Description
General Information
Warner Electric Series 30 Type B Tensioncells
are force transducers especially designed to
measure and control web tension on continuous
strip processing lines. They are normally in-
stalled in matched pairs at each end of a meas-
uring roll. (See Figure 1)
A Tensioncell consists of a unique combination
of two integral systems (one mechanical, the
other electrical) for converting the mechanical
force of strip tension into an electrical signal
which is directly proportional to the strip
tension.
Type "B" Tensioncells are intended for
NON-ROTATING shaft installations. A
self-aligning shaft clamp assures proper
alignment of the measureing roll when the
tension cells are bolted to the machine frame.
Type "B" Tensioncells are supplied in matched
pairs, one to be mounted at each end of the
tension measuring roll. Note that the cell marked
"W2" is a mirror image of "W1". The 'W2" cell
allows for thermal expansion of the shaft.

The Mechanical System
The mechanical system consists of a Patented
"C-Flexure Pivot Assembly" which incorporates
a mounting Base Block, frictionless elastic pivot
(or hinge), and Load Plate. (See Figure 2) When a
mechanical force is applied to the Load Plate,
the pivot permits its deflection toward or away
from the Base Block.
