Abstract
In a transport device, which comprises at least one endless conveyor guided around at least two guide rollers, a monitoring appliance for monitoring motion of a guide roller is positioned on at least one of the guide rollers. The monitoring appliance comprises a first contact element disposed on and electrically connected with the guide roller, and a second contact element disposed near the guide roller. The first and second contact elements are arranged relative to one another in such a way that an electrical contact between them occurs with every revolution of the guide roller, such that the electric potential of the guide roller is transmitted to the second contact element. Additionally, a substrate treatment apparatus comprising such transport device is disclosed.
