Introduction
The UD-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.
1.1Features 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 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 0.5µs to
match the probes with different frequency.
Pulse Repetition Frequency
adjustable from *0 Hz to 1 KHz in 1 Hz increments.
Damping
selectable among *8Ω、**0Ω、**0Ω and **0Ω 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
l Semiautomatic two point calibration: Automated
calibration of transducer zero offset and/or material
velocity
l Flaw Locating：Live
display Sound-path, Projection (surface distance), Depth,
Amplitude,
l Flaw sizing: Automatic flaw sizing using
