1 Safety instructions
Designated use
The force transducers in the type series S2M are solely
designed for measuring static and dynamic tensile and/or
compressive forces within the load limits specified by the
technical data for the respective maximum capacities.
Any other use is not the designated use.
To ensure safe operation, the regulations in the mounting
and operating instructions, together with the following
safety rules and regulations, and the data specified in the
technical data sheets, must be complied with. It is also
essential to observe the applicable legal and safety regu
lations for the application concerned.
The force transducers are not intended for use as safety
components. Please also refer to the section: “Additional
safety precautions". Proper and safe operation of force
transducers requires proper transportation, correct stor
age, siting and mounting, and careful operation.
Loading capacity limits
The data in the technical data sheet must be complied
with when using the force transducer. In particular, the
respective maximum loads specified must never be
exceeded. The following limits set out in the technical
data sheets must not be exceeded
SLimit loads
SLateral load limits
SBreaking loads
SPermissible dynamic loads
STemperature limits

Safety instructions
S2M A3592-1.3 HBM: public 5
SLimits of electrical loading capacity
Please note that when several force transducers are
interconnected, the load /force distribution is not always
uniform.
Use as a machine element
The force transducers can be used as machine ele
ments. When used in this manner, it must be noted that,
to favor greater sensitivity, the force transducer was not
designed with the safety factors usual in mechanical
engineering. Please refer here to the section “Loading
capacity limits" and to the specifications.
Accident prevention
The prevailing accident prevention regulations must be
taken into account, even though the nominal (rated) force
values in the destructive range are well in excess of the
full scale value.
Additional safety precautions
The force transducers cannot (as passive transducers)
implement any (safety‐relevant) cutoffs. This requires
additional components and constructive measures for
which the installer and operator of the plant is respons
ible.
In cases where a breakage or malfunction of the force
transducer would cause injury to persons or damage to
equipment, the user must take appropriate additional
safety precautions that meet at least the requirements of
applicable safety and accident prevention regulations
(e.g. automatic emergency shutdown, overload protec
tion, catch straps or chains, or other fall protection).

Safety instructions
6A3592-1.3 HBM: public S2M
The layout of the electronics conditioning the measure
ment signal should be such that measurement signal fail
ure does not cause damage.
General dangers of failing to follow the safety
instructions
The force transducers are state‐of‐the‐art and reliable.
There may be risks involved if the transducers are moun
ted, sited, installed and operated inappropriately, or by
untrained personnel. Every person involved with siting,
starting‐up, operating or repairing a force transducer
must have read and understood the mounting instruc
tions and in particular the technical safety instructions.
The force transducers can be damaged or destroyed by
non‐designated use of the force transducer or by
non‐compliance with the mounting and operating instruc
tions, these safety instructions or any other applicable
safety regulations (BG safety and accident prevention
regulations) when using the force transducers. Force
transducers can break, particularly in the case of over
loading. The breakage of a force transducer can also
cause damage to property or injury to persons in the
vicinity of the force transducer.
If force transducers are not used according to their desig
nated use, or if the safety instructions or specifications in
the mounting and operating instructions are ignored, it is
also possible that the force transducer may fail or mal
function, with the result that persons or property may be
affected (due to the loads acting on or being monitored
by the force transducer).
The scope of supply and performance of the transducer
covers only a small area of force measurement techno
logy, as measurements with (resistive) strain gauge
sensors presuppose the use of electronic signal condi
tioning. In addition, equipment planners, installers and

Safety instructions
S2M A3592-1.3 HBM: public 7
operators should plan, implement and respond to the
safety engineering considerations of force measurement
technology in such a way as to minimize residual
dangers. On‐site regulations must be complied with at all
times.

ber 1-U1R/200KG/ZGW
Equipment variants
All force transducers are available in the following ver
sions:
1. Cables
The standard version of the S2M is equipped with a
6 m long cable. You can also order the force trans
ducer with the following cable lengths:
- 1.5 m (option 01M5)
- 3 m (option 03M0)
2. Plugs
We can fit one of the following plugs to the S2M on
request:
- D-SUB connector, 15-pin: a 15-pin plug for connec
tion to numerous amplifier systems, e.g. MGCplus,
Scout, MP85, etc. (option F)
- D-SUB HD connector: a 15-pin plug for connection
to appropriate amplifier systems, e.g. the HBM
QuantumX system (option Q)

Scope of supply and equipment variants
S2M A3592-1.3 HBM: public 11
- 3106 PEMV connector (Greenline): for connection
to appropriate amplifier systems, e.g. MGCplus
with AP03. (option N)
- ConP1016 connector, 14-pin, for connection to the
Somat XR measurement system.
- Free ends: transducer delivered without plugs
3. TEDS
You can order the force transducer with transducer
identification ("TEDS"). TEDS (Transducer Electronic
Data Sheet) allows you to store the transducer data
(characteristic values) in a chip that can be read out
by a connected measuring device (with an appropriate
amplifier). HBM records the TEDS data before deliv
ery so that no parameterization of the amplifier is ne
cessary. TEDS can only be fitted in the plug of the
S2M, therefore it is not possible to equip the "free
cable ends" version with TEDS

General application instructions
12 A3592-1.3 HBM: public S2M
3 General application instructions
The S2M type series force transducers are suitable for
measuring tensile and compressive forces. Because they
provide highly accurate static and dynamic force meas
urements, they must be handled very carefully. Particular
care must be taken when transporting and installing the
devices. Dropping or knocking the transducer may cause
permanent damage.
The potting material (sealing for protection of sensitive
strain gauge installations) must not be damaged, other
wise the transducer will become unusable.
The specifications list the permissible limits for mechan
ical, thermal and electrical stress. It is essential that
these are taken into account when planning the measur
ing set‐up, during installation and, ultimately, during oper
ation.

Structure and mode of operation
S2M A3592-1.3 HBM: public 13
4 Structure and mode of operation
4.1 Measuring body
The measuring body is an aluminum bending beam on
which strain gauges (SG) are installed. The SG are
arranged so that two are stretched and the other two
compressed when a force acts on the transducer.
4.2 Strain gauge covering agent
To protect the SG, the S2M force transducers are potted
with a plastic material at an appropriate place. This pro
cedure offers the SG high protection against environ
mental influences. To retain the protective capacity and
ensure permanent functionality, the force transducer pot
ting material must not become damaged.

4.3 Disturbance variables
Torsion, bending and lateral loads are disturbance vari
ables and therefore to be avoided.

Conditions on site
14 A3592-1.3 HBM: public S2M
5 Conditions on site
Protect the transducer from weather conditions such as
rain, snow, ice and salt water.
5.1 Ambient temperature
The temperature effects on the zero signal and on the
sensitivity are compensated.
To obtain optimum measurement results, the nominal
(rated) temperature range must be observed. Constant,
or very slowly changing temperatures are optimal. Tem
perature‐related measurement errors are caused by
heating on one side (e.g. radiant heat) or by cooling. A
radiation shield and all‐round thermal insulation produce
noticeable improvements, but must not be allowed to set
up a force shunt.
5.2 Moisture and humidity
Series S2M force transducers are protected against
moisture. The transducers attain protection class IP67
per DIN EN60259. Despite this, force transducers must
be protected against permanent exposure to moisture.
The transducer must be protected against chemicals that
could attack the aluminum, potting material or the cable.
The transducer can also malfunction due to corrosion.
Implement some means of protection if this danger
exists.

Conditions on site
S2M A3592-1.3 HBM: public 15
Notice
Moisture must not be allowed to penetrate the free end of
the connection cable. Otherwise the characteristic values
of the transducer could vary, and cause measurement
errors.
5.3 Deposits
Dust, dirt and other foreign matter must not be allowed to
accumulate sufficiently to divert some of the force to be
measured, thus invalidating the measured value (force
shunt).
Notice
Measurement errors may be the result if dust or dirt is
deposited inside the load cells. The relevant areas are
marked by arrows in Fig. 5.1.
The overload stop must
remain free
Fig. 5.1 Deposits at the marked areas must be avoided

6.1 Important precautions during
installation
SHandle the transducer with care.
SWelding currents must not be allowed to flow over the
transducer. If there is a risk that this might happen,
you must use a suitable low‐ohm connection to elec
trically bypass the transducer. HBM, for example,
provides the highly flexible EEK ground cable, which
can be screwed on above and below the transducer.
SMake sure that the transducer cannot be overloaded.
WARNING
There is a danger of the transducer breaking if it is over
loaded. This can cause danger for the operating person
nel of the system in which the transducer is installed.
Implement appropriate safety measures to avoid over
loads or to protect against the resulting dangers.
6.2 General installation guidelines
The forces to be measured must act on the transducer
as accurately as possible in the direction of measure
ment. Torsional and bending moments, eccentric load
ings and lateral forces can produce measurement errors
and can destroy the transducer if limit values are
exceeded. Interference effects must be absorbed by suit
able construction elements, whereby these elements

Mechanical installation
S2M A3592-1.3 HBM: public 17
must not absorb any forces in the measuring direction of
the transducer. Screws, knuckle eyes and other cus
tomer‐side construction elements must be screwed into
the S2M in such a way that the construction element
does not touch the measuring body (potting material)
even at full displacement.
Notice
Do not loosen the hexagon socket screws (Allen screws)
that connect the force applications and the overload stop
with the measuring body, as otherwise the force trans
ducer calibration could become invalid.

Important
The cable fastening side of the transducer should always
be connected directly with the rigid customer‐side force
transfer areas. Ensure that the cable is laid so that,
where possible, no force shunt is caused by the cable
(e.g. through the weight or stiffness of the cable), see
Fig. 6.1.
