Publication number: 20200340934Abstract: An installation for following up the evolution of the quality of a lubricant circulating in equipment includes a conduit connected, upstream, to the piece of equipment and downstream to a recovery pan. A first controlled interruption valve circulates the lubricant in the conduit, a buffer reservoir accumulates lubricant, and a first bypass line is connected to the conduit, upstream from the first valve and to the buffer reservoir. A second controlled interruption valve circulates the lubricant in the first bypass line, a second discharge line discharges the lubricant, from the buffer reservoir to the recovery pan and a third controlled interruption valve circulates the lubricant in the second discharge line. A sensor determines content in a predetermined chemical element of a lubricant sample at the outlet of the buffer reservoir. This sensor includes an X-ray source and detector and a sample cell with a poly X-ray window.Type: ApplicationFiled: June 2, 2017Publication date: October 29, 2020Applicant: Total Marketting ServicesInventors: Raphael JUSTON, Yann TROADEC, François CHAUDOREILLE, Jean-Philippe ROMAN, Arnaud AMIOT

Patent number: 10481060Abstract: A density sensor to measure the density of a gas having a density ranging from 30 gram per cubic meter to 150 kilogram per cubic meter and a working pressure ranging from 0 to 100 bar. The density sensor includes a resonator housing, a membrane, an actuating/detecting module mechanically coupled to the membrane, and a resonating element arranged to be immersed in the gas, the resonating element being mechanically coupled to the membrane by a pedestal. The resonating element is a resonating disk having a thickness ranging from 25 ?m to 200 ?m and a diameter ranging from 4 mm to 12 mm. The resonating disk extends parallelly to the membrane or being angled relatively to the membrane and is coupled by its center to the pedestal. The resonating disk is made of a metal chosen among the group comprising stainless steel, nickel-iron alloy and Molybdenum.Type: GrantFiled: September 22, 2016Date of Patent: November 19, 2019Assignee: WIKA TECHInventors: Francois Chaudoreille, Guillaume Granier, Lucia Jimenez
