Immersion Ultrasonic Testing
Explain what an immersion ultrasonic test is and why they are needed in NDT. Another way to couple the sound from transducer to a test object is coupling the sound with water. This can be done with squirters where the sound travels through a jet of water or by immersing the transducer and test object in a tank of water.
Immersion Transducers - Olympus IMS
An immersion transducer is a single element longitudinal wave transducer with a 1/4 wavelength layer acoustically matched to water. Immersion transducers are specifically designed to transmit ultrasound in applications where the test parts are partially or wholly immersed in water, which allows a uniform and fast coupling technique for rapid ...
Immersion Probes - Olympus IMS
Immersion probes are designed to be used with a water wedge or in an immersion tank when the test part is partially or wholly immersed. They are longitudinal wave probes that can be set up for refracted shear-wave inspections using a Rexolite wedge.

Description: These are probes used for noncontact scanning methods using water as contact medium. They are applied in immersion tanks, so they must be waterproof. Many other scanning techniques use them as well, e.g., gap scanning, probe …
Precision Immersion Ultrasonic Probes for NDT Testing - IMG
Immersion ultrasonic probes are technologically advanced devices that are essential in non-destructive testing (NDT) processes. This diagnostic technique allows for the assessment of the integrity of materials and components without damaging them, revealing internal defects, inconsistencies, and thickness variations. Working Principle:
An Introduction to Ultrasonic Transducers for Nondestructive Testing
Immersion transducers, as the name implies, are designed to be immersed in water and use a column or bath of water to couple sound energy into the test piece. These transducers frequently incorporate an acoustic lens that focuses the sound beam into a small spot, increasing sensitivity to small reflectors.
In this work, we developed a novel high-precision ultrasonic immersion scanner to evaluate the full ultrasonic probe characteristics which include the squint angle measurement in three different reference planes (XY, XZ, and YZ), RF-signal and its frequency spectrum at water-steel interface, focal distance, focal range, focal width, focal length...
Immersion Probes for Ultrasonic Testing of Metals & Plastics
The SONOSCAN immersion transducers for Non-destructive Testing (NDT) are mainly used to test metals and plastics for the smallest material defects. For example, binding defects, welding defects or cracks and pores in metal parts can be detected. The powerful, robust ultrasonic probes can be connected to all common ultrasonic testing devices.
The new probe adapter LIUS for local immersion technique enables the application of immersion probes with frequencies of more than 50 MHz even in mobile systems. As a result, high-resolution tests, which can otherwise only be carried out in the immersion tank and thus in the laboratory, are also possible on site directly on the component.
Immersion PAUT Probes | Vermon NDT
Immersion probes are used for testing the thickness and integrity of materials. It is immersed in a liquid (typically water or coupling gel) that allows for the efficient transfer of ultrasound waves into the material being tested. They are commonly used in …
