chart recorder package can interface to a new or existing ultrasonic,
eddy current systems or combination of both. It can be supplied
to work with the existing ultrasonic flaw detector system or a
new PC based system can be supplied.

software package is a general purpose one for ultrasonic and eddy
current data presentation and defect analysis package. It can
support up to 32 analogue input channels, which may come from
an ultrasonic instrument, eddy current instrument or a combination
of the two.
data capture rate is such, that most NDT applications will present
no problem to the system. Therefore the system is suitable for
the very high speed pulses that are commonly encountered on on-line
bar and tube NDT inspection systems.
system provides a real-time display of the data from each of the
signal channels, and has both the option to save the captured
data, and to print out test records. Where products are inspected
in batches then the first product can be given a specific number
and subsequent products are sequentially numbered.

Selectable time base which operates on all channels to give
a displayed chart length corresponding to 1 second to 250
second of testing time.
High speed time bases can be used for local interrogation
of calibration standards and specific indications and lower
speed time bases for normal scanning.
Optional bi-directional scan.

Remote operation by operator or proximity detectors.
chart recorder package has been used in the following applications:
Inspection of bar products, using a rotating ultrasonic probe.
of tube and bar products, using a spiral drive mechanical arrangement
system for heavy walled tubes and short billets
of Coiled duplex tubing using an ultrasonic rotating probe
of submerged arc welded pipes
of drill pipe ends
of gas cylinders
typical display for a 5 channel system is shown above.
