The greater the impedance ratio the more sound energy will be reflected. A short burst of Ultrasound is introduced into test material so some or all of the energy is reflected by discontinuities. light in weight and user friendly Digital Ultrasonic Flaw Detector. compact. High frequency sound (Ultrasonic sound) waves are introduced into the test material/part from a transducer/probe that is usually coupled to the test piece by water or other suitable coupling liquid.MODSONIC 1 Introducing Einstein-II DGS Einstein-II DGS is a portable. 1. porosity and other discontinuities that could affect the performance of material and components. Fully charged battery gives continuous working of eight hours and charging time is just 5 to 6 hours. requiring access from only one side of the test piece. It can also be used for thickness gauging of homogeneous material. Einstein-II DGS --1-MODSONIC 2 How does an Ultrasonic Flaw detector Work Einstein-II DGS is a single channel Ultrasonic-testing instrument used for the inspection of homogeneous material for the presence of inclusions. it provides wide viewing angle and allows fast scanning speed. It shows the ultrasonic energy generated in the test piece and resultant instrument display. Einstein-II DGS has COLOR LCD display. The reflection of the ultrasound energy is a function of the ratio between the acoustic impedance of the discontinuity and the base material. 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. The transducer converts electric signals to Ultrasound and vice versa. The principle of Ultrasonic testing is shown in fig. The reason for this is its ability to position the transducer/probe away from the weld bead yet propagate energy into the weld zone. TR probe is suitable for the thickness gauging of pitting and corrosion and also for better surface resolution. Another reason to use angle beam testing on the welds is to position the sound beam more normal to the expected discontinuities since the flaws in welds are usually perpendicular to the test piece (except porosity). In most angle beam probes. Einstein-II DGS --4-- . Normal beam probe is used mostly for flaw detection and thickness gauging (refer figure 1.MODSONIC measurement. through a material under test.) 2> TR probe: This probe contains separate transmitting and receiving elements as showing in figure 2 usually mounted on delay lines. 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 Probe 1> Straight beam Probe: This probe introduces ultrasound normal to the test piece surface utilizing longitudinal or compression waves. This probe is suitable for inspection of the welds. Einstein-II DGS --3-- MODSONIC 3> Angle Beam Probe: This probe introduces ultrasound at an angle to the surface of the test piece. This design improves near surface resolution by separating the initial pulse from the received echoes. Figure 3 shows the principle of angled beam weld testing. This principle utilizes the precise timing of the transit time of a short burst of ultrasound energy. the wave energy is mode converted from a longitudinal wave to a shear wave by the refraction principle. 12 and 20 dB Step sequence.
