A sealing system comprising: a first rotatable seal runner; a first stationary sealing member that includes a first base and a first nose that extends from the first base in an axial direction and interfaces with the first seal runner; a first carrier that supports the first sealing member; a first tab coupled to the first carrier, wherein the first tab extends from the first carrier in the axial direction towards the first seal runner, wherein when a portion of the first nose is worn, the first tab contacts the first seal runner, and wherein the portion of the first nose is less than an entirety of the first nose; and a sensor or detection device configured to detect and indicate when a portion of the first tab is liberated from a remainder of the first tab in an amount that is greater than a first threshold; characterised by: a second rotatable seal runner; a stationary second sealing member that includes a second base and a second nose that extends from the second base in the axial direction and interfaces with the second seal runner; a second carrier that supports the second sealing member; and a second tab coupled to the second carrier, wherein the second tab extends from the second carrier in the axial direction towards the second seal runner; wherein the sensor or detection device is configured to detect and indicate when a second portion of the second tab is liberated from a remainder of the second tab in an amount that is greater than a second threshold; wherein the first tab includes a first material and the second tab includes a second tab material that is different from the first material; and wherein the sensor or detection device is configured to provide an identification of the first sealing member when the sensor or detection device detects the first material is present in the amount greater than the first threshold, and wherein the sensor or detection device is configured to provide an identification of the second sealing member when the sensor or detection device detects the second material is present in the amount that is greater than the second threshold. a first rotatable seal runner;
