Ultrasonic Pulse Velocity Tester
Ultrasonic Pulse Velocity Tester measures the integrity of concrete, rock, and other materials by sending high-frequency ultrasonic pulse waves through materials, measuring the time taken for the waves to travel, and detecting cracks or defects when the sound waves are disrupted without causing damage.
The principle behind Ultrasonic Pulse Velocity Testing is based on the fact that sound waves travel faster through denser and more homogeneous materials. Cracks, voids, and other defects in the material will disrupt the path of the sound waves, causing them to travel more slowly. By measuring the travel time of the waves, Ultrasonic Pulse Velocity Tester can detect these irregularities and provide valuable information about the condition of the material being tested.
Ultrasonic Pulse Velocity Testing is commonly used in construction projects to assess the quality of concrete structures such as bridges, buildings, dams, and tunnels. It helps engineers and inspectors identify potential weaknesses or defects in the material, allowing for timely repairs or reinforcement to ensure the structural integrity and safety of the infrastructure.
Quick detection of the integrity of foundation piles continuous wall with Ultrasonic penetration method.
Application of Ultrasonic Pulse Velocity Tester
- For testing the integrity of the foundation pile (”Pile Test”)
- For testing the compressive strength of concrete (”Strength Test”)
- For testing defects and cavities in cultural members (”Defect Test”)
- For testing the crack depth of concrete surface (”Crack Test”)
Features of Ultrasonic Pulse Velocity Tester
- The test result is available and the graphic distribution of abnormal points in each profile is shown at any time.
- The sampling delay and amplification factor may be adjusted at any time.
- With true color highlight LCD, waveform, wave speed, and amplitude of multiple tested profiles may be clearly observed on-site data, curve, wave train figure and schematic graph of pile integrity of all test points in all profiles may be checked at any time, the quality of the whole pile in the test is very clear.
- It adopts a WinCE operation system with a press screen and user-friendly interface, which is simple, easy to learn, and convenient to operate.
- With a high-capacity SD Card, there is no need to worry about the storage space of test data
- Built-in high-performance and capacity lithium batteries may satisfy fieldwork for a long time.
- Various USB ports may be used for data transmission or software updates within the instrument or external units such as a mouse or keyboard.
- Test data of the same project is saved under the folder created with the title of the project for easy and reliable management.
