The ULSO Linear Phased Array Probe is a high-performance ultrasonic transducer meticulously engineered for advanced non-destructive testing (NDT) applications. This probe incorporates a linear array of 32 individual piezoelectric elements, each addressable and controllable by a compatible phased array instrument, enabling sophisticated beam manipulation. Operating at a center frequency of 2.25 MHz, this probe offers a robust balance between the depth of penetration achievable within a material and the resolution attainable for detecting and characterizing subsurface features.
A key characteristic of this probe is its element pitch of 0.75 mm, which denotes the center-to-center spacing between adjacent elements. This finer pitch, compared to probes with larger pitch values, generally facilitates wider and cleaner electronic beam steering capabilities with a reduced likelihood of generating unwanted grating lobe artifacts. It can also contribute to improved resolution along the scanning axis. The probe's elevation, representing the active aperture dimension in the non-scanning plane, is a substantial 24 mm. This larger elevational aperture results in a more tightly focused and less divergent ultrasonic beam in the elevational direction. This enhanced focusing yields several benefits, including increased sensitivity to planar defects oriented parallel to the scanning direction, improved lateral resolution in the non-scanning plane, and a potentially better signal-to-noise ratio by minimizing the reception of off-axis scatter.
The transducer is housed in an A5 housing, a specific mechanical design likely provided by ULSO, which may be dimensionally different from other housings to accommodate the larger elevational dimension. It is equipped with a 2.5-meter PVC cable, ensuring a durable and flexible electrical connection to the phased array system. The inclusion of an IPEX connector, a miniature coaxial RF connector often used in smaller electronic devices, suggests potential compatibility with specific, possibly more compact or specialized phased array instruments rather than standard industrial UT connectors like Lemo.
Manufactured by ULSO, a recognized provider of ultrasonic NDT solutions, this linear phased array probe empowers users with advanced inspection techniques. These include electronic scanning, allowing for rapid coverage without physical probe movement, and dynamic beam steering and focusing, enabling optimized interrogation of the material from various angles and depths. These capabilities are crucial for detailed flaw detection, accurate sizing, and comprehensive material characterization across a wide range of industrial applications.
