Standard Transducers

Model CR Standard Contact Transducers

 

The larger element sizes of Model CR provide greater scan widths and penetration for applications such as plate, billet, bars, thick-section parts, pipe, and tanks. They have side-mounted BNC connectors and removable comfort grip to reduce operator fatigue. GP Series* offer the best combination of sensitivity and resolution.

Model F Fingertip Contact Transducers

 

Model F are small diameter transducers with side-mounted Microdot connectors. GP series* offer the best combination of sensitivity and resolution for most applications. HR series* are highly damped for applications where high resolution is required. C series* have piezocomposite elements and offer superior penetration in highly-attenuative materials. All Model F transducers feature an ergonomic design for improved operator control and comfort.

Model DFR Fingertip Delay-Line Transducers

 

Model DFR are small-diameter delay-line transducers with side-mounted Microdot connectors. Removable delay lines and highly damped piezoceramic elements enable measurement of very thin parts or detection of small near-surface flaws. Delay lines can be contoured for improved coupling to I.D. or O.D. curved parts. Custom sizes and shapes also available upon request.

Replaceable Delay-Line Pencil Probes

 

Pencil probes are designed for applications requiring a very small contact face, such as curved turbine blades or thickness measurement from the inside of a pit. They can be used with most flaw detectors and precision thickness gauges. Interchangeable delay lines are tapered to tip diameters of 0.065 inch (1.7 mm) and 0.090 inch (2.3 mm). Replaceable delay lines are available in packs of 10. The straight model features a removable handle, which also allows it to be used as a fingertip probe. All models have Microdot connectors.

Model DU Dual-Element Contact Transducers

 

Model DU are general purpose dual-element transducers with side-mounted microdot connectors. Replaceable/interchangeable delay lines and cross-talk barriers greatly extend versatility, cost-effectiveness, service life, and can be contoured to fit I.D. or O.D. curved surfaces.

Model ADP Dual-Element Contact Transducers

 

Model ADP are small-diameter, low-profile transducers with 2 fixed co-axial cable and BNC connectors (also available with Lemo-00 upon request). They are especially suitable for flaw detection and thickness measurement on pitted, curved, and irregular surfaces. Because the elements are mounted on internal delay lines they can be contoured to fit I.D. or O.D. curved surfaces.

Angle Beam Transducers AWS, SWS, QS, MSWS

 

  • Model AWS transducers and wedges meet the requirements of American Welding Society Structural Welding Code D1.1 and Bridge Welding Code D1.5. Transducers are available with piezoceramic elements (GP series*) and piezocomposite elements (C series*).

  • Model SWS are designed for general weld inspection and other applications such as pipes, tanks, pressure vessels, forgings, and castings. They have top mounted BNC connectors and are available with piezocomposite elements (C series*). Interchangeable acrylic wedges provide maximum versatility and service life.

  • Model QS features Quick Swap screw-in wedge attachment. They are available with top-mounted Microdot (MD) or new MCX low-profile swivel connectors. Piezocomposite (C series*) offer superior penetration and signal-to-noise ratio in highly-attenuative and coarse-grain materials.

  • Model MSWS have captive screws for wedge attachment and angled Microdot connectors for applications requiring low profile. Piezocomposite (C series*) offer superior penetration and signal-to-noise ratio in highly-attenuative and coarse-grain materials.

Model MWB+/MWK+ Angle-Beam Transducers

 

Models MWB+ and MWK+ are small transducers with side or top-mounted Microdot connectors and integral wedges for maximum versatility. GP Series* (MWB+) offer the best combination of sensitivity and resolution. C series* (MWK+) with piezocomposite elements offer superior resolution, penetration, and signal-to-noise ratio in highly-attenuative and coarse-grain materials such as austenitic stainless steel or cast iron.

TOFD Angle-Beam Transducers

 

Time-Of-Flight Diffraction (TOFD) is a method used to determine the size of cracks in metallic welds. It requires highly-damped, broadband transducers and wedges that generate refracted longitudinal waves (L-waves). SNI’s TOFD transducers have state-of-the-art piezocomposite elements (C series*) and Quick Swap screw-in wedge attachment. Straight-mounted connectors are Microdot (3/8-32) or Lemo-00 (M12 case).

Immersion Transducers

  • Model I1 are small-diameter, pencil-type transducers with straight-mounted Microdot connectors. Because the connectors are not waterproof, sealing with non-water-soluble grease is recommended. GP series* offer the best combination of sensitivity and resolution for general applications. HR series* are highly damped for applications where high resolution is required. C series* have piezocomposite elements and offer superior penetration, resolution, and signal-to-noise ratio in highly-attenuative and coarse-grain materials.

 

  • All model I2, I3, and I4 transducers have straight-mounted waterproof UHF connectors. Available I2 element diameters are 0.25, 0.375 and 0.5 inch (6, 10, and 13mm). I3 have 0.75 inch (19mm) and I4 have 1.0 inch (25mm) element diameters. GP series* offer the best combination of sensitivity and resolution for general applications. HR series* are highly-damped for applications where high resolution is required. C series* have piezocomposite elements and offer superior penetration, resolution, and signal-to-noise ratio in highly-attenuative and coarse-grain materials.

  • Model IR transducers have right-angle-mounted waterproof UHF connectors and small case design for applications where space is limited. Available element diameters are 0.25, 0.375, and 0.5 inch (6, 10, and 13 mm). GP series* offer the best combination of sensitivity and resolution for general applications. HR series* are highly damped for applications where high resolution is required. C series* have piezocomposite elements and offer superior penetration, resolution, and signal-to-noise ratio in highly-attenuative and coarse-grain materials.

  • Paintbrush Transducers are single-element immersion transducers which give a greater scanning width than conventional transducers with round or rectangular elements. They are often used in scanning tanks where large plates, bars, and other parts are tested which have large surface areas. Their large coverage decreases scan time dramatically. Like other conventional probes, they can be ordered with GP*, HR* or C* performance and are available in flat or cylindrical focuses.
