Publication number: 20240102958Abstract: Various example embodiments described herein relate to a sensor assembly. The sensor assembly includes a first sensor cover and a second sensor cover. The first sensor cover is disposed on a first end of the sensor assembly and the second sensor cover is disposed on a second end of the sensor assembly. The first sensor cover defines a first capillary and the second sensor cover defines a second capillary therethrough. The sensor assembly further includes a first sensing unit, a second sensing unit, and a filter. The first sensing unit and the second sensing unit are disposed between the first sensor cover and the second sensor cover. In some example embodiments, the filter is reactive to a target gas and thereby prevents an inflow of the target gas through the second capillary into the sensor assembly.Type: ApplicationFiled: November 30, 2023Publication date: March 28, 2024Inventors: Qinghui MU, Jianglin JIAN, Feng LIANG, Ling LIU, Na WEI

Publication number: 20230125226Abstract: Apparatus and associated methods relate to a one-piece structure for a solid electrolyte chemical sensor (SECS) having a first surface defining a cavity designed to receive a substrate that retains a solid electrolyte, an internal water impermeable coating on at least a portion of the first surface, a second surface that is substantially coplanar with an adjacent peripheral edge of a top surface of the substrate when the substrate is received in the cavity, and a plurality of electrical contacts disposed on the second surface adapted to electrically couple with the electrodes on the substrate when the substrate is received in the cavity and electrical paths are provided between respective electrical contacts and electrodes. In an illustrative example, the internal water impermeable coating may include a metallic material, such as gold. In various embodiments, the one-piece structure may advantageously prevent water loss from both the sensor substrate and the SECS.Type: ApplicationFiled: December 23, 2022Publication date: April 27, 2023Inventors: Lei XIAO, Feng LIANG, Jianming JIN, Guoqiang NI, Qinghui MU, Sam SU
