Safety note

Use for intended purpose

The force transducers in model series F5301 are intended for the
measurement of static and dynamic tensile or compressive force.
These devices have been constructed and tested in accordance with
the safety regulations for electronic measuring equipment.
Any other usage is deemed to be incorrect . The transducers can only
be guaranteed to operate correctly and safely if the information in the
operating instructions is complied with. The legal and safety
regulations that apply to the respective application must also be
observed during use (e.g. VDE 0100). This also applies to the use of
accessories.
The transducer is not intended to be used a safety element.
The correct and safe operation of this transducer depends on correct
transportation and proper storage, installation and assembly and
careful operation and maintenance.

General dangers if the safety instructions are not followed

Force transducers made by tecsis are manufactured in accordance
with the latest state of technology and are safe during operation.
However, the transducers can be the source of residual danger
are used or operated improperly.
Any person who is entrusted to install, start up, maintain or repair a
force transducer must have read and understood the operating
instructions, particularly the technical safety instructions.

Residual dangers

The performance and scope of delivery of the transducer only cover a
sub-area of force measuring technology. The technical safety aspects
of force measuring technology must also be planned and implemented
by the system planner / equipper / operator in such a way that residual
dangers are minimised. The existing regulations must be complied
with. Residual dangers associated with force measuring technology
must be pointed out.

Maintenance

The force transducers in the F5301 model series are maintenance­free.
During welding work the transducer must be bypassed with a copper

2

wire (min. 50 mm

) so that welding current does not flow through the

transducer and weld the force introduction points.

Ambient temperature

The temperature range of -20°C to +80°C that is specified in the data
sheet applies with regard to deployment. The specified error limits are
not guaranteed outside this temperature range.

Moisture and corrosion protection

Tropical climates and condensation are not a problem because the
transducers comply with protection class IP 67 in accordance with
EN 60529:1991+A1:2000 / IEC 529.

Deposits

Dust, dirt and other object must not be allowed to form deposits in
such a way that they create a force short-circuit to the measuring
spring, which would falsify the measuring signal.

Precautions to take during assembly

• Force measuring equipment is extremely sensitive and must be
handled carefully.

• Attention must be paid to the installation position and therefore the
load direction when the force transducers are being installed.

• The transverse loads and side forces also include the relevant
components of the measured variables, which may be introduced at
an incline.

• Care must therefore be taken to keep the transducer free of lateral
loads and torsion during assembly (e.g. when tightening the lock
nuts).

• Overloading must be prevented at all times.

• The output signal (c=1-2mV/V, 4...20mA, 0…20mA, 0...10V) is noted

on the name plate (Fig. 1). The connection assignments are also
noted on the name plate and can also be found in the section entitled
“Electrical connection”. The polarity must be correct at all times.

5301 Series Load Pins

General Installation Guidelines

• The loads acting upon the force transducer must be as exact as
possible in the load direction.

• Torsion and lateral force must be avoided. The transverse loads and
side forces also include the relevant components of the measured
variables, which may be introduced at an incline.

• Torsional moments, off-centre loads and lateral loads or side forces
cause measuring errors and can permanently damage the
transducers.

• The axle bracket grooves also serve as a reference for aligning the
measuring axle.

• The DIN 15 058 axle bracket must be attached in such a way that the
measuring axle is prevented from twisting in the bearing and does
not have any axial play.

The measuring axle may only be subjected to load if the correct type of

•

bearing has been used. Loads occurring in other equipment may change
the zero signal and result in permanent damage.

The introduction of force in the centre must not wander and must be

•

installed in such a way that axial shifts are prevented. However, force by­passing may not occur.

Please note the following:

• Always use shielded, low-capacity measuring cables
(all tecsis cables meet these requirements, see chapter 10.1).

• Do not route the measuring cable parallel to high-voltage current and
control cables.

• Avoid leakage fields from transformers, motors and contactors.

• The transducer, the amplifier and the display unit must not have

multiple grounds. Attach all equipment to the same protective
conductor.

This well proven design has been amended by an additional resistor R7
in order to monitor the condition of the amplifier unit and signal path.
This resistor is connected as a shunt to resistor R5 by a relay contact
(a) as soon as an excitation voltage U

appears at relay A.

The connection of resistor R7 will always result in a defined unbalancing
of the zero point (diagonal voltage) of the Wheatstone Bridge.
An external independent control unit activates relay A which changes
the output by a certain value. Because of security reasons the control
unit has to be a 2-channel one. When the expected change of the
output signal is detected it can be assumed that the whole signal path
(Wheatstone Bridge – amplifier – output) works well.
If it does not appear it can be concluded that there is a defect in the
signal path.

The standard adjustment of force transducers with current output for
overload control is e.g.:

With activating the check relay a fixed signal jump of 8 mA will exceed

the overload limit in every working condition. The measurement’s upper

limit of 20 mA however will never be reached. This makes the checking
of the signal jump possible.
