A spectroscopic measurement system for engine health

LADIES is a early detection device of industrial lubricants aging, developed by Light4Tech in collaboration with Mecoil and CSO and the scientific support of the European Laboratory of Non-Linear Spectroscopy – LENS.

LADIES is a state-of-the-art device capable of quantifying the presence of lacquers and other insoluble residues in lubricating oils, allowing to maintain plants’ efficiency and prevent malfunctions and expensive downtimes.
One need only think that in a power generation plant an oil charge replacement with subsequent circuit cleaning costs about 150.000 euros. Turbine repair can exceed one million euros, its replacement up to 10 millions, not to mention the economic damage for loss of production estimated at about 100,000 euros a day.

It follows that companies in many industrial sectors need to evaluate lubricants wear with devices capable of reducing times and costs of current survey systems ensuring repeatability in measurement. LADIES is the ideal answer to this kind of need, filling an evident void in the market.
Based on a combination of spectroscopic techniques such as Raman effect, fluorescence, and reflection with Principal Components Analysis (PCA), LADIES has the further plus of being compact, thus overcoming another limitation of today’s systems: ideally, only two excitation and detection probes are needed, with detection sources and means placed in remote configuration.

L4T S.r.l. participates in collaboration with Mecoil Diagnosi Meccaniche S.r.l. (leader) and with CSO S.r.l. to the LADIES project – Lubricant’s Aging Detection Instrument for Evaluation of Stress – project co-funded with POR-CReO funds ERDF 2014 – 2020 – Calls for aid for investments in research, development and innovation CSR – Call for proposals 2.
