MFD800C Ultrasonic Flaw Detector

KEY FEATURES

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.

RANGE

Up to 9999 mm in steel; range selectable in fixed steps or continuously variable.

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

Memory

Memory of 1000 channel files to store calibration set-ups

Memory of 10000 wave files to store A-Scan patterns and instrument settings.

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.
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 60 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

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.
