EINSTEIN-II DGS - Salient Features

  • Built-in DGS/AVG curves for time proven flaw size evaluation
  • It has TCG (Time Controlled Gain) which compensates for amplitude decay with distance
  • Dynamic DAC curves which allow change of Test Range and Gain after plotting them
  • Built-in software for evaluation as per AWS standard

Rejection 0 to 100% FSH with LED indicator.
Rectification Full-wave rectified with filtering.
Frequency Broad Band amplifier 0.5 MHz to 15 MHz.
Test Modes Pulse echo and transmit/receive.
Transmitter Transmission pulse Negative spike with selectable high or low power.
Damping Damping high / low is selectable.
Freeze/Peak Freeze A- Scan Freeze and Peak Freeze available. In Peak freeze it holds echo dynamic pattern which is useful during angle beam probing to locate peak signal.

Monitor Dual gate adjustable in 1% of Screen width with Positive/Negative logic, Gate Expand modes.
Gate Expand Expands Range to width of the gate.
A-Scan memory 200 Trace Patterns can be stored (with Note/Detail) recalled, printed or transferred to PC via RS-232 serial port.
Calibration Set-up 50 different calibration set-ups can be Stored and Recalled.
Software EinSoft DGS Interface software for transferring A-Scan from Einstein-II DGS to PC is supplied.
Printer Attachment IBM compatible Printer having serial port can be directly attached to main unit for printing of stored A-Scan waveform with calibration data.
Display High brightness Colour LCD/TFT Display. Display area 320×240 pixel(122x92mm). Eleven different color scheme option.
Full Screen By pressing Zoom keyA-Scan can be displayed in Full Screen area.
ReferenceA-Scan Reference A-Scan pattern of standard test object can saved and recalled in the background for easy comparision during testing.
DAC Dynamic DAC curve can be Digitally plotted on screen with -6dB and -14dB DAC curves. DAC curve can be set as flaw monitor gate. Using minimum 2 to maximum 10 points DAC curve can be plotted.
DGS Defect size evaluation can be performed using 18 predefined probe settings and custom probe set-ups. Defect size is directly displayed in ERS value (Equivalent Reflector Size).
Digital Readout Thickness/Depth can be displayed in digital readout when using a normal probe and Sound path, Surface Distance and Depth are directly displayed when angle probe is in use. Measurement point can be selected to be Peak or Flank. Echo height, ERS value, dB diff of DGS curve to signle height, Echo height w.r.t. DAC can be measured.
Measurement Unit Metric or British unit of measurement is selectable.
Video Output Composite video signal (PAL) output for connection to a TV.
PRF High or low PRF is selectable.
