Elevator system having a measuring device for determining a position of an elevator car in an elevator shaft

An elevator system having an elevator car in an elevator shaft comprising:

• a measuring tape for determining a position of the elevator car in the elevator shaft, which is arranged vertically in the elevator shaft, and has optical coding for length measurement;
• at least one marking element that is arranged on the measuring tape and has optical coding;
• a sensor device which is attached to the elevator car and comprises a lighting source and a sensor which form a detection field for detecting the measuring tape;
• an evaluation device for decoding the codings in the detection field;
• and
• a control device for controlling the elevator system as a function of the at least one marking element,
• wherein the at least one marking element is fixedly arranged on the measuring tape,
• wherein the optical coding of the at least one marking element has a same format as a format of the measuring tape,
• wherein the optical coding of the at least one marking element corresponds to a length specification, and
• wherein the optical coding of the at least one marking element has a value outside a length range of the measuring tape.
