HAVER & BOECKER began producing woven wire cloth in Hohenlimburg, Germany in 1887. Today, the company is one of the world’s leading wire weaving companies with a global network of branches and manufacturing facilities. Sietronics proudly represents but a small portion of this company in Australia focusing on particle sizing and counting equipment. For additional details have a look at the official website www.haverboecker.com

Two companies, HAVER & BOECKER Germany and W.S. Tyler USA, have significantly shaped the developments in the field of test sieves and test sieve shakers during the past decades. They continue to play an important part in the international standardization of test sieves. They have also been working intensively on the development of appliances for dynamic image analysis for particle analysis for several years. One of the more recent developments in this area is the range of Photo-Optical Particle Size Analysis systems commercially known as the HAVER-CPA range

The HAVER-CPA measuring system is protected by national and international patents: DBP-No. DE 41 19 240 C2, EP-No. 0 518 188 B1, US Patent 5,309,215 and other foreign patents.

Thanks to the HAVER & BOECKER REAL TIME function, it can also be used as particle counting device. This new technology guaranties that all particles are detected and analyzed. The common ‘double-count’ caused by overlapping matrix-pictures in other systems are eliminated using this new technology. Faulty analysis due to undersize particles is also excluded. The digital CCD Line Camera calculates the equivalent of more than 24 mega pixels of a matrix camera. It can generate very large pictures of 128 mega pixels and more.

The HAVER CPA analyzes and calculates up to 10,000 particles per second. The particle size and shape calculations are performed pixel by pixel, independent of the angle of the particle. The unit can store each single particle, with all particle shape values. This single particle storage enables an almost infinite grading of the size classes. All particles can be stored as TIF image files for further analysis. The hardware offers a pixel size of 10 µm and guarantees an extremely high resolution even with ultra-fine particle mixtures.

HAVER CPA uses an internal bus control that allows connection to any professional bus network. All CPA units can be integrated into an online process without any additional alteration

The technology is nearly maintenance free, durable and developed for online use. It has been successfully used with many different materials and is established for use as a laboratory or online unit in industrial areas such as pharmaceutical, food, coal, quarries, mineral processing, crusher control, plastic, abrasives, dust particle analysis and many others. Measuring ranges can be adapted to suit specific applications from 0.022 - 30mm for the Haver CPA 3-2 to 200mm for the Haver-CPA Gravi OPT models.
