Description:
TFScan
6 is an ultrasonic thickness measurement and flaw detection
system for production line inspection and automatic quality control.
The system includes:
- transducers
and wedges
- an
inspection scanner, or a immersion tank with motion control hardware
- an
industrial computer containing DSPUT5000 board, and some DT16/DT8
pulser/receiver boards
The
on-board digital signal processor (DSP) runs up to 4,800,000,000
instructions per second. With this powerful DSP chip the system
can process all the data in real-time. The output pins can be programmed
to respond the flaw conditions in order to control the external
devices such as alarm, paint sprayer, and production machines. All
the tests can be programmed to sense the input pins before triggering
the alarm. This feature can be used to report the status of the
automatic transducer rising mechanism: up or down. The system can
be equipped with up to 256 channels.
TFScan
6 software consists of two packages: basic package and advanced
package. The basic software package is just like a multi-channel
flaw detector. The user can define up to 256 tests with different
parameters such as transmitting channel, receiving channel, gain,
gates, pulse width, and so on. Each test can be set to thickness
measurement or flaw detection. The thickness measurement can be
defined to trigger the output pin if the thickness is below or above
a limit. The flaw detection can be defined to trigger the output
if the signal is higher or lower than the predefined threshold.
Each test will have its own scope window to show the ultrasonic
signal and the gates. Pulse Repetition Rate can be defined from
1 to 5000 Hz (20,000 Hz optional) and the system will go through
all the tests at each time event.
The
advanced software package provides the user with more features such
as encoder coded B-scan, TOFD, C-scan, data recording, and powerful
script programming. With this advanced software package all the
data can be saved on a hard disk and read back later for review.
The B-scan display can be drawn based on time and the position of
the transducers coded by a quadrature encoder. By using the script
programming technique the end user can write his own inspection
program to follow a special inspection procedure and to generate
customized report.
A
translation file can be modified to support the international languages
provided by Windows. Other programs are also provided to control
a scanner or an immersion tank.
