So how does a folding beam load cell work?
bending beam load cells tend to be the most widely used varieties of load cells. Go through this
paper to learn more about the benefits and advantages as well as peculiarities of folding beams.
During a measurement, weight loads acts on the load cell's metal spiral fraction and results in
This burden (good or bad) is converted into a strong electrical signal through the strain gauge
(SG) installed on the spring fraction. The major sort of load cell is known as a bending beam
using a strain measure. Often the (required) main pieces, i.e. spring piece as well as strain gauge
are place together with elements (housing, sealing elements, etc.) conserving the strain gauge
bending beam load cells
twisting beam load cells are the best fit for numerous measuring activities. Right here the indicator
on principle depends on the folding moment. The moment the weight application point in the
twisting beam's longitudinal direction shifts with very much the same loads, diversified signals are
As a result of this, the only bending beam is rarely utilised in load cells, as it demands very
special measures to ensure a constant weight application point (lever arm effect).
Many folding beams
Many twisting beams can be used as coil elements for loads as much as 5 t. This weight cell form
mainly applies 2 (twofold folding beam) or couple of (three-way beam) bending beams. The're
combined through tougher things on the clamping and also on the load application side. The
stricter coupling makes sure a purely up-right move of the load application point as well as S-
shaped deformation of the beams.
Fig. 1: Double twisting beam principle
This method is notably less sensitive to weight application point shifts when compared to a single
folding beam. The S-shaped deformation yields bad and the good strain areas on the outside that
are near to each other and sometimes even noticeably aid strain gauge fitting up and in some
cases wiring. Fig. two tells diverse twofold twisting beam types.
