MITECH MFD800B Ultrasonic Flaw Detector

The MFD800B is an advanced digital ultrasonic flaw detector featuring a multi-color TFT LCD and a host of new features to meet challenging inspection requirements. It combines powerful flaw detection and measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its high-speed USB port. The instrument incorporates many advanced signal processing features including a 15MHz RF bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable square wave pulser to optimize penetration on thick or highly attenuating materials. The instrument can be widely used in locating and sizing hidden cracks, voids, disbands, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components.

OVERVIEW

The MFD800B is an advanced digital ultrasonic flaw detector featuring a multicolor TFT LCD and a host of
new features to meet challenging inspection requirements. It combines powerful flaw detection and
measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its high-speed USB port.
The instrument incorporates many advanced signal processing features including a 15MHz RF
bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in
high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable
square wave pulser to optimize penetration on thick or highly attenuating materials.
The instrument can be widely used in locating and sizing hidden cracks, voids, disbands, and
similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels,
turbines, and structural components.

KEY FEATURES
The instrument extends the performance and range of applications that are capable of being satisfied
by a portable instrument. The quality, portability, durability, and dependability that you have come to
expect from the popular Mitech MUT Series of instruments remain.

DISPLAY
Hi-resolution (640×480 pixels) multi-color TFT LCD with 4 userselectable brightness
control provides high contrast viewing of the waveform from bright, direct sunlight to complete darkness.
The hi-resolution multi color TFT LCD display with fast 60 Hz update gives an “analog look” to the
waveform providing detailed information that is critical in many applications including nuclear power
plant inspections.

RANGE
Up to 9999 mm in steel. suitable for use on large work pieces and in high-resolution measurements.

PULSER
Pulse Energy selectable among Low, Medium and High.
Pulse Width tunable from 0.1µs to 0.5 µs to match the probes with different frequency.
Pulse Repetition Frequency adjustable from 10 Hz to 1 KHz in 1 Hz increments.
Damping selectable among 100Ω、200Ω and 400Ω for optimum probe performance
Test Modes include Pulse echo, dual and thru-transmission

RECEIVER
Sampling:10 digit AD Converter at the sampling speed of 160 MHz
Rectification:Positive Halfwave, Negative Halfwave, Fullwave and RF
Analog Bandwidth: 0.5MHz to 15MHz capability with selectable frequency ranges (automatically
set by the instrument) to match probe for optimum performance.

Gain:0 dB to 110 dB adjustable in selectable steps 0.1 dB, 2 dB, 6 dB, and locked.

GATES
Two fully independent gates offer a range of measurement options for signal height or
distance using peak triggering.
The echo-to-echo mode allows accurate gate positioning for signals which are extremely close together.
Gate Start: Variable over entire displayed range
Gate 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 1000 channel files to store calibration set-ups
Memory of 10000 wave files to store A-Scan patterns and instrument settings.
All the files can be stored, recalled and cleared.

Video Recorder
Screen scenes can be captured as movie files.  More than 10 hours movie can be saved to
the inside memory.  They can be re-played using the instrument or the PC software delivered with the instrument.
Video Recorder is useful in many situations, it is very convenient for those who want to analyze
the probing activities later.

FUNCTIONS
Semiautomatic 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.
TVG(Time Varied Gain).
AWS D1.1.
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. Two USB modes can be selected: U-DISK na U-BRIDGE. In U-DISK mode,
the instrument acts as a usb flash disk when connected with pc. Configuration files, saved pictures
and recorded movies can be copied to pc when possible. In U-BRIDGE mode, the instrument
exchanges data with DataPro Software. 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 6600 mAh
8 hours nominal operating time depending on display brightness
8-10 hours typical recharge time

KNOB
Operating adjustments are easily and quickly made using the rotary knob.
