Application Cases

Ultrasonic non-destructive testing is a commonly used technique for detecting internal defects in materials and components. It leverages the propagation characteristics of ultrasonic waves in materials, detecting internal defects by receiving echo signals. Its application fields and scenarios are extremely broad. From material defect detection, structural health monitoring, pressure vessel inspection, to ultrasonic imaging, ultrasonic non-destructive testing technology plays a vital role. It can effectively assist researchers in understanding internal structural damage without compromising the integrity of the structure, whether it be materials or the human body.

The ATA-2000 series of high-voltage amplifiers are commonly used in ultrasonic non-destructive testing systems. Today, we will share a few relevant case studies with you, hoping to be of assistance to your research.

Case 1: Application of the ATA-2022B High-Voltage Amplifier in Piezoelectric Ultrasonic Guided Wave Non-Destructive Testing ExperimentsExperiment Overview: Four ATA-2022B high-voltage amplifiers were cascaded. A pulse signal generated by a signal generator was sent to the eight signal input ports of the four high-voltage amplifiers. After the amplifiers amplified the excitation signal without distortion, a signal with an amplitude of 200 Vpp and a frequency of 500 kHz was obtained and loaded onto the excitation probe. This signal was then applied to the piezoelectric array to excite guided waves of a specific mode. Meanwhile, an oscilloscope was used to observe the signals from the receiving probe, studying the propagation characteristics of guided waves in waveguides.

Case 2: Application of the ATA-2022B High-Voltage Amplifier in Stress Wave Method for Sleeve Grouting Density Detection Research

Experiment Overview: This experiment, based on the active detection technology of the stress wave method, conducted experimental research on different density conditions of steel bar sleeve grouting connections. Suitable characteristic parameters were selected, and a damage index was proposed to determine the density of the sleeve. The experimental results showed that the damage index could accurately characterize the density of the grouting and reflect grouting defects.

Case 3: Application of the ATA-2161 High-Voltage Amplifier in Non-Destructive Testing of LED Epilayers Based on Single-End Contact Principle

Experiment Overview: The experiment began with photoluminescence testing of the LED epilayer, obtaining the peak wavelength through a spectrometer. The LED epilayer to be tested was then placed on ITO glass, and the probe was slowly lowered until the LED epilayer emitted electroluminescence. The peak wavelength was obtained through the spectrometer, and the electrical parameters were captured by an oscilloscope. Finally, traditional electroluminescence (probe testing) was used to test the LED epilayer. Under the condition of consistent or similar relative intensity displayed by the spectrometer software, the electrical and optical parameters of the LED epilayer were obtained.

The ATA-2000 series is an ideal high-voltage amplifier capable of amplifying both AC and DC signals. With a maximum differential output of 1600 Vp-p (±800 Vp) high voltage, it can drive high-voltage loads. The voltage gain is digitally adjustable, and frequently used settings can be saved with a single button press, providing you with convenient and simple operational choices. Additionally, the dual-channel high-voltage amplifier outputs can be adjusted synchronously, and it can be used in conjunction with mainstream signal generators to achieve signal amplification.

ATA-2000 Series High-Voltage Amplifier Application Scenarios: Ultrasonic testing, non-destructive testing, driving piezoelectric ceramics, dielectrophoretic cell sorting, ultrasonic atomization, focused ultrasound.

As an extremely important testing technology, ultrasonic non-destructive testing has extensive applications in both industrial and medical fields. It provides precise defect detection and structural assessment, playing a crucial role in ensuring safe production and human health.
