Abstract
A chain tensioning sprocket is moveable with a predetermined force into a U-shaped path of a chain to apply continuous tensioning force to the chain. The change in length of the chain is measured by detecting the movement of the chain tensioning sprocket into the U-shaped path of the chain, and measurement of movement of the chain tensioning sprocket indicates a change in the length of the whole chain, which, in turn, indicates the wear on the parts of the chain and the expected operative life of the chain.
