The condition of a chain is monitored by at least one acoustic transducer (ultrasonic transducers) T1, T2 on sensor unit 22 that is fixed to a first link of the chain (for example intermediate link 16, fig 3). The transducer emits an acoustic signal 26 toward a receiver on any link of the chain. The receiver may be on the first link to receive the signal after reflection from a second link 14. That is, the transducers T1, T2 may also receive the reflected signals and therefore serve as transceivers, or the sensor unit 22 may support separate receivers disposed beside the transducers T1 and T2. The second link may be interconnected with the first link or may be opposed to the first link across an intermediate link. In a direct transmission option, the receiver may be on the second link or on another link. By measuring time of flight of the signal from the transducer to the receiver, the distance between the transducer and a link of the chain other than the first link is determined. An increase in that distance indicates a degree of wear at one or more contact interfaces between successive links of the chain.
