EVi Advanced Eddy Current Flaw Detector

EVi is UniWest's most technically advanced and operator-friendly portable Eddy Current Testing (ECT) / Eddy Current Array (ECA) system ever offered.

The EVi works directly with the UniWest family of Standard probes and accessories, as well as eddy current array (ECA) probes up to 128 elements. UniWest’s unmatched selection of standard and advanced display features set a new standard for flexibility of applications, ease of use, interpretation of data and overall operator accuracy.

The key to the EVi’s ground-breaking performance is the display of a visual image of the surface area under inspection alongside the customary and selectable eddy current signal displays (impedance plane, A-scan or strip charts).

The EVi provides a high precision, easily readable display of surface conditions enabling improved interpretation of data while giving more accurate discernment of cracks, pits, gouges and fretting.

By merging innovative surface imaging with UniWest’s renowned, best-in-class signal to noise, the EVi system sets a the standard of precision for eddy current testing in a portable and easy to use package.

Scanners designed exclusively for use with the EVi

ECS-5

The ECS-5 is UniWest’s EVi-compatible, hand-held bolt hole scanner. Ideal for rotary and linear scan-motion indexing. The ECS-5 supports both absolute and differential coil types in both reflection and bridge configurations. Variable rotation from 250 to 3800 RPM is adjustable in 10 RPM steps at constant torque throughout any speed range.

ECS-3

Ergonomically designed for comfortable handling and rapid inspection of small and hard to reach areas. The portable ECS-3S scanner provides a constant, high-speed scan of the surface. Capable of covering areas as small as ¾ inch, the ECS-3S’s contour-following sensor assembly allows inspection of variable surface gradients. The ECS-3S improves flaw discernment for previously inaccessible remote and obscure surface areas.
