NM01SMA445

The Sonatest SMA4-45 is a small, single element angle beam shear wave contact transducer designed for effective ultrasonic inspection at a refracted angle of 45 degrees in steel. Featuring a secure Lemo 00 connector for reliable connection to your Sonatest or compatible instrument, this transducer operates at a nominal frequency of 4 MHz.  

The "small" designation in the SMA series indicates a compact 8mm x 9mm rectangular crystal. This smaller crystal size allows for inspection in tighter geometries and offers a more focused beam for detecting smaller reflectors. The 45-degree refracted angle is a versatile choice for detecting various weld flaws and other angled beam techniques. The higher 4 MHz frequency provides enhanced resolution for identifying smaller discontinuities.  

Key Features:

• Single Element, Angle Beam (Shear Wave): Designed to introduce a shear wave into the test material at a specific refracted angle.  

• Refracted Angle in Steel: 45 degrees - A versatile angle for various inspection techniques.  

• Frequency: 4 MHz - Offers higher resolution for detecting smaller defects.  

• Small Crystal Size: 8mm x 9mm rectangular crystal allows for inspection in confined areas and provides a more focused beam.  

• Connector: Lemo 00 - Ensures a secure and reliable connection to compatible ultrasonic instruments.  

• Manufacturer: Sonatest - A reputable manufacturer of high-quality ultrasonic testing equipment and transducers.

• Medium Damped: Typically medium damped for a good balance of sensitivity and bandwidth suitable for general-purpose flaw detection.  

Benefits:

• Versatile Angled Beam Inspection: The 45-degree angle is suitable for detecting a range of flaw orientations in welds and other components.

• Good Resolution for Smaller Defects: The 4 MHz frequency enhances the ability to identify smaller discontinuities.

• Compact Size for Limited Access: The small crystal dimensions enable inspection in areas with restricted space.

• Reliable Signal Coupling: Designed for direct contact testing with appropriate couplant.

• Secure Connection: The Lemo 00 connector ensures a stable and noise-free signal transmission.

• Wide Range of Applications: Suitable for various materials and component sizes requiring angled beam inspection where good resolution is needed.

Applications:

• General weld inspection for detecting various flaw types.  

• Inspection of castings and forgings for internal defects oriented at an angle, especially in tighter areas.  

• Examination of pipes and tubes where access is limited.  

• Flaw detection in a variety of materials requiring a high angle beam approach with good resolution.
