Abstract
At least one single link of a conveyor chain is configured to support a tension load cell. A main body portion of the link includes a central cavity sized to contain the load cell, which has been inserted therein through an opening of the main body portion, and at least one auxiliary cavity to contain at least one battery cell and circuitry. A cap portion of the link closes off the opening into the cavity to enclose the load cell therein. One or both of the main body and cap portions may include a bore to receive a fastener for attaching to an end of the inserted load cell, and both portions include a bore oriented to receive a pin of a mating dual link of the conveyor chain. The cap portion may also include anti-rotation surfaces to mate with one or both of: the load cell and the opening.
