2 independent measurement gates, monitoring the echo amplitude and the sound path distance
When using transverse wave to detect flaws, the depths of the second and third waves are
automatically calculated according to the slab thickness.
Perfect DAC/AVG curve functions, the curves change along with the changes of the gain, sound
path, and displacement.
2.2 Features of the instrument
The firm and durable instrument shell is specially designed for the hostile site environment.
31 copper screw nuts are inlaid in the hard plastic casing
Innovative rotating positioning bracket is easy to use.
The hand strap can be installed for both hands so that you can hold the machine with your left
or right hand.
The D-shaped ring on the instrument is convenient for installing a cheststrap.
The corrosive texture of the shell surface is scratch-resistant and beautiful.
Innovative high power lithium batteries of notebook style.
Full screen function,
the echo display area can cover the entire screen, which provide you with the
sense of the maximum window
Solid waveform displays,
the visual contrast of waveforms is increased so the undetection is hard
to happen when fast scan is carried out
Bulk storage,
up to 1000 data sets can be stored, including waveforms, curves, and parameters
(containing the traditional 1000 channels)
Echo-echo thickness measurement,
zero calibration is avoided, and the net thickness of the base
material can be directly measured through the coating
Squared ultrasonic pulse generator with changeable width and scope is initiative domestically.
It replaces the traditional method of matching probe by changing damping with adjusting the pulse
energy and pulse width. Thus, the probe can be exactly fit for the testing and the resolution and
penetrating power of the approaching surface can be enhanced significantly. It is specially fit for the
testing of large scale of forge piece, casting piece and non-metal with the requirement of higher
penetrating power and lower electric noise.
●
The voltage of the pulse generator can be changed between 50V to 400V continuously, so that no
matter thin plate or hard-penetrated work-piece can be matched with the most fitful probe.
●
The width of the pulse can be changed between 25ns to 1000ns continuously, so that the best
sensitivity can be realized with the help of different probes with different frequency.
Damping
can be changed among 4 levels: 33/50/100/500Ω, so that the best performance of the
probe can be attained and the different requirements of the sensitivity and resolution can be realized.
