KEYFEATURES
CBD350 Portable Ultrasonic FlawDetector with hi-resolution color TFT LCD display.
The background color and the wave color can be selectable accordingto the environment. LCD brightness can be manually set. Continueworking over 8 hours with high performance lithium-ion batterymodule (with large capacity lithium-ion battery option), easy tobe dismantled and the battery module can be charged independentlyoffline. It is light and portable, easily to be taken by one hand;easy operation; superior reliability makes it longlife.
RANGE
0~ 6000mm(at steel velocity); range selectable in fixed steps orcontinuously variable.

RECEIVER
Real-time sampling at 160MHz high speed enough to record the defectinformation.
Rectification: Positive half wave, negativehalfwave, full wave, and RF
:
DBStep: 0dB, 0.1 dB, 2dB, 6dB step value as well as auto-gainmode
ALARM
Alarm with sound and light,.
MERMORY
Total 100 configurationchannels store all instrument operating parameters plus DAC/AVGcurve; stored configuration data can be easily previewed andrecalled for quick, repeatable instrument setup. Total 1000datasets store all instrument operating parameters plus A-scan. Allthe configuration channels and datasets can be transferred to PCvia USB port.
FUNCTIONS
Peak Hold:
Automatically searching thepeak wave inside the gate and hold it on the display.
Equivalent diametercalculation: find out the peak echo and calculate its equivalentdiameter.
Continuous Record: Record thedisplay continuously and save it to the memory inside theinstrument.
Defect Localization: Localizethe defect position, including the distance, the depth and itsplane projection distance.
Defect Sizing: calculate thedefect size
Defect evaluation: evaluate thedefect by echo envelope.
DAC: Distance AmplitudeCorrection
AVG: Distance Gain Size curvefunction
Crack measure: Measure andcalculate the crack depth
B-SCAN: Display thecross-section of the test block.
REAL-TIMECLOCK
Real time clock for tracking the time.
