Track assembly having a wear monitoring system

A track assembly for a mobile machine, comprising:

• a chain assembly including a plurality of track links;
• a traction assembly including a plurality of track shoes carried by the plurality of track links;
• a drive sprocket;
• an idler assembly including an idler and a mount;
• a roller assembly including a plurality of rollers and a roller frame;
• and
• a wear monitoring system, including:
• at least two detection sensors, each configured to direct a beam at a location that does not change as a result of wear of components of the track assembly, and each detection sensor being configured to generate a first signal indicative of a first position of a component of the track assembly when a first feature of the component interrupts the beam, and a second signal indicative of a second position of the component when the first feature of the component no longer interrupts the beam, wherein the component is configured such that wear of at least another component of the track assembly causes the component to move to the second position from the first position;
• and
• a controller in communication with the at least two detection sensors, the controller being configured to determine an amount of wear experienced by the track assembly based on the first signal and the second signal,
• and
• wherein each of the at least two wear sensors is one of a camera sensor, a detection sensor, or a distance sensor.
