A device including a chain strand where a contact point of a pivoting arm rests and slides on the chain of the chain strand. The pivoting arm is mounted on the shaft. The pivoting arm is coupled with the source of a compressive force in a form of a weight or a torsion spring. The pivoting arm is coupled with the shaft and therefore with the indicator of tension of the chain strand. The compressive force compensates for the change in resistance and lengthening of the chain when the chain conveyor is running, wherein its chain strand has been pre-tensioned by the basic pre-tensioning force induced by the tensioning device. The co-acting of the pre-tensioning force and the compressive force creates the operating tension which is not only indicated but also optimized by the device of the invention depending on a change in resistance in the chain strand.
