DD51-E-RF is an innovative electronic position indicator that uses radio frequency technology to transmit data to a control unit. Such position indicators are used on packaging and filling machines to set and control a variety of machine functions and to read the position of a machine component in the process. Radio transmission eliminates the need for connection cables, and a simple, paperless operation eliminates human error during set-up. The efficiency gains and resource savings associated with this patented technology convinced the judges.
