UniWest introduces the EVi eddy current testing system, a portable, high precision, operator-friendly eddy current system. The EVi augments UniWest’s signal to noise ratio technology with real-time imaging of the surface under inspection. The result is a surface flaw detection system that provides conventional eddy current charts, graphs or plots, in multiple display modes, alongside a real-time visual image of the surface area under inspection. For operators, the accessible on-screen information speeds discernment of surface conditions at the same time it greatly improves detection of cracks and other discontinuities, according to the company.
The EVi system is fully compatible with all UniWest scan probes and accessories as well as many other compatible devices. The EVi also offers capabilities for bolt-hole, surface, flush-rivet, weldment and interface scanning. When used in conjunction with UniWest’s ECS-5 Bolt-Hole Scanner, the EVi enables full surface imaging bolt-hole inspection of previously inaccessible surface areas, including complex, multi-stack and multi material stack-ups. Together, the EVi/ECS-5 provide rotary and linear scan-motion indexing at scan resolutions between 3 and 30 mil in one mil increments. Scan motion indexing can be applied at rotations between 500 to 3000 RPM, adjustable in 10 RPM steps, at constant torque throughout the speed range.
When used with UniWest’s ECS-3S Handheld Scanner the EVi enables full-surface scanning of previously inaccessible, remote and obscure surface areas. Ergonomically designed for comfortable handling and rapid inspection of small and hard to reach areas, the ESC-3S scanner provides a constant, high-speed scan of the surface. The ECS-3’s contour-following sensor assembly allows inspection of variable surface gradients, including detection of cracks and other discontinuities around flush-rivets and fasteners, as well and under paint. The ECS-3S provides surface scanning of friction stir-welds and surface weldments as small as .75 in. at frequency ranges between 20 kHz and 10 MHz.
Designed to minimize human intervention, the EVi eliminates operator setup and calibration with automatic connect-and-scan functionality. The unit automatically recognizes operating parameters of scanners and accessories. Accessory parameters such as motor voltage and encoder resolution are set automatically upon connection. EVi data is distributable via USB, Ethernet, VGA via USB adapter, OSB/OTG, Multi I/O, Analog X/Y or USB Keyboard. The EVi display accommodates multiple display modes including surface imaging, impedance planes, oscilloscope, strip charts and many other data display formats.
