4S2/S9
Safety instructions
Use in accordance with the regulations
Force transducers in the S2/S9 series are intended for force measurements in
test benches, test rigs and testing devices. Use for any additional purpose
shall be deemed to be not in accordance with the regulations.
In the interests of safety, the transducer should only be operated as described
in the Mounting Instructions. It is also essential to observe the appropriate
legal and safety regulations for the application concerned during use. The
same applies to the use of accessories.
The transducer is not a safety element within the meaning of its use as
intended. Proper and safe operation of this transducer requires proper
transportation, correct storage, assembly and mounting and careful operation
and maintenance.
General dangers due to non-observance of the safety instructions
The S2/S9 force transducer corresponds to the state of the art and is fail-safe.
The transducers can give rise to residual dangers if they are inappropriately
installed and operated by untrained personnel.
Everyone involved with the installation, commissioning, maintenance or repair
of a force transducer must have read and understood the Mounting
Instructions and in particular the technical safety instructions.
Residual dangers
The scope of supply and performance of the transducer covers only a small
area of force measurement technique. In addition, equipment planners,
installers and operators should plan, implement and respond to the safety
engineering considerations of force measurement technique in such a way as
to minimise residual dangers. Prevailing regulations must be complied with at
all times. There must be reference to the residual dangers connected with
force measurement technique.

2 Application notes
Force transducers in the S2/S9 Series are suitable for measuring tensile and
compressive forces. They provide extremely accurate measurements of static
and dynamic forces and must therefore be handled carefully. You must take
particular care when transporting and installing the devices. Transducers can
be permanently damaged if jolted or dropped.
The perfect seal (sealant) intended to protect sensitive strain gauge
applications must be maintained under all conditions.
The sealant must not be damaged.
The permissible limits for mechanical, thermal and electrical stresses are
stated in the Specifications. Please take these points into account whenever
planning measurement arrangements and when installing or operating the
equipment.

8S2/S9
3 Structure and mode of operation
3.1 Measuring element
The measuring device is a flexible aluminium/steel bar to which strain gauges
(SGs) are applied. The SGs are arranged so that four of them are stretched
and the other four are compressed when a force is applied to the transducer.
3.2 Strain gauge cover
To protect the strain gauges, S2/S9 force transducers are sealed with a plastic
compound at appropriate points. This seal must be protected from mechanical
damage.

4 Conditions on site
4.1 Ambient temperature
The effects of temperature on the zero signal and sensitivity are
compensated. For optimum measurement results, keep to the nominal
temperature range. Measurement errors due to temperature may occur if
there is uneven warming (e.g. by radiant heat) or cooling. Whilst a radiation
shield and all-round heat insulation provide noticeable improvements, they
should not be permitted to create any kind of force leakage.
4.2 Moisture
Extremes of humidity or tropical conditions are to be avoided where outside
the specified limit values (degree of protection IP65 to DIN EN 60529).
4.3 Contamination
Dust, dirt and other foreign bodies should not be allowed to accumulate to
such an extent that part of the measuring force can be diverted onto the
housing and falsify the measured value (force leakage).
NOTE:
The gap under the force introduction parts must not become
clogged with foreign bodies.

10 S2/S9
5 Mechanical installation
5.1 Important measures for installation
•Treat the transducer gently
•Do not overload the transducer.
WARNING
If there is a risk of breakage through overload on the transducer
and thus a risk to persons, additional safety measures are to be
taken.
5.2 General installation guidelines
Forces to be measured must as far as possible act on the transducer
precisely in the direction of measurement. Torsion and bending moments,
eccentric loading and transverse forces may result in measurement errors and
if the limit values are exceeded could destroy the transducer.
HBM supplies knuckle eyes for series S2/S9 transducers as mounting
accessories. Knuckle eyes are suitable for use in the event of quasi-static
loading (stress reversal v10Hz). When there is dynamic loading at a higher
frequency, flexible tension bars should be used.
Knuckle eyes prevent torsional moments from being introduced into the
transducer. If two knuckle eyes are used, these have the further effect of
excluding bending moments, as well as lateral and oblique loadings.
NOTE:
The cable-mounting side of the transducer should always be
connected directly to the rigid force outlet sections customer-side.
When doing so, make sure as far as possible that the position of
the cable causes no force leakage (for instance due to its weight
or stiffness).

S2/S9
5.3 Installation for tensile loading/compressive loading
Screw the transducer by its flange or base directly to an available part of the
structure (such as a profile, cover or plate). This method enables the
transducer to measure axial forces in both the tensile and compressive
direction. Alternating loads can also be covered with very little effort. Make
sure the transducer is installed without any axial play. For dynamic and
sustained loading, use lock nuts to pre-tension the upper and lower threaded
connectors to a value exceeding the maximum load.
5.3.1 Installation using two knuckle eyes
If the transducer is going to be subjected to tensile loading, it can be installed
using knuckle eyes.

14 S2/S9
6 Electrical connection
The transducers are supplied with a 3m (S2) or 6 m (S9) length of
unterminated cable.
ATTENTION
The balancing resistors must not be cut off the end of the cable
(sensitivity would alter).
The cable shielding is connected in accordance with the Greenline concept.
Under this scheme, the measurement system is enclosed in a Faraday cage;
then electromagnetic interference does not affect the measurement system.
Transducers with unterminated cables must be fitted with connectors to CE
standard. In this event the shielding must be laid evenly over the whole area.
If a different connection technique is used then good EMC shielding is to be
provided in the wiring loom, the shielding again being laid over the full area
(see also HBM Greenline Information, document G36.35.0).
6.1 Notes on cabling
•Always use shielded, low-capacitance measurement cable supplied by
HBM.
•Do not lay measurement cable parallel to high-voltage power lines or
control circuits. If this is not possible (e.g. in cable shafts) protect the
measurement cable, e.g. with armoured steel tube and maintain a minimum
distance of 50 cm from the other cables. High-voltage power lines and
control circuits should be twisted (15 turns per metre).
•Avoid stray fields from transformers, motors and contactors.
•Do not earth transducer, amplifier and display device more than once. All
the devices in the measurement chain are to be connected to the same
earthed conductor.
•Link the connection cable shielding to the transducer housing.

S2/S9
The sensitivity of the transducer changes when operating in four-wire
connection. The change in the thermal coefficient of sensitivity (TKC) is
negligibly small. Changing the cable length changes the sensitivity.
There is no correction for the effects of temperature on the cable.
