PMT Protective membrane transducers are for use where coupling is difficult due to irregular surface conditions. The PM membrane will conform to surface irregularities for better coupling. Protective wear cap transducers are for use when scrubbing of the test material is necessary. The use of WC replaceable wear caps greatly extends transducer lifetime.  

1. Exceptional resolution, gain, and signal to noise ratio, well suited for inspection of weldments and joints.
2. Composite element provides higher damping and wider bandwidth when compared to standard element MST transducer.
3. Wedges designed with short index, perfect incidence angle, and low noise
4. Tool-free screw-on wedge design allows multiple purpose use for a single transducer

MST miniature shear wave transducers can be used with MSW screw-on style wedges, or MSH high temperature wedges for intermittent contact up to 500 F (15% duty cycle with 10 second maximum contact time).

MSC miniature shear wave composite element screw-on transducers are fully compatible with Megasonic MST series miniature shear wave transducers and use the same MSW and MSH (high temperature) wedges. MSC transducers take advantage of composite element technology for critical applications that require the higher damping than MST series.

1. Exceptional resolution, gain, and signal to noise ratio, well suited for inspection of weldments and joints.
2. Wedges designed with short index, perfect incidence angle. and low noise.
3. Removable wedge design allows multi-purpose use for a single transducer.
4. Full steel top plate for long transducer lifetime.
5. Continuous duty high temperature transducers are available upon request.
6. Straight BNC connector (SB) supplied unless otherwise noted

RST standard shear wave angle beam transducers are used with LSW standard wedges or HSW high temperature wedges for up to 900° F (15% duty cycle with maximum 10 second contact time). Cool to room temperature before reuse. 

AWS transducers meet AWS structural welding  code D1 .1 and are used with LSW .75" x .75" wedges. 

1. For use with all standard flaw detectors
2. Specifically engineered for very high gain to allow use where other transducers fail
3. Custom focal depth transducers are available
4. Durable metal case for long lifetime
5. Right angle Lemo connector is standard with other options available

MSF series angle beam transducers are designed for detecting 1.5 µm micro crack clusters in either pitch catch or pulse echo configuration. Broad bandwidth is standard but an 8 MHz centered narrow bandwidth transducer is an available option.

1. Rugged waterproof stain-less steel cases for long service life 
2. Acoustic impedance matched quarter wave epoxy facings for better gain, resolution, and sensitivity 
3. Focusing option for improved near surface resolution and increased sensitivity to small discontinuities 
4. Miniature and custom transducers available for tight quarters inspection or special purposes

IHM transducers are highly damped (Broad Band) for the highest resolution applications such as near surface flaw detection and thickness gauging.  

IMM general purpose transducers (Medium Band) have high signal to noise ratios for high resolution flaw detection in all materials.

ILT transducers are designed with exceptional penetrating power (Narrow Band) for good resolution flaw detection in acoustically lossy materials. 

IPM paintbrush style transducers have a wide scan area for rapid inspection. Flatness of the gain envelope is guaranteed to be less than ­+ - 2.0 dB.

Focusing is available when required, specify spherical or cylindrical focusing with focal length.
