Ultrasonic Flaw Detector (MFD800B)
|
Ultrasonic Flaw Detector (MFD800B) 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 incorporates many advanced signal processing features including a 15MHz RF bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable square wave pulser to optimize penetration on thick or highly attenuating materials. The instrument can be widely used in locating and sizing hidden cracks, voids, disbands, and similar discontinuities in welds, for gings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components. 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. TVG(Time Varied Gain). AWS D1.1. 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.
