Description:

Based on ultrasonic principle, digital ultrasonic flaw detector MFD550B can test, orient, evaluate and diagnose various flaws such as crack, lard, air hole in workpiece’s interior swiftly and accurately without any destruction. With full digital 640X480 TFT LCD display, it show the defect clearly under the dim light and strong sunlight environment. 0-9999mm measuring range can meet the requirement for general defect inspection in manufacturing industry, metallurgical industry, metal processing industry, chemical industry and so on. Low power design with large capacity and high performance lithium ion battery module,it can work more than 10 hours continuously. Full English master-slave menu, emphasizing on user experience, collecting shortcut keys, digital shuttle rotary wheel, cross menu three operating ways inone body, customers with different habits can operate it freely. With comprehensive performance self-checking function, it can automatically generate test reports and support for many languages. With high cost performance, it is the smart choice for the practical economic model of ultrasonic testing equipment.

Features:

Display

Hi-resolution (640×480 pixels) full digital TFT LCD with adjustable brightness, it is capable of providing high contrast viewing of the waveform from bright, direct sunlight to complete darkness.
The hi-resolution 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.

Pulse

Pulse Energy selectable among 200V, 300V, 400V, 500V
Pulse Width tunable from 30ns to 510ns to match the probes with different frequency
Pulse Repetition Frequency adjustable from 10 Hz to 1 KHz in 1 Hz increments
Damping selectable among 200Ω and 500Ω for optimum probe performance
Test Modes including Straight, Angle, Dual and Thru-transmission

Receiver
Sampling:10 digits AD Converter at the sampling speed of 400 MHz
Rectification:Positive Halfwave, Negative Halfwave, Fullwave and RF
Analog Bandwidth: 0.2MHz to 20MHz 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 100 channel files to store calibration set-ups
Memory of 1000 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 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, 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 velocityFlaw 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. Sound-path, Surface Distance and Depth are directly displayed when using angle
probe.

    Both the DAC and the AVG method of amplitude evaluation are available. 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 waveform to live A-Scans to easily interpret test results.
