2 Description of the BROSA force easuring pin

.1 Structure and functionality

Type 0 01 and 0 03 BROSA force measuring pins are used to measure the force in double

shear connections in or on machines and devices of all kinds.

Fig. 1: Force measuring pin

The force measuring pin consists of a cylindrical measuring body (1), that absorbs the load to

be measured and exhibits the properties for torsional and axial securing (1a) as well as a

connection support ( ) firmly connected to the measuring body in some cases, 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 recess (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 Ex d Type 0 03 force measuring pin is always equipped with a threaded

pin (4) for electrical potential equalisation (optional in the other types). The measuring body

and connection support, if applicable, are made of stainless steel.

The MOP force measuring pin contains integrated mechanical overload protection.

Figure : Installation conditions

The force measuring pin (1) is inserted into the mounting holes ( ) of the double-shear

connection, which have a corresponding diameter, and secured against unintended

movement by means of a pin holder (see Fig. 1, point 1a). 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 directions (X-Y force measuring pin) and/or two measuring

systems, either with output signals on separate connectors/cables or combined in one

plug/cable, are available as options. More information can be found in the technical

datasheets, which can be obtained free of charge from BROSA.

3 Advice on the safe handling of BROSA force easuring

pins

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 force measuring pins may not be used

for any other than the intended purpose (see. Section 1.1). With improper use, dangers to life

and limb of the user or third parties and/or impairment of the device in which the force

measuring pin is implemented or other material assets can be caused.

3.1 Handling

WARNING! BROSA sensors contain high-quality measurement electronics. Make sure

they are handled carefully.

- BROSA force measuring pins are delivered in transport-safe packaging. We

recommended that you remove the sensors from the package immediately prior to

installation.

- The mass of the force measuring pin is to be observed when selecting appropriate

handling equipment and/or lifting gear; it is indicated on the nameplate.

- BROSA force measuring pins 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) Checking 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 force measuring pin is to be

aligned on the intended contact surface according to the offer drawing.

WARNING! The force measuring pin must not be driven in using impact tools!

After alignment, the force measuring pin must be secured against movement and rotation

using the elements provided for this purpose. Attention must be paid to the correct alignment

of the force measuring pin to the intended measuring direction (see front mark, compare

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 force measuring pins 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

relevant requirements for the device in which the force measuring pin is implemented must

be observed.

BROSA force measuring pins emit neither airborne acoustic noise nor non-ionizing radiation.

Operation of BROSA force measuring pins 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 transverse to the measuring

direction are transmitted via the force measuring pin.

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 force measuring pins are maintenance-free. As load-

transmitting elements, however, they are subject to mechanical stress, requiring regular

inspections of the fault-free state of each force measuring pin. The intervals between

inspections depend on the intensity of use and must be determined by the end-user. Additional

lubrication holes are not necessary for the sensor to function, but are used to lubricate

secondary components, so the end-user is responsible for the lubrication cycles.

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) Establishment of a load-free state at the measuring point: The force measuring pin is

to be unloaded before removal.

WARNING! Removal of a force measuring pin under load poses serious dangers to the

life and limb of bystanders and can cause major damage. This is therefore not permitted.

b) Undoing the electrical connection

c) Remove the mechanical securing elements

d) Remove the force measuring pin

WARNING! If the force measuring pin 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 force measuring pin is to be disposed of in an

environmentally friendly way. Since the non-metallic components are a small proportion

compared to the mass of the force measuring pin, it can 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 force measuring pins 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.
