Eddy Current Flaw Detectors

The Nortec 500 Series 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 a 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 built­in 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 1.2 kg (2.8 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.

using MIL-STD-810F, Method 511.4, Procedure 1

Absolute and differential in either bridge or
reflection configuration. The instrument is fully
compatible with Nortec PowerLink probes.

Can be set to trigger on positive or negative box,
polar, or sweep alarm settings

coating thickness

Up to 200 traces can be stored for recall. The
traces can be static or frozen and can contain
up to 60 seconds of movement. The traces are
stored with the date and time of capture.

Up to 200 instrument set-ups may be stored
and recalled. The date and time of storage is
recorded with each set-up.

Provides a custom configurable report header
containing the display screen data and probe
parameters including serial numbers
(PowerLink probes only).
