MITECH Ultrasonic Flaw Detector MFD350B

MITECH Ultrasonic Flaw Detector MFD350B 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 6000 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 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 : 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 10MHz 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. 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. 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 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. Battery Internal rechargeable Li-ion battery pack rated 7.2V at 8800 mAh 8 hours nominal operating time depending on display brightness 8-10 hours typical recharge time Knob Operating adjustments are easily and quickly made using the rotary knob.
