MFD500B Ultrasonic Flaw Detector 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..
Display Hi-resolution (320×240 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. suitable for use on large work pieces and in high-resolution measurements. Pulser Pulse Energy selectable among Low, Medium and High. 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 100,200 and 400 for optimum probe performance Test Modes include Pulse echo, dual and thru-transmission Receiver Sampling10 digit AD Converter at the sampling speed of 160 MHz RectificationPositive 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. Gain0 dB to 110 dB adjustable in selectable steps 0.1 dB, 2 dB, 6 dB, and locked.
Gates 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.
Functions Semiautomatic two point calibration: Automated calibration of transducer zero offset and/or material velocity Flaw LocatingLive 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. Curved Surface Correction feature Crack Height Measure function Weld figure feature Magnify gatespreading 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 FreezeDisplay freeze holds waveform and sound path data B Scan display feature
Real Time Clock
The instrument clock keeps running tracking the time.
Communication High speed USB2.0 port. 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.
