Portable Ultrasonic Flaw Detector

Model Number: MFD500B Brand Name: TLead Key Specifications/Special Features: Pulse width tunable from 0.1 to 0.5S to match the probes with different frequencyPulse repetition frequency adjustable from 10Hz to 1kHz in 1Hz incrementsDamping selectable among 100Ω/200Ω and 400Ω for optimum probePerformance: test modes include pulse echo, dual and thru-transmissionReceiver:Sampling: 10 digit AD converter at the sampling speed of 160MHzRectification: positive half wave, negative half wave, full wave and RFAnalog bandwidth: 0.5MHz to 15MHz capability with selectable frequency ranges (automatically set by the instrument) to match probe for optimumPerformance:Gain: 0dB to 110dB adjustable in selectable steps 0.1dB, 2dB, 6dB and lockedGates:Gate start: variable over entire displayed rangeGate width: variable from gate start to end of displayed range
Gate height: variable from 0 to 99% full screen height
Alarms: threshold positive/negative
Memory: memory of 100 channel files to store calibration set-up
Memory of 1,000 wave files to store A-Scan patterns and instrument settings
All the files can be stored, recalled and cleared
Functions:
Semi-automatic two point calibration: automated calibration of transducer zero offset and/or material velocity
Flaw locating: live display sound-path, projection (surface distance), depth, amplitude
Flaw sizing: automatic flaw sizing using AVG/AVG or DAC, speeds reporting of defect acceptance or rejection
Digital readout and trig function: thickness/depth can be displayed in digital readout when using a normal probe and peam path, surface distance and depth are directly displayed when angle probe is in use
Both the DAC and the AVG method of amplitude evaluation are available
Curved surface correction feature
Crack height measure function
Weld figure feature:
Magnify gate: spreading of the gate range over the entire screen width video recording and play auto-gain function
Envelope: simultaneous display of live A-scan at 60 Hz update rate and envelope of A-scan display
Peak hold: compare frozen peak waveforms to live A-Scans to easily interpret test results
A scan freeze: display freeze holds waveform and sound path data B Scan display feature
Real time clock:
The instrument clock keeps running tracking the time
Communication:
High speed USB2.0 port
The optional DataPro software helps manage and format stored inspection data for high-speed transfer to the PC
Data can be printed or easily copied and pasted into word processing files and spreadsheets for further reporting needs
New features include live screen capture mode and database tracking
Battery: internal rechargeable Li-ion battery pack rated 7.2V at 8,800mAh, 8 hours nominal operating time depending on display brightness 8-10 hours typical recharge time knob
