Patent number: 8653839Abstract: A sensor is disclosed for determining a sulfur concentration in a liquid, such as a liquid fuel. The sensor includes a substrate that is at least partially coated with zinc oxide and, more specifically, zinc oxide microstructures. The zinc oxide microstructures have a crystal lattice structure that is oriented in the (002) plane, are oxygen-deficient and have a rod-like microstructure. If the substrate is conductive, it may be connected directly to a working electrode which is connected to a potentiometer which, in turn, is connected to a reference electrode. If the substrate is non-conductive, the conductive layer can be deposited on the substrate prior to deposition of the zinc oxide to form a working electrode. An application of a constant current (or voltage) to either electrode will result in a voltage across (or current flow between) the working and reference electrodes.Type: GrantFiled: January 20, 2012Date of Patent: February 18, 2014Assignee: Caterpillar Inc.Inventors: Douglas Alexander Rebinsky, Orhan Altin, Yong Tian, Ryan A.

Publication number: 20110012625Abstract: Sulfur sensors are formed by coating a conductive substrate with ZnO microstructures that are reactive with sulfur in liquids, such as fuel, using MOCVD. The ZnO is changed to ZnS over time and causes the voltage across the sensors to change under a constant current by at least about 25%. The time required for such saturation to occur can then be correlated to a sulfur concentration in the liquid.Type: ApplicationFiled: June 17, 2010Publication date: January 20, 2011Applicant: Caterpillar Inc.Inventors: Jedidiah M.
