Echograph 1095

The Echograph 1095 features time corrected gain and backwall echo attenuation.

Designed as an ideal instrument for manual ultrasonic testing, it is equipped with the advantages of digital test equipment: Sturdy mechanical and electronic components with a large, high-contrast screen and a convenient, practical user interface make it nearly indestructible even in harsh operating environments or outdoors.

Main features:

The powerful ultrasonic flaw detector features 3 monitors for amplitude and time-of-flight measurement and 3 associated status lamps on the front panel for monitoring of threshold levels. The very compact instrument (54 mm case depth) provides fast digital ultrasonic electronics with a high sampling rate and pulse repetition frequencies up to 5000 Hz.

Operating assistance for less-experienced users

A convenient user guidance supports less-trained UT inspectors, also during probe handling and instrument adjustment: Simply activate the wizard and follow the instructions on the screen. Even difficult evaluation procedures for defect sizing (DAC/TCG, JIS, AWS or DGS) are set almost automatically.

Display Evaluation with DGS and DAC

Display evaluation DGS method (option):

• Not restricted to special probes (DGS curve is calculated within the instrument)
• Visualisation of the reference DGS curve
• Defect size (FBH = flat bottom hole) is directly shown
• DGS with KARL DEUTSCH TR probes
• Indication of up to 6 additional threshold curves

Display evaluation DAC method (option):

• Reference line method (EN 1330-4)
• Optical and acoustical alarm when exceeding or dropping below the curve
• Indication of up to 6 threshold curves
• DAC support points can be manually added, shifted and deleted (up to 16 points)
• Calculation of time corrected gain from the DAC curve

Time Corrective Gain TCG

For TCG evaluation the gain is adjusted depth-dependent according to the previously recorded DAC curve (option).

As a result, large reflectors with equal sizes are displayed with equal amplitudes though they are located in different depths.

Backwall Echo Attenuation

Very often the flaw echoes between transmitter pulse and backwall echo are much smaller than a backwall echo used for monitoring of coupling. With activated backwall echo attenuation monitor 3 can be shifted over the backwall echo and a separate gain can be selected there. As a result, it is possible to show all interesting echoes in a useful height (in the example picture: amplification 28 dB within and 45 dB outside of monitor 3.

The high-precision distance measurement is executed with the aid of signal zero crossings and uses the RF-mode of the unit. Exclusively considering zero crossings minimizes influences of amplification and signal shape, thus wall thickness values are highly accurate and stable. Besides arithmetic averaging, storing of minimal and maximal values is available. As a result, the unit is optimized e.g. for the measurement of corrosion.
