OPTIMA Contact Transducers include Standard Contact for thickness gaging applications where rough handling is expected and Fingertip models where smaller size or maximum resolution and higher frequencies are required. Delay Lines are for precision thickness gaging and near-surface flaw detection, while Dual Element are for use with instruments having isolated pulser/receiver connections. Protected Element models are for use on rough, uneven, abrasive or hot surfaces.
Standard Contact Models
OPTIMA Standard Contact transducers are designed for applications where rough handling is expected. where access is not limited, and/or relatively large element size is needed. These units are commonly used on millfinished wrought metals, forgings, extrusions and castings, or rough-machined materials.
Fingertip Case Models
OPTIMA Contact Fingertip transducers are for general purpose use where larger contact transducers won't fit, or where maximum resolution and higher frequencies are needed. With smaller elements and case sizes, these precision fingertip transducers can be used on somewhat smaller contour curvatures than our larger standard models. Best results for precision flaw evaluation will be obtained when used on relatively smooth surfaces.
Delay Line Models
OPTIMA Delay Line Contact transducers have primary applications in precision-thickness gaging and for nearsurface, high-resolution flaw detection. Relatively smooth surfaces and fairly thin test objects are generally required for best results.
Dual Element Models
OPTIMA Dual Element transducers produce improved near- surface resolution when compared with normal single element contact transducers. Used on instruments having isolated pulser/receiver connections (through transmission mode on many instruments), each of the elements functions independently, one as a transmitter, the other as a receiver.
Protect Element Models
OPTIMA Protected Element transducers can be fitted with three different types of
replaceable protective faces. Used interchangeably, these protective faces extend the use
of a single transducer for flaw detection in materials having rough, uneven, abrasive or
hot surfaces. Relatively large element sizes and low-to-midrange frequencies are combined
to produce high-energy transducers with high-penetrating abilities.
