2 Description of the BROSA rod end load cell
.1 Structure and functionality
BROSA type 0110 rod end load cells transmit and measure the tensile/compressive force
between two plane-parallel surfaces, the distance between which is mechanically bridged by
the rod end load cell.
Figure 1: Structure of a rod end load cell
The rod end load cell consists of a cylindrical measuring body that absorbs the load (1), the
ends of which (1a) are used for direct connection with the surrounding construction or for
receiving connecting means. As a standard, these elements are designed as inside or outside
threads which can for example be used for receiving fork or articulated heads with comparable
connection means; these may be obtained from BROSA. The combination of an inner thread
on one end with an outer thread on the other head as well as special designs with application-
specific connection geometry is possible. In some cases, there is a connection support ( )
firmly connected to the measuring body, on which - if not placed directly on the measuring
body - the necessary elements for the electrical connection (plug or cable, 3) are attached and
which - if not placed in the measuring body - contains the measurement electronics. The
measuring body and connection support, if applicable, are made of stainless steel.

Figure : Installation conditions
The rod end load cell (1) is connected to the surrounding construction directly or using
connection means ( ; here: articulated heads). Force F transmitted from the connection is
transmitted to the measuring electronics through analysis of the resulting deformation of the
measuring body and output as an electric signal. Versions with two measuring systems, either
with output signals on separate connectors/cables or combined in one connector/cable, are
available as options. More information can be found in the technical datasheets, which may be
obtained free of charge from BROSA.
WARNING! An insufficiently rigid surrounding construction, inadequate force
transmission or inadequate surface condition of the force-carrying surfaces affect the
measurement result!

3 Advice on the safe handling of BROSA rod end load
cells
WARNING! Non-compliance with the following instructions can lead to sensor damage
and/or impairment of measurement results. The analysis of an erroneous measurement can
result in personal injury or material damage.
WARNING! Despite their robust design, BROSA rod end load cells may not be used for
any use beyond the intended purpose (see section 1.1). In the case of non-intended use,
hazards to life and limb of the user or third parties and/or damage to the device in which the
rod end load cell is installed or to other material goods.
3.1 Handling
WARNING! BROSA sensors contain high-quality measurement electronics. Make sure
they are handled carefully.
- BROSA rod end load cells are supplied in transport-safe packaging. We recommended
that you remove the sensors from the package immediately prior to installation.
- The mass of the rod end load cell should be taken into account for the selection of
handling and/or lifting devices; it is indicated on the nameplate.
- BROSA rod end load cells must be secured against falling. Do not throw sensors!
- Use as a tool (e.g., impact, slotting or lever tool) is not permitted; it can cause
damage to the sensor and thus falsify the measurement results.
3. Installation and commissioning
3. .1 General information
We recommended taking the following actions in the given order using the “four-eye
principle”.
a) Inspecting the sensor - measuring point assignment: It must be ensured that the
sensor to be installed is designed for use at the intended measuring point. For this
purpose, check information on the nameplate, in particular the item or the

identification number and the measuring range, against the data of the measuring
point.
WARNING! A sensor not designed for the particular measuring point must not be
installed.
b) Inspection of the sensor for intactness and function: It must be ensured that the
sensor to be incorporated is free of damage of any kind.
WARNING! A damaged sensor must not be installed!
c) Installation of the sensor in the measuring point: The compression load cell is to be
aligned on the intended contact surface according to the offer drawing.
WARNING! The rod end load cell must not be aligned using impact tools!
After alignment, the rod end load cell must be secured against movement and rotation using
the elements provided for this purpose. Ensure that the rod end load cell is correctly aligned
with the intended measuring direction (see marking on the face, see section 1. )
WARNING! A misaligned sensor leads to erroneous measurement results!
d) Establishment of electrical connection: The elements on the sensor for the electrical
connection are to be connected to the power supply, the earth connection if
necessary, and the evaluation system of the device. In doing so, the information
given on the nameplate for plug or cable assignment and, if applicable the installation
guidelines of the cable, are to be observed.
WARNING! An incorrect or incomplete electrical connection impairs or prevents
measurement.
e) Functional check: After completed mechanical (see c) and electric (see d) installation,
load on the sensor is to be applied over the entire measuring range; the output
measurement signals are to be subjected to a plausibility check.

WARNING! If due to unusual events (e.g., deformation or unusual noise),
measurement results are considered implausible or there is suspicion that the sensor is
malfunctioning for any other reason, it must not be put into operation.
3. . Additional information for operation in areas subject to explosion hazards
Only those sensors with the corresponding labels are approved for use in areas subject
to explosion hazards.
If the open cable end is connected inside an area subject to explosion hazards, the connection
must be inside a terminal box/switching cabinet certified in accordance with the ATEX-
directive. If it is connected outside an area subject to explosion hazards, it must be in line with
the general requirements for electrical equipment.
3.3 Operation and maintenance
3.3.1 Operation
BROSA rod end load cells work independently, attaching tools is required for their operation.
Direct manual intervention by the operator is not necessary; there are therefore no
requirements for the operator to wear protective equipment during operation. However, the
requirements towards the device in which the rod end load cell is installed must be observed.
BROSA rod end load cells emit neither noise nor non-ionizing radiation.
Operation of BROSA rod end load cells is permitted only within the parameters and
properties given in the technical datasheets and on the nameplate. These are, among others:
- Measuring range
- Temperature range
- Permissible supply voltage
- Electrical protection class
- Material
It must be ensured that no parasitic influences such as forces or torques transverse to the
direction of measurement are transmitted via the rod end load cells.
Inductive or capacitive coupling with the connection cable(s) of the sensor can distort the
measurement result and must be avoided. Some examples of these kinds of couplings can

be caused e.g., by unfavourable cable routing (parallel power lines, frequency converters,
transformers, motors, incorrect grounding/shielding and the like).
When performing electric welding in the vicinity of the sensor, all connections must be
disconnected and isolated. It must be ensured that no welding current is flowing through the
sensor.
WARNING! Operation outside the specified parameters or contrary to existing
properties or improper use can damage the sensor and cause it to fail or lead to faulty
measuring results. If the sensor is overloaded, this can lead to the whole machine being
equally overloaded and possibly endangering its stability.
3.3. Maintenance
As sensors, BROSA rod end load cells are basically maintenance-free. As load-transmitting
elements, however, they are subject to mechanical stress, requiring regular inspections of the
fault-free state of each rod end load cell. The intervals between inspections depend on the
intensity of use and must be determined by the end-user.
An inspection includes the following points:
- Visual inspection for damage to the measuring body and wiring as well as
contamination.
- Function test/plausibility check
The causes of existing errors are to be identified and remedied. If the test indicates an improper
sensor state, it must be taken out of operation. If a malfunction or damage is detected on the
sensor, it must be sent to the manufacturer's factory for diagnosis and, if necessary, repaired.
WARNING! The sensor may only be repaired at the factory. Intervention (e.g., opening,
mechanical processing and the like) done by parties other than the manufacturer means the
safe operation of the sensor is no longer ensured and voids the guarantee and warranty.
3.4 Disassembly
We recommend performing the following actions in the order given.
a) Ensuring freedom from loads at the measurement position: The rod end load cell
should be unloaded before disassembly.

WARNING! The disassembly of a rod end load cell under load leads to high risks to the
life and limb of bystanders and can cause severe material damage. This is therefore not
permitted.
b) Undoing the electrical connection
c) Remove the mechanical securing elements
d) Disassembly of the rod end load cell
WARNING! If the rod end load cell is to be reused, it must not be removed using
impact tools!
3.5 Disposal
If the end of the service life is reached, the rod end load cell is to be disposed of in an
environmentally friendly way. Since the non-metallic components constitute a small part of
the mass of the rod end load cell, the rod may be recycled as a whole as scrap steel.
BROSA sensors are usually made of stainless steel and can be disposed of accordingly.
If the sensor is stored before final disposal, an appropriate storage location is to be selected
which prevents harmful substances from entering the environment. If necessary, the sensor
must be cleaned.
WARNING! BROSA rod end load cells contain trace amounts of environmentally
hazardous substances. This is also true of the impurities created during use. Contamination
of the environment by these substances is to be prevented.
