TRL / SE Arrays (Separate Transmit Receive)
- Wrought / cast stainless steel components,
- Dissimilar metal welds
- Clad components
- Safe end / sub clad of nuclear vessel
- Pressurised welds
Thanks to the acoustically isolated transmit and
reveive transducers, the emitted wave does not interfere with the
received wave, allowing a reduced blind zone under the surface,
and a better signal to noise ration for the inspection. The angle
between transmit and received transducers helps to reduce the level
of back scattering echoes.
The transmit and receive transducers can be of various
No possible variation on refracted angle and focusing
Linear transducers allow a variable refraction angle.
Matrix transducers also allow the beam crossing depth to
be varied or the beam to be deflected laterally
TRL/SE probes can be either integrated or with removable
Both concepts can be used with monolithic, linear or matrix probes
they are dedicated to industrial use with fixed
configuration. They are more compact and easy to handle with a scanner,
but the wedge angle and transducer position are fixed.
Removable transmit and receive probes
are more flexible as the wedge geometry and transducers position
can be changed by changing the wedge.

corresponding to your application.
- Possibility of steering and skewing (matrix only) the beam
- Absence of dead zone
- Focusing effect in the beam crossing region
- Improvement of defect response
- Reduction of the backscatter signal
- Improvement of signal to noise ratio
- Frequency from 500 kHz to 5 MHz
- Unlimited number of elements, typically 2x16 to 2x64
- High S/N ratio and optimized pulse length thanks to acoustic
matching to wedge material (Rexolite, Plexiglas, PEI, etc)
- High acoustic insulation between transmit and receive sides
- High reliability over time thanks to a robust, watertight design,
compatible with difficult industrial environments
- Housing customized for the mechanical environment (inspected
parts, scanner, wedges, etc)
- Customized connection
- Adaptation to a particular environment (temperature, pressure,
radiation, chemical compatibility)
- Halogen-free for nuclear environments
- Water inlets
TRL Probe Design
can help you to design your TRL probe, and particularly the
incidence angle, roof angle and distance between transmit
and receive transducers to reach the targeted focal zone with
the desired refracted angle.
We can also simulate in detail the beam crossing area to
evaluate the detection and sizing capabilities of the probes.
With the customer's agreement, IMASONIC can collaborate with
partner companies with experience in inspection methods based
on TRL probes, to offer already-qualified solutions for various
