About the ALF330 Load Cell

The ALF330 low range load cell has been developed to meet a growing need for high resolution, low range force
measurement with minimal translational deflection. The high stiffness of these load cells, 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 ALF328 and ALF329 load cell product types offer excellent performance but rely on a comparatively low stiffness strain mechanism. The ALF329 in particular requires a reduced output sensitivity in order to maintain
some level of robustness. The ALF330 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 load cells. Other housing designs and fixing arrangements are therefore possible.
