Exhibitor Profile

Floor Plan

Sievecal is a fully automated instrument designed to provide pass fail compliance data for laboratory test sieves. With an average analysis time of two minutes, sieves are quickly and accurately verified for compliance to ASTM, DIN, or ISO standards.

PRINCIPLE

Based on image analysis measurement technique, Sievecal provides an entire scan of the sieves surface following a computer controlled standard operating procedure. Using sophisticated digital imaging hardware, and a robust software package, a pre-defined standard operating procedure makes testing sieves as easy as a click of a mouse.

As the sieve rotates, the entire surface of the mesh is analyzed, providing real time information on wire thickness, and aperture dimensions. A full report is generated for each sieve, and can be printed, or saved as a file.

Operator can define the minimum numbers of images (surface) or the minimum numbers of holes.
Operator can define the holes detection parameters.
Real time sieve opening measurement and sieve opening Idcard.
Sieve opening scatter plot.
Sieve opening size distribution.
Single sieve opening visualization.

Particle shape and size analyzers based on image analysis technology

For powders, suspensions, fibers, emulsions, bacterias, viruses etc…

The company Occhio produces and offers you, since 2001, a wide range of instruments for wet and dry applications in particles size analysis and shape characterization (morphology).

Occhio offers a complete line of particle image analyzers. Particles may be dry materials dispersed in air or particles dispersed in fluids. Particles ranging in size from about 400 nanometers up to several centimeters may be measured. Using a unique optical design, these instruments produce high quality images which are processed using the robust algorithms developed by Occhio .

A team of engineers aiming to broaden your horizons
Occhio inherits a large experience in the fields of optoelectronics, computer assisted image analysis, geostatistics and raw materials characterisation. Thanks to a remarkably international and multidisciplinary team of engineers, Occhio is able to propose to her customers a complete range of solutions starting from product visualisation up to statistical process control. Be it for laboratory instrumentation, for “at line” or even “on line” imaging solutions, Occhio will be your privileged partner for high-level engineering.

The image revolution: seeing is measuring
Digital imaging has entered our ordinary lives. This doesn’t just mean a stream of millions of pixels! It is a real technological revolution bringing with her a whole new world of measurements that were simply inaccessible up to now.

Thanks to the flexibility of imaging technologies, the smallest as well as the largest particles, the most friable as well as the heaviest particles can all be turned into sets of pixels. But, the exceptional amount of optical information is such that only the most intelligent algorithms are able to accurately and efficiently exploit the data.

It’s precisely here, in the very heart of a pixel’s world, that the innovation brought to the market by Occhio is the most decisive
