The PressductorP difference
Like ABB's other load cells based on Pressductor
Technology, PillowBlock Load Cells rely on ectto-
magnetic changes in the transducer, not on physical
movement, to sense fluctuations in web tension.
The Pressductor" Technology operating principle
provides exceptional improvements in load cell
performance characteristics, including reliability
(notably absence of drif), durability, repeatabiliy,
and wider measurement range.
Machined from a solid block of steel, the
load cells are rugged and siff, affording high
overload protection as well as an extended mea-
surement range above the nominal capacity. And
they won't contribute to machine vibration, even
at high speeds.
Since the transducer action - the magnetic
flux - takes place inside a steel core, environmen-
tal factors like dirt or fluids can't degrade perfor-
mance and reliabiliy.
Furthermore, low transducer impedance - less
then a couple of ohms - helps eliminate suscep-
tibility to radio frequency and elecromagnetic
interference.

How the Measurement Signal Is Generated
Two commonly used transducer types - the strain
gauge and the LVDT transducer - rely on physi-
cal movement in the
transducer to produce a
measurement signal (see
Strain gange: Sretching alers drawings). Stretching，
reistance of ectrial circuits. compression or bending
motions are prerequisites for signal generation.
ABB's exclusive Pressductor Transducer produces
a signal as a result of changes in an electromagnetic
field. This operat-
ing principle has its

I n many web processes, the web tension imher-
ently produces a horizontal force component on a
ol... or, by design, it can be made to do so. Paper
machines and machinery processing plastics, foils
or textiles are typical examples.
Using this horizontal force component to
measure web tension can be highly advanta-
geous. The load cell can be sized to measure
just the web tension, excluding the tare weight
of the roll, which, on a big paper machine, for
example, can be far greater than the tension in
the sheet. The result is optimized measurement
accuracy.
