FILTER DEBRIS ANALYSIS (FDA) The answer is in the filter Automated FDA is an effective, and easily-deployable method of assessing gear and rolling element bearing damage modes. It can be used as a stand-alone condition monitoring tool, or to supplement existing condition monitoring programs. Description FDA is performed using Gastops' commercially available FilterCHECK, which completes the analysis by backwashing the filter with a clean fluid. The backwashing process creates a slurry entraining all of the particles contained in the filter. First, a sample cycle is completed, where the slurry flows through a 20 pm nylon patch, capturing a representative sample of particles from the filter for a later EDXRF analysis. Then an extensive wash cycle is completed to extract the remaining particles from the filter. The slurry flows through a Gastops' MetalSCAN sensor which quantifies the number of small, medium, and large ferrous and non-ferrous particles. Particle sizes are sorted in accordance with the table below. Bulk EDXRF (Energy dispersive X-ray fluorescence) analysis is then completed on the patch created from the FDA sample cycle, with the results for each detected element output in pg/cm2, and overall concentration calculated. Complementary Techniques • Patch Visual Analysis (TD-FA-002): The patch created during the sample cycle is analyzed using a microscope to identify particle type and morphology of particles captured on the patch. • Chip Debris Analysis - LIBS Method (TD-MA-001): Particles > 80 pm on the patch created during the sample cycle are selected for chip debris analysis. Particle spectra are matched to alloy spectra in a pre-defined library. • Statistical Analysis (TD-CI-001): FDA data is statistically analyzed in accordance with Gastops proprietary methods and industry standards to develop limits representative of machinery condition.

Deliverables Results are delivered in a comprehensive report that includes the following: 1. Counts Data: The count of all ferrous and non-ferrous particles extracted from the filter. Also includes total ferrous mass of particles, and mass per filter operating hours (based on provided filter operating hours). 2. Patch Photo: photo of the patch generated during the sample cycle. 3. Patch EDXRF Results: Patch EDXRF results for 11 elements.
