The lightweight NORTEC 500 Series eddy current flaw detectors incorporate a full range of features such as internal balance coils and VGA output connector. Various models also include features such as conductivity and coating thickness, rotating scanner compatibility, and dual frequency.
The NORTEC 500 Series, Olympus' 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.
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 display to be projected or viewed on a standard computer screen.
The optional remote-null adapter adds convenience by allowing the probe to be nulled and the instrument screen erased from the probe.
Where weight is critical, the smaller battery lightens the instrument to 1.3 kg (2.9 lbs) while keeping the full VGA resolution and display size.
The NORTEC 500 delivers basic single frequency eddy current inspection including external outputs.
The NORTEC 500C adds digital conductivity and coating thickness measurement capability in addition to basic single frequency eddy current inspection.
The NORTEC 500S builds on the foundation of the N500C and adds the ability to use rotating scanners.
The NORTEC 500D adds dual frequency capabilities to all the functions of the N500S.
