ECHOGRAPH 1095 – From Karl Deutsch of Germany
High-tech meets comfort: Ultrasonic Testing made simple
The new digital ultrasonic ECHOGRAPH 1095 now features time corrected gain (TCG) and back wall echo attenuation (BEA). The time corrected gain raises the gain with the ultrasonic sound path. Back wall echo attenuation uses a separate gain for measurements within a third monitor, thus making it possible to display the full back wall echo in an A-scan and thus take it into account for inspections even at high gain.
The extended memory functions can be flexibly used for corrosion testing (matrix memory), measurement series and individual measurements. All kinds of data, e.g. screenshots in BMP format or measurement series in CSV format, are stored on an 8 GB SD memory card for convenient data export. Connected to a PC via USB cable the ECHOGRAPH 1095 acts as an external drive. All pictures and data files can easily be opened within standard office software or within the KARL DEUTSCH software “eCom 95 pro” on the desktop.
To facilitate testing under difficult conditions, all 3 monitors can still be moved while the rest of the screen is frozen. Therefore data analysis and recording have the flexibility to be adjusted to the requirements after the actual measurement. This even works with amplitude evaluation methods, such as DAC, DGS, AWS and JIS. For most convenient handling and readability the new testing device features a large 7”-TFT colour display with an 800 x 480 pixel resolution.
A further innovation is the continuously adjustable 320 V square wave pulsar. The pulse width is automatically adjusted to the probe frequency when the probe parameters are loaded.
The User Friendly neck strap and case allows hands free operation and safety restraint for the Echograph

There are applications requiring the knowledge of cast iron nodularity, or its deviation from a reference value.
The nodularity is defined as the relation between the nodular graphite and the total graphite content. This value affects the cast iron properties to a great extent. A nodularity value of 100% signifies that the total graphite content exists as nodular graphite. The nodularity value controls the elastic properties and the tensile strength of cast iron. In general, the strength increases if the nodularity value increases as well.
A typical example for the utilization of nodular cast iron (abbreviation SGCI) is the well-known Castor container for the transport and storage of radioactive materials.
Ultrasonic testing offers the possibility to determine the material quality non-destructively by measuring the sound velocity.
In each case, the sound velocities are different for iron casting, nodular casting and casting with lamellar graphite. Thus, the determination of sound velocity turns out to be a fair method
to determine the nodularity.
However, the sound velocity does not only depend on the percentage of the nodular graphite but also on the alloy composition, the total graphite content, the manufacturing process and the grain structure.
To achieve a reliable statement on the value of nodularity, ideally the KARL DEUTSCH instrument ECHOMETER 1076 can be utilized since it is designed to measure wall thickness and sound velocity.
First of all the nominal value needs to be determined by means of a reference block, made from the same material as the material under test with identical material properties.
For the determination of the sound velocity the thickness of the object must be known as precisely as possible. For this purpose a digital calliper can be used which provides an interface for direct transfer of the thickness data to the gauge.
Areas of parts where a correct nodularity is essential need to be examined with special care. Upper and lower tolerance values can be adjusted with the ECHOMETER, thus enabling a comfortable, reliable and fast tracing of the quality. The tolerance range either may be defined empirically or by measuring the sound velocity of casted samples with defined maximum and minimum properties.
