I. Product Applications
The array ultrasonic imaging inspection system is a high-end nondestructive testing device that employs advanced ultrasonic pulse‑echo technology. It enables structural imaging, object detection, and defect identification, ensuring highly accurate and reliable results. This instrument is suitable for a wide range of complex inspection environments and is primarily used for:
- Single-sided structural inspection: for components that cannot be accessed from both sides, such as tunnel linings, bridge web plates, walls, and pile foundations.
- Internal defect detection: voids, honeycombing, porosity, delamination, cracks, debonding, and internal damage.
- Precise Thickness Measurement: Inspection of Concrete, Lining, Pavement, and Slope Protection Layer Thicknesses
- Reinforcement and Pipeline Localization: Imaging for Multi-Layer Reinforcement, Prestressed Ducts, and Embedded Pipeline Localization
- Grouting Fullness Inspection: Assessment of Grouting Integrity in Sleeves, Corrugated Ducts, and Prestressed Conduits
- Large‑scale thick‑section inspection: dams, nuclear power plants, wind‑farm foundations, port terminals, and subway structures.
II. Product Features
- Deep Penetration, High Sensitivity: Maximum detection depth of 2000 mm in plain concrete; 800–1200 mm in reinforced concrete.
- Adaptive Design: Independent spring suspension structure, designed to adapt to multiple testing scenarios and eliminate the need for coupling agents.
- Convenient operation: compact and lightweight, easy to use, quick to learn, and supports single-sided inspection.
- High‑efficiency detection: Rapid response, with a single-point measurement taking only 1 second.
- High resolution: Utilizing shear-wave‑dominated inspection technology, even minute defects are clearly visible.
- 3D Imaging: Upon completion of the inspection, an intuitive three-dimensional image can be generated, clearly revealing the internal structure.

VI. Equipment Description
The array ultrasonic imaging system supports cascaded stitching of multiple units, enabling efficient inspection over a larger sampling area.
- Flexible expansion of the detection range: A single device is suitable for small‑area inspections, while cascading multiple units enables coverage of large components or long‑span structures, achieving comprehensive scanning from localized to holistic assessments.
- Data Synchronization and Continuity: Multiple devices operate in concert, with acquired data automatically synchronized to ensure signal integrity and imaging accuracy, yielding continuous, seamless inspection data.
- Efficient and Reliable: By employing cascaded splicing, it not only expands the inspection coverage but also ensures simple operation and rapid data acquisition, enabling efficient and reliable internal inspections of large components and complex structures.
- Wide-ranging applications: Suitable for long‑span bridge inspections, full‑section tunnel scanning, and internal imaging of dams and large hydraulic structures, enabling users to effortlessly handle a variety of demanding inspection tasks.
- 7-inch touch-screen display, easier to operate than button-based controls.
- The device can transmit data to a computer, where it is processed and annotated using the accompanying software.
- The device features a built-in high-capacity rechargeable battery that provides up to 8 hours of continuous operation and supports quick battery replacement.
- The device is lightweight and equipped with a handle; the spot‑measurement button is located at the handle’s tip, making it easy to press for data acquisition.
VII. Principle Explanation
The measurement principle of the ultrasonic method is based on evaluating the changes experienced by ultrasonic waves as they propagate through a component due to scattering or reflection from internal features. Ultrasonic waves are generated at the component’s surface via the piezoelectric effect and travel within the material as elastic waves. As these waves propagate, they undergo scattering or reflection when encountering interfaces between media with differing acoustic impedances—for example, the interface between aggregate and matrix in concrete. A portion of the incident energy is backscattered by internal structures such as reinforcing steel or embedded conduits and returns to the surface, while most of the energy is reflected at the component’s bottom boundary, such as the interface between concrete and air.
To generate and record acoustic energy, ultrasonic testing equipment is equipped with various types of transducer elements, which can function as both transmitters and receivers and are connected to the ultrasonic system for measuring and displaying results. Depending on the specific application, the arrangement of transmitters and receivers may vary.
The probe of this device is arranged in a 3×8 configuration, with three probes forming a single channel; there are eight channels in total. The system performs full‑channel acquisition, enabling the simultaneous capture of 56 A‑scan traces per acquisition, as illustrated below. Starting from Channel 1, when Channel 1 serves as the transmit channel, the remaining channels function as receive channels, sequentially acquiring and processing the received signals. Once Channel 8 has completed its transmit cycle, data acquisition for that particular point is finalized. The entire process—from acquisition trigger to image reconstruction—exhibits rapid response.
If operation is possible only from one side of the component, the transmitter and receiver are mounted on the same side; this configuration is known as a reflective arrangement, and the inspection method employing it is called the pulse‑echo technique. Conversely, when access is available from both sides of the component, the setup is referred to as a transmission arrangement or through‑transmission testing. This equipment utilizes the pulse‑echo method. In the pulse‑echo technique, by plotting the recorded amplitude versus time, and given a known sound velocity, one can determine both the depth of a defect and the thickness of the component.
VIII. Measured Data
(1) Crack Defect Detection in Test Specimens
Note: In the image, the strong red reflection indicates a crack defect, approximately 150 mm deep.
(2) Thickness Measurement
Note: A strong red reflection is present at the bottom, corresponding to the interface between the concrete test block and the underlying substrate. The measured thickness is approximately 500 mm, which is consistent with the actual conditions.
(3) Honeycomb structure is not dense
Note: A strong red reflection signal appears at a depth of 350 mm, indicating a reflection associated with honeycomb‑type compaction defects.
