This
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.
Chart
records of ultrasonic shear wave and compression wave results
Single
bar graph for loss of back wall echo
Table
for each test of flaw responses above the set threshold showing
position and signal amplitude
Positional
plotting readout from encoder/s
Recording
and recall of set-up and test results
Can
be customised for specific inspection system requirements
This
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.
The
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.
The
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.
General
Specification
| Number
of Channels: |
Maximum
of 32 analogue channels. |
| Input
Voltage range: |
Nominally
0 to 5V unidirectional. |
| Frequency
response: |
In
excess of 10KHz per channel. |
| Data
Entry: |
Typically
including:
Product
serial number.
Job reference.
Date of
inspection.
Inspector.
Additional
information as required.
|
| Product
Numbering: |
Entry
of specific product number for a single product inspection.
Entry of a sequence of numbers for batch inspection.
Entry of the first serial number with subsequent product numbers
automatically incremented. |
| Y
Axis Scaling: |
Selection
for each channel of 0 to 100% scale positions based on the
input voltage fro that channel. |
| Flaw
Threshold: |
Independently
set threshold for each channel.Automatic threshold level calculated
from a statistical algorithm. |
| X
Axis Scaling: |
Operates
in time mode for unidirectional plotting of the charts.
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. |
| Print
Outs: |
Options
to print single test reports or batch reports.
High speed testing of many product may necessitate storage
and recall from printing when buffer store is full. |
| Storage
of Records: |
Chart
records stored to floppy disk, hard disk or CD.
Manual operation of chart using keypad entry or remote switch.
Remote operation by operator or proximity detectors. |
