Overview
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.
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 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
² Pulse

Positive Halfwave, Negative Halfwave, Fullwave and RF
² Analog
Bandwidth: 0.5MHz to *5MHz capability with selectable frequency
ranges (automatically set by the instrument) to match probe for
optimum performance.
² Gain:
0 dB to **0 dB adjustable in selectable steps 0.1 dB, 2 dB, 6 dB,
and locked.
Gates
² Two
fully independent gates offer a range of measurement options for
signal height or distance using peak triggering.
² The
echo-to-echo mode allows accurate gate positioning for signals
which are extremely close together.
² Gate
Start: Variable over entire displayed range
² Gate
Width: Variable from Gate Start to end of displayed range
² Gate
Height: Variable from 0 to *9% Full Screen Height
² Alarms:
Threshold positive/negative
Memory
² Memory
of ***0 channel files to store calibration set-ups
² Memory
of ****0 wave files to store A-Scan patterns and instrument
settings.
² All
the files can be stored, recalled and cleared.
Video Recorder
² 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.
² Video
Recorder is useful in many situations, it is very convenient for
those who want to analyze the probing activities later.
