Abstract
Elongation of a moving endless body, such as a chain, a belt, a conveyor or the like, is measured continuously by providing two indices, e.g. pins or tongues, on the endless body, and two sensors, e.g. magnetic or optical sensors, along the path of circulating movement of the endless body. The sensors are connected to an arithmetic circuit which determines elongation from the data provided by the sensors.
