Zusammenfassung: | Abstract A seal assembly for sealing a fluid passageway from contaminants, the fluid passageway formed by a rotating shaft entering an opening in a housing, the fluid passageway connecting an interior of the housing and an exterior of the housing, the seal assembly comprising: a stationary member surrounding the shaft and affixed to the housing; a rotatable member secured to an adjacent portion of the shaft, the rotatable member and the stationary member forming at least a portion of the fluid passage connecting the interior of the housing to the exterior of the housing; a first sealing member having an inner diameter surrounding the rotating shaft and a second sealing member having an inner diameter surrounding the rotating shaft, the first and second sealing members dividing the fluid passage into an interior section exposed to the interior of the housing, an open section exposed to the exterior, and a sealed section fluidly sealed between the interior section and the open section, wherein the length of the inner diameter of the first sealing member is a different length of the inner diameter of the second sealing member; and a sensor disposed within the sealed section, the sensor detecting the contaminants within the sealed section. |
