FoamDDI – Automated ASTM D892 and D6082 Foam Test Unit

FoamDDI automatic D892 and D6082 foam test unit accurately controls the airflow, temperature and sequence, which is then augmented using a unique VISION algorithm to accurately determine the height of static and dynamic foam heights, improving the precision and accuracy of ASTM D892.

Foam Digital Detection Imaging

Full automation of D892 and D6082 foam test and Elimination of User Bias.

Contamination in the form of air which can be foam or the entrained air bubbles creates adverse effects in machinery and lubricants. Issues such as incomplete oil films, low oil pressures, accelerated oil degradation, and additive depletion are symptoms of high foam tendency, which can produce metal wear, inadequate lubrication, cavitation in pumping, and mechanical failures.

Standard Test Method ASTM D892 was developed for lubrication testing and to determine the foaming characteristics of lubricant oils by empirically rating their foaming tendency and stability. Standard Test Method ASTM D892 was developed to determine a lubricant’s ability to resist foam formation and dissipate foam creation. However, measuring foam heights is a challenge, as it relies on the human eye” to measure foam heights which creates a significant user resulting in human errors, bias, and poor repeatability and reproducibility. The FOAM Digital Detection Imaging (FoamDDI) accurately controls the airflow, temperature, and sequence, which is then augmented using a unique VISION algorithm to accurately determine the station’s height and dynamic foam heights, while greatly improving the precision and accuracy.

Principle:

The all-new FoamDDI eliminates the need for sample manipulation and critical timing involved with regular foam detector methods. Using a patent-pending heating and cooling system with a vision algorithm and lubrication testing automation the FoamDDI, records, calculates, and displays accurate results with little to no operation bias. Determinations come from this foam detector in minutes!

• Using a high-resolution camera with state-of-the-art optics for lubrication testing, FoamDDI quickly brings a sample in the inserted cylinder to test temperature.
• After soaking, the foam detector and analyzer start air for FOAM production.
• Air Flow is controlled using Mass Air Flow Controllers (MFC)
• At the 5 min. mark, an LED light source is activated.
• The VISION algorithm is activated and begins analysis
• The complete sequence is recorded and analyzed.
• The test is completed or if desired, the next sequence can automatically continue.
