Ultrasonic Contact Transducers

Typically used for manual inspections, straight beam single element transducers are ideal for scanning parts with regular geometry and relatively smooth contact surfaces. This includes flat or curved surfaces where you need to identify flaws or a backwall parallel to the surface or detect with a beam normal to the surface. With improved near surface resolution, you can use these probes along with a couplant layer (typically gel, oil, or paste) when you need to penetrate a thick section of material.

Straight beam dual element (TR) transducers are best for manually scanning thin sections of material when looking for flaws or backwalls parallel to or those which are detectable with a beam normal to the surface. With excellent near surface resolution and reduced noise caused by scattering, these probes transmit and receive elements separated by a crosstalk barrier. They can be contoured and coupled on curved and rough parts and surfaces and do require a couplant layer, typically a gel, oil or paste.

For European Customers: Probe models have side mounted Lemo 00 connectors, side mounted Microdot SEB..KF types

For North American Customers: Probe models use fixed BNC cable (ADP) or side mounted MMD (FDU)

Angle beam probes are preferred for parts with inclined flaws, such as welds, and are sometimes used in mechanized or automated testing. They use refraction to transmit shear or longitudinal waves at a predetermined angle, while most standard transducers generate shear waves by mode conversion. Elements are mounted on integral or replaceable wedges, requiring a couplant layer, typically a gel, oil or paste.

Our angle beam probes are available in both single and dual element types, and in multiple sizes.
