ABB PFCL-201C-10KN Pressductor PillowBlock Load Cell 10 kN for Vertical Force and Strip Tension Measurement

ABB PFCL-201C-10KN Product Overview

The ABB PFCL 201C is a force transducer developed for vertical
measurement in PillowBlock mounting arrangements. The load cell is
installed beneath a bearing housing and measures the vertical force
transmitted through the bearing arrangement.

This design is particularly useful in strip processing equipment where
the tension of a moving strip must be determined indirectly from the
forces acting on a measuring roll. The load cells are positioned beneath
the bearing housings of the measuring roll and detect the relevant force
components.

The PFCL 201 family is available in several rated capacities while
maintaining the same general external dimensions. The PFCL-201C-10KN
represents the 10 kN rated-capacity version, making it suitable for
installations where the expected vertical measurement force falls
within the corresponding measurement range.

Pressductor Measurement Technology

The PFCL 201C uses ABB Pressductor technology, a force measurement
principle based on the magnetoelastic effect. When mechanical force is
applied to the sensing element, the magnetic properties of the material
change. The resulting magnetic changes are used to generate the
measurement signal.

Unlike conventional strain-gauge load cells that rely on physical
deformation of a sensing element, Pressductor technology detects the
effect of mechanical force through magnetic characteristics of the
material. This construction contributes to the robust characteristics
of the PFCL 201 series.

ABB describes Pressductor technology as providing high tolerance to
overloads, shock, and impact. The technology is also intended to provide
a high degree of immunity to dust and corrosion, which is particularly
useful in industrial process environments.

10 kN Nominal Load

The defining specification of the ABB PFCL-201C-10KN is its 10.0 kN
nominal load, also referred to as rated capacity. This corresponds to
approximately 2,250 pounds of force according to ABB’s published
conversion data.

The extended load for the 10 kN version is 15.0 kN. ABB also specifies
an overload capacity of 100 kN in the measurement direction. These
values illustrate the mechanical robustness of the PFCL 201 construction
and its ability to withstand substantially higher forces than the
nominal measuring load.

The nominal load should not be interpreted as an unrestricted operating
target. The actual force applied to the sensor must be evaluated in
accordance with the installation arrangement, force direction, bearing
housing geometry, measuring roll configuration, and applicable ABB
installation instructions.

Vertical Force Measurement

The PFCL 201C is designed primarily for vertical force measurement.
ABB documentation describes the sensor as a vertical measuring
PillowBlock load cell that can determine the vertical force component
acting through a bearing housing.

In strip tension systems, the measuring roll receives forces generated
by the strip as it passes around the roll. The resulting force vectors
depend on the strip path and wrap angle. The PFCL 201C detects the
relevant vertical force component, which can then be processed by the
associated tension measurement electronics.

The measurement direction is therefore an important part of installation.
Correct orientation and mechanical mounting are necessary to ensure that
the applied force corresponds to the intended measurement direction.

Construction and Mechanical Design

ABB specifies that the PFCL 201C load cell is machined from a single
piece of stainless steel. The sensors are machined directly into the
steel structure and positioned so that they are sensitive to force in
the intended measurement direction while being less sensitive to forces
in other directions.

The solid construction provides a rigid mechanical structure suitable
for industrial force measurement. The load cell is mounted on a base
using four screws, while the bearing housing is mounted on top of the
load cell using another four screws.

ABB also states that PFCL 201 load cells are calibrated and temperature
compensated. This is important for industrial force measurement because
changes in temperature can influence the characteristics of measurement
components.

PFCL 201C Connector Design

The PFCL 201 family is available in several construction variants.
The PFCL 201C is equipped with a connector for a pluggable connection
cable. This distinguishes it from the PFCL 201CE and PFCL 201CD
versions, which use different fixed-cable arrangements.

The connector-based configuration of the PFCL 201C provides a practical
electrical connection arrangement for strip tension measurement systems.
The associated cable and connection system must be selected and installed
according to the applicable ABB documentation.

When identifying a PFCL 201C, the connector arrangement is therefore
one of the useful physical characteristics for distinguishing the model
from other PFCL 201 variants.

Strip Tension Measurement Applications

The PFCL 201C is particularly suitable for strip tension measurement
systems used in metal processing equipment. Typical applications
include rolling mills and continuous process lines where strip tension
must be monitored during production.

ABB identifies applications including annealing, pickling, and
galvanizing lines. These processes can involve demanding mechanical
and environmental conditions, making robust force measurement an
important part of the overall control system.

The load cell itself forms one part of a complete strip tension
measuring system. The system can include load cells, cabling, adapter
plates, control electronics, junction boxes, and output signals.
The force information generated by the PFCL 201C can therefore be
processed by the associated ABB measurement electronics.

Mechanical Installation

Correct mechanical installation is essential for the PFCL 201C because
the sensor measures force according to its defined measurement direction.
ABB documentation describes a mounting arrangement in which the load
cell is positioned between a supporting base and the bearing housing.

The base connection uses four mounting screws, while the bearing
housing is mounted using four screws on the upper side of the load
cell. The mounting surfaces and mechanical alignment should correspond
to the dimensional requirements specified by ABB.

External forces that are not part of the intended measurement can
influence the resulting signal. The installation should therefore
maintain the required force direction and comply with the permitted
transverse-load conditions.

Overload and Industrial Durability

A significant characteristic of the PFCL 201C is its high overload
capacity. For the 10 kN version, ABB specifies an overload capacity
of 100 kN in the measurement direction. This is ten times the nominal
load rating.

The robust mechanical structure is also intended to tolerate shock
and impact conditions that can occur in industrial machinery. The
stainless-steel construction provides resistance to environmental
influences such as dust and corrosion.

These characteristics make the PFCL 201C suitable for force measurement
systems operating around large process machinery where mechanical
loads can vary significantly during normal operation.

PFCL 201C Compared with Other PFCL 201 Versions

ABB provides the PFCL 201 family in several connection configurations.
The PFCL 201C uses a connector for a pluggable connection cable.
The PFCL 201CE uses a fixed connection cable with a protective hose,
while the PFCL 201CD uses an acid-proof cable gland with a fixed
PTFE-insulated connection cable.

The PFCL 201C, PFCL 201CE, and PFCL 201CD versions share the same
general load-cell family and are available in the same four nominal
load ranges. The distinction between these variants is primarily
related to their cable and connection construction.

Therefore, the “C” in PFCL 201C is important when identifying the
physical connection version and should not be omitted from the model
description.

Identification of ABB PFCL-201C-10KN

The product should be identified using both the model designation
and the nominal load. The designation PFCL 201C identifies the
connection and construction version, while 10 kN identifies the
rated capacity.

The complete identification can also be confirmed from the product
label, dimensional characteristics, connector arrangement, and
associated system documentation. This is useful when distinguishing
the 10 kN version from the 5 kN, 20 kN, and 50 kN versions of the
same PFCL 201 family.

The ABB PFCL-201C-10KN should therefore be described as a 10 kN
Pressductor PillowBlock load cell for vertical force measurement,
rather than as a general-purpose weighing sensor.

Conclusion

ABB PFCL-201C-10KN is a 10 kN Pressductor PillowBlock load cell
designed for vertical force measurement and strip tension systems.
It belongs to the ABB PFCL 201 family and is specifically configured
with the PFCL 201C pluggable connector arrangement.

The 10 kN version provides a nominal load of 10.0 kN, an extended
load of 15.0 kN, and an overload capacity of 100 kN in the measurement
direction. ABB also specifies 0.020 mm deflection at nominal load
and a 500 kN/mm spring constant for this capacity.

Its one-piece stainless-steel construction, Pressductor measurement
technology, vertical measuring direction, and high overload tolerance
make the PFCL-201C-10KN an important component for industrial strip
tension measurement systems. Correct mechanical orientation, mounting,
cable connection, and force direction are essential for integrating
the load cell into the complete measurement system.
