ULTRASONIC NONDESTRUCTIVE TESTING – SOLUTIONS 超声无损检测—解决方案 Ultrasonic Nondestructive Testing Solutions In industrial nondestructive testing (NDT), physical energies such as sound waves and electromagnetic fields serve as common information carriers, playing a critical role in product quality control and new-material research. However, as these energies propagate through materials, they suffer attenuation or distortion from absorption, scattering, and other mechanisms, which drastically reduces NDT’s sensitivity and resolution when detecting deeply buried flaws or minute damage. This also limits its effectiveness and reliability in complex scenarios such as composite-material inspection. Consequently, NDT requires excitation signals of sufficient intensity to secure adequate initial energy, penetration depth, and signal-to-noise ratio, thereby ensuring accurate results. Recommended Products SERIES Maximum Output Voltage Maximum Output Current Maximum Output Power Solution Advantages By merging high-voltage excitation with intelligent signal processing, it pinpoints minute anomalies in deep-seated defects. Four-quadrant operation supports capacitive, inductive, and resistive loads. Multiple frequency, voltage, and current ranges are selectable. Harmonic distortion is suppressed to 0.1%. Fully programmable and remotely controllable for seamless integration with any test platform. Wideband amplification ensures high-fidelity signal boost at the NDT transmitter. Full protection: over-current, over-voltage, and over-temperature shutdown.

ULTRASONIC NONDESTRUCTIVE TESTING – SOLUTIONS Case 1: Ultrasonic Guided-Wave Experiment for Electrode-Depth Measurement in Submerged-Arc Furnaces A submerged-arc furnace (SAF) is a large-scale electrometallurgical unit for ore smelting. Because the electrodes are buried deep in ultra-high-temperature charge, on-line monitoring is extremely difficult. To solve this problem, researchers have introduced an acoustic technique that uses ultrasonic guided waves to detect Electrode Insertion Depth (EID). In this field, Aigtek’s ATA-2000 series power amplifiers are widely adopted; instruments of different...
