NM01C00224
The Dolphitech TRM-BEx-2.5MHz (no coupling) is a 2.5 MHz Transducer Module (TRM) belonging to Dolphitech's matrix array (2D array) series. It features a 128x128 element configuration (16,384 elements) and a 32 x 32 mm aperture, designed for use with Dolphitech's advanced ultrasonic imaging systems.
The "(no coupling)" designation indicates that this specific transducer is intended for use with a delay line or stand-off, rather than direct contact with the test piece. This configuration is often preferred for specific applications where optimized performance is achieved through the use of irrigation or specialized delay line materials.
The 2.5 MHz center frequency makes this transducer particularly well-suited for inspecting thicker sections and lower-grade composite materials, including GFRP, out-of-autoclave CFRP, as well as thick, coarse-grained metals. It offers good penetration capabilities for typical component thicknesses ranging from approximately 1 to 50 mm (material dependent). The matrix array technology enables high-resolution 3D ultrasonic imaging, providing detailed insights into the internal structure of the inspected component.
