The F330 low range loadcell has been developed to meet a growing need for high resolution, low range force measurement with minimal translational deflection.
The high stiffness of these loadcells, combined with their robust construction, lends themselves particularly well to dynamic and/or fatigue applications.
The minimum fatigue life of 108 fully reversed RL cycles can be greatly extended if the cycles occur below full rated load.
Both the F328 and F329 loadcell product types offer excellent performance but rely on a comparatively low stiffness strain mechanism. The F329 in particular requires a reduced output sensitivity in order to maintain some level of robustness. The F330 on the other hand offers some advantages over both and also benefits from a purely mechanical resistance to sideloads and vectors. Sideloads up to 25% RL can be withstood for as little as 2% RL error. Similarly, misalignment of up to 3° swept 360° around the measurement axis typically yields no more than 1% RL error.
The strain section within the housing is a separate monocoque structure, allowing repairs to be made quickly and cheaply in comparison to other low range loadcells. Other housing designs and fixing arrangements are therefore possible. The F331 offers the same ranges and performance in a rectangular housing.
We are happy to design variants of this loadcell to meet your specific requirements. Please consult our engineering department.
