A seal monitoring system includes at least one sensor configured to couple to an outer surface of a housing and to output a sensor signal indicative of deformation of the housing. The housing is configured to receive an insert within an internal cavity of the housing, and an engageable seal is configured to selectively establish a seal between the insert and the housing. The seal monitoring system also includes a controller communicatively coupled to the at least one sensor. The controller includes a memory and a processor, the controller is configured to determine a degree of engagement of the engageable seal based on the deformation of the housing. Additionally or alternatively, the controller is configured to determine a fluid pressure within the housing based on the deformation of the housing.

A sealed joint assembly includes a plastic component. The sealed joint assembly also includes a metal component, wherein the plastic component and the metal component define a cavity in an assembled position. The sealed joint assembly further includes a room temperature vulcanized (RTV) material sealant disposed within the cavity. The sealed joint assembly yet further includes a buffer component disposed within the cavity, wherein the buffer component is in contact with the plastic component and the metal component.

A sealing arrangement (100) for a shaft, including at least a first seal element (10a) arranged around the shaft (30); at least a second seal element (10b) arranged around the shaft (30); wherein the first (10a) and second (10b) seal element include adjustable seal elements, wherein the first (10a) and second (10b) seal element include, respectively, an outer shell (14a,14b) of elastic material and a hollow core (12a,12b), wherein the hollow core (12a,12b) of the first (10a) and/or the second (10b) seal element is pressurized with a fluid for an adjustable sealing effect.

A method for controlling a sealing arrangement for a shaft including: setting a first pressure inside a first annular hollow core of a first annular seal element arranged around the shaft, wherein the first seal element includes a first annular elastic casing surrounding the first annular hollow core and the first annular elastic casing; setting a second pressure inside a second annular hollow core of a second seal element arranged around the shaft, wherein the second seal element includes a second annular elastic casing surrounding the second annular hollow core; monitoring the first pressure inside the first annular hollow core and/or the second annular hollow core; and adjusting the first pressure inside the first annular hollow core and/or the second annular hollow core to adjust sealing of the shaft by the first annular seal element and/or the second annular seal element.

Robotic systems and methods for tank seal inspection. A tank inspection robot includes a housing containing a drive assembly, and wheels disposed outside of the housing and operably coupled to the drive assembly.
