Einstein-II DGS

1 Introducing Einstein-II DGSEinstein-II DGS is a portable, compact, light in weight and user friendly Digital

Ultrasonic Flaw Detector. Einstein-II DGS has COLOR LCD display, it provides wideviewing angle and allows fast scanning speed. Fully charged battery gives continuous

working of eight hours and charging time is just 5 to 6 hours. Trace pattern can be

directly printed out on conventional PC printer having serial port for interface or can be

transferred to PC via RS232 Serial port for storage of data.

2 How does an Ultrasonic Flaw detector Work

Einstein-II DGS is a single channel Ultrasonic-testing instrument used for the inspectionof homogeneous material for the presence of inclusions, porosity and other

discontinuities that could affect the performance of material and components. It can also

be used for thickness gauging of homogeneous material, requiring access from only one

side of the test piece. High frequency sound (Ultrasonic sound) waves are introduced intothe test material/part from a transducer/probe that is usually coupled to the test piece by

water or other suitable coupling liquid. The transducer converts electric signals to

Ultrasound and vice versa. A short burst of Ultrasound is introduced into test material sosome or all of the energy is reflected by

discontinuities. The reflection of the ultrasoundenergy is a function of the ratio between the

acoustic impedance of the discontinuity and thebase material. The greater the impedance ratiothe more sound energy will be reflected. The

principle of Ultrasonic testing is shown in fig. 1.

It shows the ultrasonic energy generated in thetest piece and resultant instrument display.

measurement. This principle utilizes the precise timing of the transit time of a short burst ofultrasound energy, through a material under test. The ultrasound waves travel to the far side of the

test piece and reflect back to the transducer/probe and a measurement is obtained.

Basically three typed of transducers/probes are available for different types of applications:

1> Straight beam Probe (Normal probe)

2> TR probe (Dual crystal probe)

3> Angle beam Probe1> Straight beam Probe:This probe introduces ultrasound normal to the test piece surface

utilizing longitudinal or compression waves. Normal beam probe is used mostly for flaw

detection and thickness gauging(refer figure 1.)

2> TR probe: This probe contains separate transmitting

and receiving elements as showing in figure 2

usually mounted on delay lines. This designimproves near surface resolution by separating

the initial pulse from the received echoes. TR

probe is suitable for the thickness gauging of pitting

and corrosion and also for better surface resolution.

3> Angle Beam Probe:This probe introduces ultrasound at an angle to the surface of the testpiece. In most angle beam probes,

the wave energy is mode converted from a

longitudinal wave to a shear wave by therefraction principle. This probe is suitable for

inspection of the welds. The reason for this is

its ability to position the transducer/probeaway from the weld bead yet propagate energy

into the weld zone. Another reason to use angle

beam testing on the welds is to position thesound beam more normal to the expected discontinuities since the flaws in welds are usually

perpendicular to the test piece (except porosity). Figure 3 shows the principle of angled beamweld testing.

5 Setting of timeKeep key 1 press and switch ON Einstein-II DGS. After displayof menu Parameter, release key 1 and again press key 1 so Time setting menu will be

displayed. Now set required Time/Data by pressing

UP/DN parameter key. Then press key 2 for to

store/set current time to value set as per display.Press key 3 to exit without store/set current time.

Factory Default Calibration set-upIn Einstein-II DGS last calibration set-up remain

store So when further Einstein-II DGS Starts itwill start with last setting, But due to some reason

if stored calibration is corrupted then it will startswith factory default calibration set-up. If any userwant to recall factory default calibration set-up

then press key 4, keep it press and Switch on

Einstein-II DGS. After displaying menu parameter

release key 4.

6 Interface of PrinterEinstein-II DGS has direct printout facility of A-Scan pattern with full calibration set-up values.

It can be printed out on conventional PC printer having a Serial Communication connector. So

computer or special printer is not required. Printer should be IBM-PC compatible with serial

port. Serial port setting is as below. Serial printer EPSON FX/LQ type recommended. (To setbelow setting in serial printer refer operating manual supplied with the printer).

Baud Rate 9600 Parity bit NoneData Bits 8 Stop Bits 1

To print out trace pattern, follow the below given steps.

> Connect Serial cable (supplied with Einstein-II DGS) between connector (19) of

Einstein-II DGS and serial printer.> Switch ON Serial PC printer.

> Switch ON Einstein-II DGS.

> Get the required Trace pattern and freeze using Freeze key (3).> Using Menu key go to memory menu (4).

> Using ACTION UP/DN key select PRINT.

> Press ENTER UP/DN key to initiate printing.

For Interface with PC Using Serial port Refer Help.txt file supplied in SoftwareCD.

Einstein-II DGS

7 Power Supply

Einstein-II DGS is powered by a Lithium-Ion battery pack ATB1, which is fitted in Einstein-II

DGS using two screws. It electrically connects to Einstein-II DGS via two internal terminal

contact points. With fully charged battery pack ATB 1, Einstein-II DGS can operatecontinuously for eight hours, under typical operating conditions. The battery pack ATB 1 can be

charged when inside Einstein-II DGS by connecting Battery charger ATC 1 to the connector

(18). Alternatively, the battery pack ATB 1 can be charged outside Einstein-II DGS whichallows uninterrupted use of Einstein-II DGS using multiple battery packs.

Battery Charging

The battery Charger ATC 1 supplied with Einstein-II DGS is a special quick- charge charger.

The charging time is just 5 to 6 hours. ATC 1 battery charger is suitable for use with mains

supply from 100 to 240 volts AC/50 Hz. The LED on charger illuminates to indicate power on.When the battery voltage is low (discharge condition) the LED glows RED. When the battery is

almost charged the LED turns to yellow. When the battery is full charged the LED glows green.

The output voltage from the charger is 16.4 Volts DC. The charging current is constant at 2.0Amps.

8 Precaution

> Avoid shock to the Einstein-II DGS and probes.

> Wipe the couplant off the probe and Einstein-II DGS after use.

> When battery pack is out-of Einstein-II DGS, keep battery contacts away from

metal object

> Never heat the battery pack ATB 1 nor throw into a fire.
