I-A GENERAL INFORMATION
Comptrol Series 36 Type “B” and “C” Tensioncells are
force transducers especially designed to measure and
control web tension on continuous strip processing lines.
They are normally installed in matched pairs at each end
of a measuring roll. (See Figure 1 & 2)
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”
Type "B" Tensioncells are designed for use in NON-
ROTATING shaft installations. A self-aligning shaft clamp
assures proper alignment of the measuring roll when the
Tensioncells are bolted to the frame of the machine. Type
"B" cells are supplied in matched pairs, one to be mounted at
each end of the measuring roll. Note that the cell marked
"W2" is a mirror image of "W1". "W2" allows for thermal
expansion of the shaft. (See Figure 1)
Type “C”
Type "C" Tensioncells are intended for ROTATING shaft
installations. They are supplied with self-aligning ball
bearings to assure positive alignment of the measuring
roll. Type "C" 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 rotating shaft. (See Figure 2)
I-B 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 3.) When a mechanical force is
applied to the Load Plate the pivot permits its deflection
toward or away from the Base Block. ·
