2 Desc iption of the BROSA shea fo ce t ansduce
.1 Structure and functionality
The BROSA type 0 10 shear force transducer is used to measure the force in single-shear
connections in or on machines and equipment of all kinds. Figure 1 shows the typical layout:
Figure 1: Shear force transducer
The shear force transducer consists of a cylindrical or cuboid measuring body(1), which
holds the load to be measured and has features for securing it torsionally and axially (1a), as
well as a connection support ( ), which is permanently connected to the measuring body and
on which - if not placed directly on the measuring body - the necessary elements for the
electrical connection (connector or cable) are attached and which - if not placed in the
measuring body - contains the measuring electronics. The constriction (1b) in the measuring
body for technical measurement reasons can be provided with a filling depending on the
application or optionally on request. Optionally, the measuring body can contain elements to
lubricate the bearing (1c). The measuring body and, if applicable, the connection support are
made of stainless steel.

Figure shows the typical installation conditions:
Figure : Installation conditions
The shear force transducer (1) is connected to the surrounding structure ( ) directly or by
fasteners. Force F transmitted by 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 and/or measuring directions, either with output signals
on separate connectors/cables or combined in one connector/cable, are optionally available.
More information can be found in the technical data sheets, which may be obtained free of
charge from BROSA.

3 Advice on the safe handling of BROSA shea fo ce
t ansduce s
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 sturdy design, BROSA shear force transducers may not be
used for any other than the intended purpose (see. Section .1). Improper use can result in
dangers to the life and limb of the user or third parties and/or impairment of the device in which
the shear force transducer is implemented or other property.
3.1 Handling
WARNING! BROSA sensors contain high-quality measurement electronics. Make sure
they are handled carefully.

- BROSA shear force transducers are delivered in transport-safe packaging. We
recommended that you remove the sensors from the package immediately prior to
installation.
- The mass of the shear force transducer should be taken into account for the selection
of handling and/or lifting devices; it is indicated on the nameplate.
- BROSA shear force transducers must be secured against falling. Do not throw sensors!
- Use as a tool (e.g. striking, 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 at the measurement position: The shear force transducer
should be connected to the surrounding structure directly or with the help of the
intended fasteners.
WARNING! The shear force transducer must not be aligned using impact tools!

After alignment, the shear force transducer must be secured against movement and twisting
with the appropriate elements. Attention must be paid to the correct alignment of the shear
force transducer to the intended measuring direction (see front mark, compare Section . .)
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 connector 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. . .1 Type 0 10 in an intrinsically safe version
The sensors with ExDANGmicro W*** amplifier must be installed according to the following
specifications:

Figure 6: Connection example of sensor Ex i with Ex DANGmirco W*** amplifier
The supply and the measurement signal are guided over isolation amplifiers in the areas
subject to explosion hazards. Isolation amplifiers from other manufacturers can also be used
if they meet the safety-related limit values.
During the installation, the differentiation of the insulation resistance of the strain gauge
resistance bridge versus the spring body sensor must be taken into account. The amplifier
type ExDANGmicro W_A** is to be regarded as separate from the spring body. The amplifier
type ExDANGmicro W_B** is to be regarded as connected to the spring body in case of
error.
The laying of the connection cable with the amplifier type ExDANGmicro W_* B and type
ExDANGmicro W_* B4 requires protection against damage and tensile load, guaranteed by
proper installation.
The complete list of possible amplifier configurations can be found in the certificate.

3.3 Operation and maintenance
3.3.1 Operation
BROSA shear force transducers operate automatically; attaching tools is not required for
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 shear force transducer is installed must be
observed.
BROSA shear force transducers emit neither airborne acoustic noise nor non-ionising
radiation.
Operation of BROSA shear force transducers is permitted only within the parameters and
properties given in the technical data sheets 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 shear force transducer.
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
In its capacity as a sensor, BROSA shear force transducers are maintenance-free. As load-
transmitting elements, however, they are subject to mechanical stress, requiring regular
inspections of the fault-free state of each shear force transducer. 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 soiling
- 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 warranty.
3.4 Disassembly
We recommend performing the following actions in the order given.
a) Ensuring freedom from loads at the measurement position: The shear force
transducer should be unloaded before disassembly.
WARNING! The disassembly of a shear force transducer under load leads to high risks
to life and limb of persons in the vicinity and can cause major damage. This is therefore not
permitted.
b) Undoing the electrical connection
c) Remove the mechanical securing elements
d) Removal of the bearing force transducer
WARNING! If the shear force transducer is to be reused, it must not be removed with
the aid of impact tools!

3.5 Disposal
If the end of the service life is reached, the shear force transducer is to be taken to an
environmentally-friendly disposal facility. Since the non-metallic components constitute a
small part of the mass of the shear force transducer, the rod may be recycled as a whole as
scrap steel. Assignment as stainless steel scrap is preferable.
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 shear force transducers contain traces 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.
