US-SMART
On ANDROID systems – wireless –
The US-Smart
allows a ultrasonic wireless control using the bluetooth
between the
couple probe / US Smart and your tablet or smartphone.
By using the
US-Smart, you’ll have the possibility to make statements
of measures
until
This device can
also allows to realize various kinds of inspections such
as welds, rails inspections, composite
materials…
General Description
The US-Smart is a unique worldwide device due to the BLUETOOTH
connectivity
and its ANDROID environment
.
This
ultrasonic device is powered supply via battery Li-Ion.
His main
quality is its small size and its ‘ready to use’ concept.
The
US-Smart has been created to simplify the NDT controls.
The
transmitter can generate pulses with a voltage level and
a width
programmed by the user. A low noise preamplifier
combined
to a VGA gives a gain range between 0 and 80 dB, a DAC
curve is
also available. A 12 bits analog digital converter with a sampling
frequency
of 80 MHz is used to digitize ultrasound signals.
The
device has 2 working modes : Transmission or Reflection.

Software
To get menu slide your finger from the left
to the right
On the top of the screen or on the
left-bottom part.
Gain : control the receiver amplifier Gain
You can adjust the gain with the menu on
left
Add /take off 3 / 1 / 0.1 dB or give the gain
Or put your finger on the screen and move
it to the top.
Scale : control the sampling time
You can adjust the time/div with the menu
on the left
Add /take off 1 / 0.2 / 0.05 µs/div
Or put your finger on the screen and move
it.
Delay : control the sampling delay
You can adjust the sampling delay with the
menu on left
Add /take off 10 / 1 / 0.1 µs
Or put your finger on the screen and move
it.
Gates : give you access to the three gates
of control to measure
-
the amplitude into the gate
-
the distance of the echo
-
some alarme
you have access to three gate (1/2/3) that
can be controle in position, width and height.
Position will allow you to place the start
of the gate.
Width will allow you to adjust the width of
the gate
Transmitter give an access to differant
parameters :
-
Voltage : amplitude of the
transmitter pulse 0/-230V
-
Frequency : 1 to 20 Mhz (
centrale frequency probe)
-
Pusle Repetetivity Frequency
( 200Hz to 10Khz)
-
Single/double crystal
(depending of your application)
Transmitter Voltage
set the amplitude of the transmitter pulse
0 to -250 V
Transmitter
Frequency : set the width of the pulse ie the centrale frequency of the
transducer
TGC
curve : allow
to change the gain during the acquisition
CAD
: display amplitude – distance curve
THRESHOLD : all the ascan data under a thershold
will be set to 0. The threshold value can be adjust .
MEASUREMENT
UNIT/VELOCITY : set the ultrasound speed and specify
the display unit (mm or µs)
SIGNAL
ANALISYS TOOLS: alow you to add cursor to measure distance/amplitude on the ascan.
SAVE/RECALL : save or recall some configuration.
OPTIONS:
Control / Probe /Filter / Display Speed / Gate option / System option access
Control : allow you to set the reference amplitude
value, the reference gain and thickness
Probe : allow you to set the angle of the
probe , add some delay.
Filter : select the filter for the receiver
, a FIR filter will be applied on rf data.
Display
speed
Gate
Option : fill the zone between the origin axis
and the gate or between the two gate.
System : allow to setup some option , color of the ascan or the langage…..
QUIT
: leave the Us-smart apk.
