1 General infor ation
Read the operating instructions and the product-specific documents carefully before
commissioning the sensor.
Make sure that the sensor is fully suitable for the applications in question.
Improper use or any use other than intended may result in a malfunction of the sensor or
undesirable effects in your application. For this reason, installation, electrical connection,
commissioning and maintenance of the sensor may only be carried out by trained personnel
authorized by the plant operator.
We also expressly point out that any liability is excluded if instructions in this documentation
are disregarded.
Current certificates can be downloaded from the BROSA AG website.
Only the German version of this operating manual represents the original document.

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 Label (nameplate, indication of measuring direction)
Each BROSA force measuring pin is equipped with a nameplate containing the respective
information applicable for the given product. Depending on the structural design, it can be
attached either on the front (Figure 3, 1a) or on the long sides (Figure 3, 1b).
Figure 3: Nameplate positions, measuring direction
Figure 4: X-Y FMP measuring direction
The measuring direction is indicated on the front side with an arrow (Figure 3, ). A simplified
indication of the measuring direction (omission of the two lower arrows shown in Figure 3) is
possible.
In the optionally available version with two measuring directions, the measuring directions
are labelled as shown in Figure 4.

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.
