Description

MFD**0B Ultrasonic Flaw Detector OVERVIEW Display Hi-resolution (**0×**0 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 *0 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 ***9 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 *0 Hz to 1 KHz in 1 Hz increments. Damping selectable among **0Ω、**0Ω and **0Ω for optimum probe performance Test Modes include Pulse echo, dual and thru-transmission Receiver Samplingï&frac*4;š*0 digit AD Converter at the sampling speed of **0 MHz Rectificationï&frac*4;šPositive Halfwave, Negative Halfwave, Fullwave and RF Analog Bandwidth: 0.5MHz to *5MHz capability with selectable frequency ranges (automatically set by the instrument) to match probe for optimum performance. Gainï&frac*4;š0 dB to **0 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 *9% Full Screen Height Alarms: Threshold positive/negative Memory Memory of **0 channel files to store calibration set-ups Memory of ***0 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 Locatingï&frac*4;šLive display Sound-path, Projection (surface distance), Depth, Amplitude,
