TOFD Ultrasonic Flaw Detector

Features:

1. General Features:

With high light TFT screen, the background color and brightness can be adjusted according to environment; make it clearly displayed under high-light or low-light environment.
It tested with ultrasonic diffraction signal, solve the limitation and insoluble of convention ultrasonic testing which only use A-scan
Intergraded with A scan, B scan, C scan, CB scan, P scan, TOFD imaging and guided wave imaging
With Synthetic Aperture Focusing Technique (SAFT), improve defect measurement accuracy
With stable waveform, high SNR (Signal to noise ration), identify the defects more clearly
With built-in detection process standards, and the instrument can help user automatically generate detection process
Using a scanner instead of holding probe with hand, more quickly, more steady and more accurate
TOFD testing with multi-channels, cover all area of weld saw
The A scan waveform of each point position can be recorded
Built-in probe position encoder
With large storage space and the testing data can be transmitted through the network
The instrument shell is made by polymer composites, shockproof and drop resistance
Integrated data cable with low transmission loss
Designed according to EN12668-1：2000 standard, with Chinese and English certificate

1.  Flaw Detector features:

Scanning mode: non-parallel and parallel scan for weld
Defect location: analysis software directly read out the defect location, depth and its height
Defects display: Visual display the location of the defect in the workpiece and the vertical endpoint
A-scan: RF A-scan waveform improve evaluation capacity of defect signal
B-scan: demonstrate the cross section with defects
TOFD imaging: display the weld saw section with scan dimension and depth dimension, the location, length, depth and height of defects will be demonstrated

1. Testing scope

Zoned coverage of 200mm thickness with multi-channel TOFD and PE testing, can be extended to cover 400mm thickness

1. Data analysis

Through Wave Removal: special tool to process near-surface defect, improve near-surface defect analysis accuracy
Horizontal and Vertical Shift: Meet different operation habit
SAFT: Effectively improved the defect measurement accuracy 

1. Data record and output

Testing parameters can be preset, loaded, saved, edited, printed and sent to PC easily.
One-time 40m TOFD scan reach large data record storage
The testing data, image can be auto named and auto-saved.
The testing data, image can be can be saved, loaded, analyzed, printed and send to PC easily
With USB2.0 , LAN and VGA communication interfaces

1. Off-line analysis software function
