This patented solution integrates the load cell into the gearbox. The output signal from the transmitter can: • Shut down the e-motor if necessary • Reduce the input power (e.g. by frequency converter) • Elaborate the information by customer PLC (e.g. creating working group graphic in real time) Technical Information • The Load Cell is located between the e-motor and first stage of transmission • It can be fixed with all IEC and gear stages just by changing the interface component Applications Used in all applications with an e-motor where it is necessary to control and manage the input...

For all applications of yaw and pitch drives for the monitoring of load peaks, Bonfiglioli offers its customers a solution that is protectively integrated into the gear motor. The integrated load cell quickly and precisely measures torque and enables torque monitoring in real time. The system provides an automatic engine shut-down to protect the drive or reduce the capacity of the frequency converter and provides information to the PLC. The system also has an anti-seize function which prevents blockages. Rated Torque Range 8000 ... 120000 Nm Peak Torque Range 5000 ... 300000 Nm Reduction...
