S-Beam
S-Beam load cells derive their name from their shape which,
of course, is the shape of the letter S. The S-beam is normally
used in tension applications. However, there are S-beams
available which are bidirectional. They are primarily used for
mechanical-to-electronic scale conversions, platform scale
and general purpose weighing applications. They vary in size
from as low as 25lbs to as high as 20,000lbs. When mounting
an S-beam, remember to include the side from which the
cable extends is the dead portion of the system. Movement of
the cable in the live part of the system can be a source of
weighing errors.

Platform
The platform load cell is sometimes called a dual-guided
cantilever beam cell but is more commonly referred to as a
single point cell. They are used in light capacity bench scales.
They are most commonly made out of aluminum. Some
platform scales have built-in overload stops. Safe overloading
of 150% full scale is permissible at the center loading point on
some platform load cells. They are commonly made in 2kg
through 1000kg and 2lbs through 1000lb sizes. The bridge
resistance is commonly 350Ω. See Figure 1-4 Platform Load
Cell.
