometer probe, pressure sensor probe, etc. In addition,
There are some special probes for scientific research, such as miniature
Probes, broadband probes for impulse response testing, and sensitivity calibration
Standard probe etc.
