Patent number: 8336375Abstract: A flow cell assembly for fluid sensors is provided. The assembly includes a housing configured to couple to an external source of fluid for measurement. The assembly further includes a flow regulator and a flow meter disposed within the housing to facilitate controlled fluid. The housing defines one or more measuring chambers each configured to receive a fluid sensor. Each measuring chamber includes an inlet aperture and a gravity overflow spaced apart from the inlet aperture. Each measuring chamber is configured to receive a fluid sensor such that a sensing end of the fluid sensor is disposed proximate to an inlet aperture of the measuring chamber, thereby ensuring controlled fluid pressure proximate to the sensing end.Type: GrantFiled: June 18, 2010Date of Patent: December 25, 2012Inventors: Anthony Thai, Steven Wells, Gert Burkhardt

Patent number: 8317989Abstract: An electrochemical sensor is provided that includes a housing having an outer wall, an axial bore circumscribed by the outer wall, and a barrier wall that aids in defining a reference cavity. The housing further including a plurality of cross members in spaced relation to one another disposed between the axial bore and the outer wall, each cross member defining an aperture. A junction plug is disposed at the distal end of the housing. The junction plug comprises a porous material that enables ionic flow through the junction plug. The sensor enables ionic communication between the target fluid and the reference electrode within the reference cavity through the apertures of the plurality of cross members. In this manner, the sensor provides generally a long, tortuous flow path, or salt bridge, between the target fluid and the reference electrode, resulting in a high resistance factor for the sensor.Type: GrantFiled: January 18, 2011Date of Patent: November 27, 2012Assignee: Georg Fischer Signet LLCInventors: Steven Wells, Gert Burkhardt, Anthony Thai

Patent number: 8211282Abstract: An electrochemical sensor is provided that includes a housing having an outer wall, a plurality of longitudinal chambers disposed within the outer wall, and a reference chamber housing a reference electrode. Ionic communication between the target fluid and the reference electrode must pass sequentially through each of longitudinal chambers from a first longitudinal chamber to the reference chamber. In this manner, the sensor provides generally a long, tortuous flow path, or salt bridge, between the target fluid and the reference electrode, resulting in a high resistance factor for the sensor.Type: GrantFiled: September 15, 2010Date of Patent: July 3, 2012Assignee: Georg Fischer Signet, LLCInventors: Steven Wells, Gert Burkhardt, Anthony Thai
