CC (B - C)
CYLINDRICAL FORCE TRANSDUCER FOR
INDUSTRIAL APPLICATIONS
MECHANICAL DIMENSIONS
Main features
• Range of measurement: from 750 to 1.500 kN
• Accuracy class: 1%
• Internally generated calibration signal
• All stainless steel construction
• Corrosion resistant
• Grade of protection: IP65 ( norme DIN 40050)
The CC force transducers have been designed for use in the
plastics industry where it is required to measure the reaction
force to the extrusion pressure that is present on the casing
of the gearbox along the axis of the extruder screw.
These models, fitted in contact with the thrust bearings,
measure a force whose valve, after suitable correction, is
equal to extrusion pressure multiplied by the screw area.
The CC cylindrical force transducers are all stainless steel
construction and configured in such a way that the body,
airtight welded, acts also as the case, making a unit that is
smaller than the CT series.
The connector in the shank is on the same axis as the
transducer, which in some cases alows easier installation.

ELECTRICAL CONNECTIONS
CONVERSION TABLE
ORDER CODE
If the transducer is
supplied complete with
prewired connection
cable, the colour code is
that indicated in the table.
Cells connected in parallel
In systems that use several cells, the parallel
connection automatically sums the loads on each
individual cell.
Using this method of measurement, the maximum load
will be the sum of the loads on the individual cells and
the sensitivity will be the average value of these cells.
It is important that the user ensures that no cell is
stessed beyond its maximum rating under any load
condition.

APPLICATION NOTES
For a correct use of the transducer, it is necessary to ensure
that the load is evenly distributed over the application surfaces
shown in the diagram.
It is essential to centre the transducer using the circular crow of
diameter A and to apply the load installing the transducer
between two grinded surfaces perpendicular to the direction of
the applied load.
Ex.: CCB - KN7,5C
CC force transducer, model B, measurement range
0 - 750 kN.
If request, it is possible to supply models with non-standard
mechanical and/or electrical
features.
