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
Energy selectable among **0V, **0V, **0V, **0V and **0V..
² Pulse
Width tunable from 0.1µs to 0.5µs to match the probes with
different frequency.
² Pulse
Repetition Frequency adjustable from *0Hz to 1KHz in 1Hz
increments.
² Damping
selectable among *8Ωã€**0Ωã€**0Ω and **0Ω for optimum probe
performance
² Test
Modes include Pulse echo, dual and thru-transmission
Receiver
² Sampling:
*0 digit AD Converter at the sampling speed of **0 MHz
² Rectification:
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.
