Abstract
A sensor assembly includes a wear sensor and a seal member. The wear sensor has an encapsulation body with a wear face, a sacrificial conductor embedded within the encapsulation body and spaced apart from the wear face, and a monitoring lead extending into the encapsulation body and connected to the sacrificial conductor. The wear sensor is fixed relative to the seal member and the encapsulation body has a wear coefficient that is greater than a wear coefficient of the seal member. Bearing arrangements and methods of monitoring seal wear in bearing arrangements are also described.
