Abstract
A mechanical seal assembly comprising a gland assembly having first and second sensor openings and a sleeve assembly disposed about a shaft and disposed within the gland assembly. A first RFID sensor is disposed within the first sensor opening and a second RFID sensor is disposed within the second sensor opening, where the first RFID sensor is a high frequency RFID sensor and the second RFID sensor is an ultra high frequency RFID sensor.
Claims6
A mechanical seal assembly, comprising
- a gland assembly having a housing that includes a plurality of sensor openings formed in an outer surface of the housing, wherein the plurality of sensor openings includes a first sensor only opening and a second sensor only opening, and wherein the first and second sensor openings have a depth that does not extend to an inner surface of the housing,
- a sleeve assembly disposed about a shaft and disposed within the gland assembly,
- a rotary seal ring rotatably coupled to the sleeve assembly,
- a stationary seal ring disposed in operative contact with the rotary seal ring to form a seal therebetween, and
- a first sensor disposed within the first sensor only opening and a second sensor disposed within the second sensor only opening,
- wherein the first and second sensors are RFID sensors, and wherein the first sensor is a high frequency RFID sensor and the second sensor is an ultr high frequency RFID sensor.
