It is intended for pure force measurement, but targeted at applications involving large moments/moment arms. The loadcell is designed to be bolted to a large, flat surface and used as a bracket to support a cantilever beam. A cantilever bracket loadcell can be used at both ends to fully support the beam, provided thermal expansion is allowed for somewhere in the system. The F320 can also be mounted against a floor or ceiling plate to act as a strut support in much the same way. The F320 is able to support large sideloads without effecting measurements.
The binocular bending beam construction has good moment immunity resulting in very small errors for changes in the force application point. This point may vary not only in terms of distance along the cantilever beam, but also in a manner that would apply a small torque around the axis of the beam. Although the loadcell is compensated for induced errors, there is a maximum supported moment for each range. Standard F320 loadcells can withstand full rated load at half a metre full cantilever. Further details are given in Engineering Sheet E037. It is important to contact our engineering department to discuss loadcell selection to suit any load application or range.
We are happy to design variants of this loadcell to meet your specific requirements. Versions can be manufactured for fully compensated operation up to +250°C. Please consult our engineering department.
