1.4 DESCRIPTION
The Cantilever transducers were designed to measure
tension in webs having widths of up to 30 inches.
Sensing beams to which semiconductor strain gages are
bonded form a half bridge circuit. With these high signal
output gages a very small force on the roller is shown as
a change in the tension output signal.
The cantilever transducer cartridge is not fitted with a
sensing roll as standard. Provision is made to mount a
sensing roll in the end of the cartridge. Several shaft
diameters can be selected by choosing an appropriate
adapter. The transducer is nearly insensitive to the
location of the net web force along the length of the roll.
The Cantilever tension transducers* are available in two
sizes, 1 and 2 in four different mounting configurations,
S, FL, PB, and BR. There are also “Metric” and
“English” versions of each size. (*U.S. patent #
4326424. Foreign patents upon request.)
The different configurations are made by adding
mounting hardware modules to the transducer
cartridges. In each of the sizes, the transducer
cartridges are available with the connector mounted
either on the side or the end.
The CLTSC-1T and CLTSC-2T cartridges have the
connector located on the side. These cartridges can be
mounted to the machine frame with a single bolt which
goes through the machine frame for the type “S”
mounting.
The flange mounting kit can be clamped onto the groove
near the edge at the end of the type CLTSC-1T and
CLTSC-2T cartridge. The cartridge can then be
mounted to the machine frame by the flange with four
mounting bolts for the type “FL” mounting.
The type CLTEC-1T and CLTEC-2T cartridges have
the connector located on the end. The cartridge can be
converted to a pillow block type transducer by adding
the pillow block (PB) mounting kit. The cartridge is
inserted into the pillow block base and then the lockplate
is bolted to the end of the cartridge. The transducer is
mounted to the machine frame with two bolts through
the pillow block base for the type “PB” mounting.
The type CLTEC-1T and CLTEC-2T cartridges can
also be mounted through the machine frame by using the
type BR mounting kit. The cartridge is inserted through
a hole in the machine frame and then the lockplate is
bolted to the end of the cartridge for the type “BR”
mounting.
