TIDAS is a bench-top system that automates the traditional grind-o-meter test, providing in-depth particle data and an objective, repeatable reading every time.
Features
A revolution for particle size analysis due to its robust, low-maintenance design, super-sharp imaging, customizability and versatility
Fineness of grind is determined objectively, using an integrated camera and a darkfield illumination technique to capture the result.
Automates the analysis of a wide range of samples using a Hegman gauge. (A traditional Hegman test is entirely subjective and prone to human variance - from the drawdown application itself, to lighting conditions, eyesight health and simple human judgement. TIDAS can be used to determine the exact production time required to grind raw ingredients down to the optimum particle size.)
Each reading with TIDAS takes less than 20 seconds and will reproduce the exact same reading for the same dispersion, every time.
The analysis process uses an intuitive algorithm and precise photo capture techniques to ensure the readings are stable and reliable.
The system integrates a high-definition line scan camera, which contributes to the generation of distortion-free images. Every capture is digitally stored.
TIDAS incorporates an array of diverse technologies to automate both the drawdown and the reading of the Hegman gauge, accurately determining grind quality.
The dark field illumination technique is used to capture the image of the dispersion on the Hegman gauge. This works by shining a beam of light at a low angle onto the gauge, and the scattered light (caused by the uneven surface of the particles) is eliminated from the image, essentially providing a perfect negative photo. This provides a precise and detailed capture of the particle sizes and quantities which is then analyzed by a customized algorithm.
Integral to the operational mechanics, are encoded stepper motors that propel both the gauge and blade axes. These motors are orchestrated by purpose-built motor drivers, facilitating precise and replicable movements for both the gauge and blade components.
TIDAS is compatible with paints, inks, resins, adhesives, clear and metallic materials, battery materials, foods, cosmetics and much more.
The TIDAS software is designed to identify and eliminate dust, bubbles and foaming from the dispersion. It can also robustly take readings from clear and metallic liquids, notoriously difficult to rate by eye. As well as an overall rating, the software can be configured to report various data, including the number of particles within set areas, or even per micron slice. It is distinguished by its wealth of features and high degree of configurability. This software package empowers users with a versatile toolkit for tailored operation and analysis. The raw image captured is presented alongside the digital analysis, and the micron count. The count identifies the exact number of particles per micron slice, which provides a defined and repeatable rating. Data for every drawdown is automatically stored and can be exported for deeper analysis if required. Users are able to preset TIDAS to automatically produce a pass or fail against their quality standards. Each drawdown takes around 20 seconds to produce the result.
