C-scan images

Dear experts and acedemissions,

I want to learn technical information about c-scan system.
What is the basic principles of this system.
is there any differency of using probe ?
please inform me

Re: C-scan images
I assume you are talking about C-Scan Images as in Ultrasonics and not in pipeline Current Mapping?

UT C-Scan is simply a data presentation method where by you plot X and Y positional information (usually provided by some form of probe manipulator)plus the UT signal data whether it be depth, amplitude or time of flight whatever signal component you are interested in. You can then apply color or other media to represent information at various signal levels to produce maps of the area or component under examination.

Of course once data is stored as co-ordinate and signal measurements in a computer you can apply a myriad of graphing or display tools to produce the desired image results.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.

...
oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
