摘要： A tension member tension monitoring arrangement and method for measuring tension member tension of elevator tension members of a bundle of tension members, the elevator comprising an elevator car suspended by the tension members, such as ropes or belts, of the bundle of tension members, a termination at one end of a tension member and a mounting plate for attaching the termination relative to the hoistway, counterweight and/or the elevator. The tension member tension monitoring arrangement comprises at least one capacitive pressure sensor arranged in connection with a tension member termination. The arrangement further comprises a control unit connected to the at least one sensor. The at least one sensor is configured to sense the tension member forces of the tension members of the bundle of tension members attached to the tension member termination and generate a signal relating to one or more tension members of the tension member bundle readable and/or measurable by the control unit and proportional to the sensed load or force.
