ABSTRACT:
A safety device for an automatically operating installation determines at least one movement variable of a moving installation part in a safety-related manner. The safety device includes an acceleration sensor and an evaluation unit. The acceleration sensor is adapted to be coupled to the moving installation part in order to detect any acceleration of the moving installation part. The evaluation unit determines a movement velocity and/or a movement travel of the installation part on the basis of the acceleration.
