Vishay Intertechnology has announced the Vishay Nobel crane-weighing solution from Vishay Systems.

It incorporates Vishay load cells and Vishay instrumentation for logging time, position and weight to optimise service and maintenance intervals.

The crane-weighing solution complies with European crane standard FEM 9.755, which establishes calculation of service intervals and life-cycle measurement parameters for cranes above 1,000kg.

The Vishay Nobel crane-weighing solution uses double-ended shear beam load cells with I-beam cross-sections and G4 advanced process control instrumentation.

The Atex-approved load cells feature capacity from 0.5kN, combined error of 0.2 to 0.5 per cent of RO, and a cable or connector interface.

G4 process control instruments have four base mounting options: DIN rail, panel, desktop and harsh environment.

All G4 models feature flexible configuration, synchronised sampling of all channels, an update rate of up to 800 updates per second, integrated and flexible digital I/O, parameter backup and restoration via USB port or internal memory, and communication via Ethernet, Profibus, Devicenet, Modbus, USB, RS485, RS232 and Modbus/TCP.

The crane-weighing solution, which is applicable to new and existing cranes, connects up to eight load cells in individual channels, sums all channels, controls and logs overload, performs standard weighing functions, and displays total weight and difference between crane sides.

It also sets values for up to 32 load levels, logs up to three different operation times, compensates for faulty load cells, enables data downloading onto memory sticks and enables communication via fieldbus or analogue output.

Collection of information such as weight, time and engine running hours enables better crane security and enhanced safety.

Other benefits include longer lifetime of cranes and optimised service intervals, which result in cost savings.

Vishay Nobel G4 software can be tailored to meet customer requirements.
