Diagnosing device for e.g. freight elevator, has data transmission unit transmitting measured physical parameters to evaluation unit arranged outside of elevator car and comprising wire connecting evaluation unit with acceleration sensor

摘要

The device has an acceleration sensor (10) installed in an elevator car of an elevator system for measuring several physical parameters of the elevator car. An evaluation unit (8) is arranged outside of the elevator car, and a data transmission unit is provided for transmitting the measured physical parameters to the evaluation unit. The transmission unit comprises a wire (6) that connects the evaluation unit with the sensor.
