The Sonatest LMA series features large, angle beam shear wave contact transducers engineered for robust ultrasonic non-destructive testing. Designed with a rectangular lead zirconate titanate crystal and medium damping for medium bandwidth, these transducers provide reliable flaw detection across a variety of industrial applications.
Key Features:
Single Angle Beam Design: Dedicated shear wave contact transducer for angled beam ultrasonic inspections.
Lead Zirconate Titanate Crystal: Equipped with a large rectangular crystal measuring 20 x 22 mm (0.787 x 0.866″) for excellent acoustic output.
Medium Damping: Balanced to provide medium bandwidth signal performance and penetration.
Operating Temperature: Suitable for operating environments with a maximum temperature of 50°C (120°F).
Common Applications
Inspection of general welds
Examination of tube and pipe structures
Quality evaluation of forgings
Flaw detection in castings
