Eddy Current
Nortec 500
The Nortec 500 Series, Olympus NDT's newest eddy current flaw detectors incorporate a full range of features: internal balance coils, VGA output connector (for heads up displays, monitors, and projectors), and a USB interface for rapid information transfer. The Nortec 500 also includes PowerLink™, for automatic probe recognition and program set-up. Where weight is critical, the smaller battery lightens the instrument to 2.8 lbs (1.2 kg) while keeping the full VGA resolution and display size.
The Nortec 500 improves on previous Nortec eddy current instruments and is available in four configurations. Each configuration includes USB port and increased resolution with reduced noise. Internal balance coils allow use of inexpensive absolute probes without the need for external balance coil adapters. A built-in preamp adds extra gain when needed for difficult tests. VGA output allows for the addition of a optional "heads up display" allowing hands free operation. The optional remote-null adapter adds convenience by allowing the probe to be nulled and the instrument screen erased from the probe.
Nortec 2000
The Nortec 2000D+ offers a frequency range of 50 Hz to 12 MHz for applications ranging from detection of cracks in tubes or structures to the discovery of minute flaws in aircraft materials. Single or dual frequency operation, easy to use digital conductivity, and rotating scanner support make the flaw detector ideal for numerous aerospace NDT applications.
Customer-interchangeable displays offer excellent visibility in any lighting condition. A VGA output drives a heads up display for inspection where conditions may be cramped or a large desktop monitor or projector for classroom training. At less than 4 lbs (1.8 Kg), the rugged Foreign Object Debris (FOD) free case will survive harsh field and production environments. An adjustable tilt bail and anti-slip bumper allow the unit to be placed on just about any surface.
Bolthole Scanner
Olympus NDT's extensive line of high performance NORTEC Eddy Current scanners is available for use with Nortec Eddy Current Flaw Detectors. With a wide range of features consisting of speed ranges from 40 to 3000 rpm, frequency ranges from 100 Hz to 6 MHz, multiple connector types, and multiple probe types, NORTEC scanners offer a full range of application solutions. Some of the more common applications are: airframe hole inspection with or without fasteners, wheel bolt hole inspections, surface inspections, post production testing for cracks, tube plug testing, and low frequency inspections through multiple aircraft skin layers.
Eddy Current Probes
Advanced eddy current inspection requires the use of many different coil configurations. Absolute and differential coils are available in both bridge and reflection designs. Depending on the test, some are very small in diameter and others can be quite large. A compromise is usually made to give the best depth of penetration, greatest sensitivity to the smallest defects, and smallest coil diameter.
In addition to coil size and frequency, the physical shape of a probe contributes to a successful EC test. Flaw location and part geometry determine whether a standard probe can be used or if a custom design is needed. Because the coil must pass over the flaw or be in close proximity to it, the probe body requires accurate geometric specifications.
