UNIWEST’s US-454A eddy-current instrument offers single- and multi-frequency eddy current (EC) inspection, reliable signal-to-noise ratio, frequency mixing capabilities, USB and Ethernet data storage capability, and exceptional digital strip chart data collection, all with the supplier’s EddyView color display. It states that the 454A’s signal-to-noise ratio “redefines NDE inspection in the field, the lab, and wherever high level, accurate eddy current testing is needed.” The signal-to-noise and filtering capabilities allow for inspection in applications outside of the scope of portable eddy current equipment.
The 454A’s primary advantage is its ability to be integrated into an automated system. Control of the US-454A with the USB or Ethernet, as well as the dual encoder position input, makes it an ideal instrument for systems. The field-proven features of the direct access keys, control knob and large, bright colored display makes it user-friendly for entry-level NDT technicians.
Designed for optimal system compatibility, the 454A is being used in aerospace (engines and airframes), power generation, and automotive manufacturing, and in general eddy-current applications. Because the instrument offers encoding and communications capabilities, excellent signal-to-noise ratio, and four frequencies, it is more easily integrated into specialty systems.
The 454A is a lightweight, hand-held, battery-operated instrument that can be connected to a laptop, PC, and motion controllers for use in semi- or fully automated data collection applications--such as surface inspection of aircraft fuselages or measurement of critical engine wear using a 32-element probe. Two encoder inputs enable position stamping of data. Pulse-on position input is ideal for motion control applications, in which mechanical devices move a part past a sensor and mark the location of any detected flaw for further evaluation. Such is the case in testing of critical aircraft engine components. Ethernet and USB capabilities enable instrument control, along with time- and position-stamped data transfer to the computer.
