MITECH Ultrasonic Digital Flaw Detector (MFD620C)

Overview

The MFD620C 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 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 6000 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 digit AD 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, 1.0dB, 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 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. As long as 2 hours movie can be saved to the inside memory. It 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.

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.
