Certification of Test Sieves

"Certified" test sieves are standard production products, specifically reexamined for assurance to referenced specifications. The sieve is serialized and supplied with documentation, traceable to NIST, detailing the openings and wire diameters of the mesh. W. S. Tyler uses a View Bazic 8 Image Analyzing Machine to perform our "Certification" and "Recertification" services. This state of the art equipment is capable of measuring to tolerances of less than one micron.

In addition the View Bazic 8 allows W.S. Tyler to measure considerably more openings and wire diameters than currently specified by ASTM E-11. The added measurements and the pattern of examination offer statistically more valid information.

CPA Particle Analyser

A CPA can reduce the time and labor costs involved with traditional sieve analysis. Both the size and shape of your material is analyzed rapidly and accurately. The CPA is beneficial both as a stand-alone laboratory unit, or for in-line process control.

CPA technology provides the accuracy required to verify products are within specifications. That means eliminating the potential for product rejections altogether. Think about the positive effect that will have on you bottom line, and the ability to enhance the quality of the products your company is known for.

CPA stands for Computerized Particle Analyzer; a new generation replacement for traditional lab and sieve equipment. It uses a high resolution CCD (charge coupled device) camera and sophisticated software developed for particle size and shape analysis of dry, free-flowing, non-agglomerating particles in bulk materials. The 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. Featuring a real-time function, it can also be used as a particle counting device. The CPA is used to successfully analyze many different types of materials such as pharmaceuticals, food products, minerals, plastics, abrasives, etc.
