¡¡¡¡WSD-3 digital
sonic instrument
¡¡¡¡This tool is our newly digital sonic tool, which is designed
and produced based on our experiences of many years of research
and manufacture of advanced sonic tool, and integrated with many
new electronic techniques such as pocket PC, blue tooth, 14 bit
high-speed A/D, superficial adhibition and multi-layered printed
circuit, and characterized by low-power, small-size, and light-weight.
It is controlled remotely by pocket PC, and flexible and fitted
for many complex engineering needs. It is mainly applied in non-metallic
material sonic and super-sonic inspection, such as concrete, rock
mass, core, porcelain, graphite. I can also be applied in intensity
inspection, structure interior bug inspection, fracture inspection,
joint surface quality inspection, homogeneity inspection, structure
thickness inspection, pier quality inspection, sonic log, and
elastic mechanic parameters inspection.
Features
- Portability and flexibility¡ª¡ªcombining transmitter and receiver
together, small and light.
- Blue technique, wireless remote control¡ª¡ªPocket PC controlled
central unit by Bluetooth technique, remote control is effective
within 10 m. All parameters and measurement display can be
fulfilled easily wirelessly.
- Pocket PC control, Powerful function¡ª¡ªall Chinese pocket
PC support the man machine interface and sampling control,
parameters setting, data display and storage, graph plot,
image making, Field works are very easy.
- Extendable easily¡ª¡ªwaveform sampling and storage are all
controlled by pocket PC. Data management is easy and software
is easy to be extended.
- Powerful pocket PC¡ª¡ªbeside the high hardware configuration,
pocket PC is installed with many utility software. User can
arrange the date, navigate the web via wireless net, and use
WORD, EXCEL, PowerPoint, and Media Player for office and amusement.
- Operation convenient and quick¡ª¡ªall Chinese display, friendly
menu design, only option and hand writing.
- Wide band and low-noise¡ª¡ªas high as 500kHz band pass, first
arrival is clear and complete.
- Early sampling¡ª¡ªdata before trigger can be sampled easily,
it is convenient for first arrival recognition.
- Super strong anti-interference ability¡ª¡ªsignal channel
provides 3 band pass with multi high or low pass filters,
This filter can suppress certain interference.
- Automation¡ª¡ªtime delay can be determined automatically,
first arrival traveling time and amplitude can be sampled
automatically.
- Large storage¡ª¡ª512MB CF card (extensible), can store kinds
of data and waveform for indoor analysis
- Low power loss, flexible power choice¡ª¡ª it can be power
by AC or DC, and built-in rechargeable battery which can last
for more than 30 hours.
- All Chinese Windows based analysis for PC or note PC: multi-function,
easy operation, generate three testing reports (confirming
the rules by China Ministry of construction).
