New Digital imaging particle counting gives broad micron counts 4, 6, 14, 21, 38, 70 and >100 microns ISO, NAS, SAE counts Shape recognition Particles are categorised as Sliding, Cutting and Fatigue Wear as well as Fibres Air bubbles are counted and removed from the counts High resolution images are stored for reporting Particles can be sized on the screen via the software to aid reporting The ability to self-prime, pump and measure oil up to 2,400cst Self-contained unit with battery and internal stepper motor pump Accessory case with measurement flasks, vacuum thief pump etc. included Additional sensors included: Water sensing %RH (tracked against temperature) Remaining life of the oil via a TanDelta sensor A database of over 500 oils are included with calibrated degradation curves Ability to self-calibrate any oil not on the database Export data to .xls, pdf and .jpg for the images collected Case study A n OEM of large off-highway equipment was experiencing continuous particle counter inaccuracies at a verification stage of assembly. The rejections due to fluid condition were mounting, causing delayed shipments and significant related costs. The average holding time delay due to rejection was seven days, which incurred a holding cost of £1000-a-day per unit. At the consultation phase of the case study, eight units had been delaye d. The diagnosis was in: the existing laser light-blockage-type particle counters were providing inconsistently high and erroneous particle counts. The ISO 4406 cleanliness would frequently measure 23/22/19, despite a strong fluid-maintenance and conditioning regime. Third-party fluid analysis reports and fluid datasheets suggested that the synthetic hydraulic fluid contained a high concentration of a siloxane (silicone derivative) antifoaming additive, known to cause phantom particle measurements in LBM automatic particle counters. Filtertechnik provided an extensive on-site demonstration that proved the advanced digital imaging technology of the Particle Pal Pro portable fluid contamination monitoring solution, which measured an average ISO fluid cleanliness of 15/14/10. This allowed the customer to successfully process the fluid and pass six units during the first day of demonstration. The two remaining backlogged units passed early on the second day of demonstration. The savings evidenced by the demonstration equated to approximately 35% in cost savings and an 81% reduction in holding time. www.filtertechnik.co.uk The Particle Pal Pro is equipped with the S120 digital imaging particle counter and, together with water and oil degradation sensors, delivers a powerful on-site oil analysis instrument. www.hpmag.co.uk HYDRAULICS & PNEUMATICS April/May 2021 25 STAINLESS STEEL HYDRAULIC HOSE AND PIPE FITTING SPECIALISTS We are the leading manufacturer and stockist of stainless steel hose fittings, tube fittings and adaptors.
