Product Details

MFD 800C Ultrasonic Flaw Detector

1 Introduction
The MFD800C 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.
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 (640×480 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 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; 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 200V, 300V, 400V, 500V and 600V..
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 68Ω,100Ω,150Ω and 500Ω for optimum probe performance
Test Modes include Pulse echo, dual and thru-transmission
Receiver
Sampling:10 digitAD 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 storeA-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.
