1 Introduction The MFD**0C 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 *5MHz 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. 1.1 Features of the Instrument
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 MFD Series of instruments
remain.
Display
Hi-resolution (**0
×**0
pixels) multi-color TFT LCD with 4 user-selectable 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 *0 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 ***9 mm in steel; range selectable in fixed steps or
continuously variable. Suitable for use on large work pieces and in
high-resolution measurements.
Pulser
Pulse Energy selectable among **0V, **0V, **0V, **0V and **0V..
Pulse Width tunable from 0.1µs to 0.5 µs to match the probes with
different frequency.
Pulse Repetition Frequency adjustable from *0 Hz to 1 KHz in 1 Hz
increments.
Damping selectable among *8
Ωã€**0
Ωã€**0
Ω and **0
Ω for optimum probe performance
Test Modes include Pulse echo, dual and thru-transmission
Receiver
Sampling
:*0 digit AD
Converter at the sampling speed of **0 MHz
Rectification
:Positive
Halfwave, Negative Halfwave, Fullwave and RF
Analog Bandwidth: 0.5MHz to *5MHz capability with selectable
frequency ranges (automatically set by the instrument) to match
probe for optimum performance.
Gain
:0 dB to **0 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 *9% Full Screen Height
Alarms: Threshold positive/negative
Memory
Memory of ***0 channel files to store calibration set-ups
Memory of ****0 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 *0
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.
- 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 *0 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 and
U-BRIDGE. In U-DISK mode, the instrument acts as a usb flash disk
when connected to 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
