Leakages are the Achilles heel of all compressed air and gas networks. According to various studies, Leak detection and the sealing of Leakages can save an average of around 30% of compressed air costs. Regular inspection and consistent elimination are therefore essential. Under certain conditions, the initial investment in Leakage measuring devices is also subsidised by BAFA (further information can be found in our news section).

At room temperature, both ceramics and glasses will undergo fast fracture in a tensile test before any plastic deformation has occurred. Fast fracture is where the specimen breaks by the rapid initiation, growth and failure of a crack.

UNSW is located on the unceded territory of the Bidjigal (Kensington campus), Gadigal (City and Paddington Campuses) and Ngunnawal peoples (UNSW Canberra) who are the Traditional Owners of the lands where each campus of UNSW is situated.

The elastic modulus (Young's Modulus) of ceramics is usually higher than for metals, because ceramics are bonded either covalently or ionically. This bonding is stronger than metallic bonding. Glasses have a lower modulus than other ceramics due to their non-uniform (amorphous) atomic structure.

Ceramics are typically hard and brittle. While their strength in compression is very high, they are not suitable for loading in tension. Their brittle qualities mean that they fracture very easily. In compression, a crack is not easily propagated, but in tension the crack is free to grow.

Importanceof ceramic materials

Around 10% of total industrial electricity consumption is used for compressed air generation in industrialized countries, and in Germany the figure is as high as 14%. Leakages are the main factor for energy losses and most compressed air systems show losses in the range of about 20 % to 40 %, in bad systems even more than 60%. Fixing compressed air leaks is the most effective action for reducing the energy consumption. Compressed air leaks often waste energy 8760 hours (24 h x 365 d) a year and increase compressor run times, which also shortens maintenance intervals. Therefore, it is a must to detect and eliminate leakages frequently. Our LD-Series will give you all the function needed to detect leakages and measure the consequences in terms of energy consumption and wasted money.

Physical propertiesof ceramic materials

Typical applications of our measuring instruments in this section are leakage detection in compressed air systems and leak testing of unpressurized systems.

Ceramics have a fracture toughness about fifty times less than metals, even though their bonding forces are higher. Because of their susceptibility to cracking, consideration of the strength of ceramics requires consideration of their cracking behaviour. This quite often involves design and analysis with the use of fracture mechanics.

It is because of the inherently low fracture toughness of most ceramics that they are usually loaded in compression. Ceramics have compressive strengths about ten times higher than their tensile strengths.

While the LD450 Leak detector already locates Leakages very reliably, our LD500 can also calculate the effects of these Leakages, giving the user the greatest possible transparency regarding potential cost savings. If you are not sure which Leak detection device is the right choice for your application, contact our experts. We will be happy to help you find the right device.

Usesof ceramic materials

Ceramics and glasses are the hardest known materials. Many ceramics are often used as abrasives for this reason. They are hard because of their ordered structure, it is very difficult for dislocations to move through the atomic lattice.

Our Leakage measuring devices are typically used, for example, for Leak detection in Compressedair systems or as part of leak testing of unpressurised systems. The principle of the detection devices is based on ultrasonic leak detection. Our LD devices convert the inaudible ultrasonic waves generated by Compressed air leaks into audible sound, making them very easy for the user to localise.

Ceramics are particularly susceptible to cracking because they usually contain many inherent small flaws or cracks. The tensile strength of a ceramic is determined by the length of the longest flaw.
