WEEE INFORMATION
“Attuazione della direttiva 2012/19/UE sui
riuti di apparec¬chiature elettriche ed elett-
roniche (RAEE)”
Il simbolo del cassonetto barrato riportato sull’ap-
parecchiatura o sulla sua confezione indica che
il prodotto alla ne della propria vita utile deve
essere raccolto separatamen¬te dagli altri riuti.
La raccolta differenziata della presente ap-pa-
recchiatura giunta a ne vita è organizza¬ta e
gestita dal produttore.
L’utente che desideri disfarsi dell’apparec-chi-
atura dovrà quindi contattare il produt¬tore per
ricevere indicazioni sul sistema da quest’ultimo
adottato per consentire la rac¬colta separata
dell’apparecchiatura giunta a ne vita.
L’adeguata raccolta differenziata per l’avvio
successivo dell’apparecchiatura dismessa al
riciclaggio, al trattamento e allo smaltimento
ambientalmente compatibile contribuisce ad
evitare possibili effetti negativi sull’ambiente e
sulla salute e favorisce il reimpiego e/o riciclo dei
materiali di cui è composta l’ap¬parecchiatura.
“Implementation of Directive 2012/19/EU on
waste electrical and electronic equip¬ment
(WEEE)”
The symbol showing a crossed-out wheeled bin
on equipment or its packaging indicates that the
product must be collected separately from other
waste at the end of its useful life.
The manufacturer is responsible for organ¬ising
and managing the separate collection of this
piece of equipment at the end of its useful life.
Users wishing to dispose of the equipment must
therefore contact the manufacturer to obtain
instructions from the same on how to have the
equipment collected separately at the end of its
useful life.
By collecting the disused equipment sepa¬rately,
it can be recycled, treated or disposed of in an
environmentally friendly manner, thus helping to
prevent the environment and public health from
being affected negatively and enabling reuse
and/or recycling of the materials forming the
same equipment.
„Umsetzung der Richtlinie 2012/19/EU über
Elektro- und Elektronik-Altgeräte (EEA)“
Das Symbol der durchgekreuzten Mülltonne auf
dem Gerät oder der Geräteverpackung weist da-
rauf hin, dass Sie das Produkt am Ende seines
Lebenszyklus separat entsor¬gen müssen.
Die Getrenntsammlung dieses Geräts an seinem
Lebenszyklusende wird vom Her¬steller organi-
siert und besorgt.
Der Nutzer, der das Gerät entsorgen möchte,
muss sich daher an den Hersteller wenden,
um Auskunft über seine Vorgehensweise zur Ge-
trenntsammlung des Geräts an dessen Lebens-
zyklusende zu erhalten.
Die entsprechende Getrenntsammlung für die
anschließende Zuführung des Altgeräts zum
Recycling, zur Wiederaufbereitung und zur
umweltverträglichen Entsorgung trägt dazu bei,
negative Auswirkungen auf die Umwelt und die
Gesundheit zu unterbinden und begünstigt die
Wiederverwendung und/oder das Recycling von
Werkstoffen, aus denen das Gerät besteht.
“Transposition de la Directive 2012/19/UE re-
lative aux déchets d’équipements électriques
et électroniques (RAEE)”
Le pictogramme de la poubelle barrée, gu¬rant
sur l’équipement ou sur son emballage, indique
que le produit en n de vie doit être traité séparé-
ment des autres déchets.
Le ramassage sélectif de cet équipement en n
de vie est organisé et géré par le constructeur.
Tout utilisateur qui souhaiterait se débarras¬ser
de l’équipement devra donc contacter le const-
ructeur pour obtenir des informations concernant
la méthode adoptée pour per¬mettre le ramassa-
ge sélectif de l’équipe¬ment en n de vie.
Un ramassage sélectif correct, en vue de l’ache-
minement de l’équipement vers des opérations
de recyclage, de traitement et de mise au rebut
respectueuses de l’environne-ment, contribue
à réduire les impacts poten-tiellement néfastes
sur l’environnement et la santé, outre à favoriser
la réutilisation des matériaux/composants dont
l’équipement est constitué.

1� GENERAL DESCRIPTION
1�1� GE1029-A
1�2� Function
Main features:
• Direct measurement of surface strain
• With integrated digital amplier
• Quick and easy non-destructive assembly
• High accuracy and linearity in tension and pressure
(like bonded strain gauges)
• Ideal for use on presses, injection-moulding and
die-casting machines
• One system for many different tie bar diameters
(25…250mm)
• Dynamic applications
• Ideal for online monitoring of clamping force
• Ideal for self-made load cells
The strain gauge sensor GE1029-A measure the surface-strain directly at the mounting location in the same quality as
bonded strain gages. The integrated variable digital amplier amplies the signal on the spot, avoiding EMC problems.
The sensor does not have to be recalibrated between remove and re-installation. The press-on technology, developed
by Sensormate AG, presses the strain gauges under the stainless protective lm so strongly against the surface to be
measured that frictional contact occurs.
The sensor is mounted using stainless steel straps, is non-destructive, very fast and simple. For each tie-bar diameter
outside tolerance of ± 2.5mm a different pair of steel straps is required. The sensor can not be overloaded. The
GE1029-A sensors require a cyclic reset.

2� MOUNTING AND INSTALLATION
2�1� Electrical connection
Warning! The installation of the devices described in the manual must be carried out by qua-
lied personnel, following the laws and regulations and in accordance with the instructions
contained in this manual.
Warning! Use extreme caution when installing and xing the sensor unit.
If the sensor unit is installed at a height of more than 1.8 meters, all persons near the moul-
ding machine must wear the protective helmet.
Warning! If even one of the above-mentioned requirements is not met, suspend installation
and contact your Gefran dealer or Gefran Customer Service.

2�2� Mounting
2�2�1� Preparation
2�2�2� Mounting procedure
These sensors are precision instruments. The devices must be handled with the appropriate care.
These instructions must be read and understood by every user.
- Oil and other surface impurities as well as paint must be removed from the place of installation.
- The surface roughness of the place of installation has not to be rougher than N7.
- Check the foil of the sensor GE1029-A for damage.
- The foil of the sensor GE1029-A must be absolutely clean.
1:
There are markings on the stainless steel bands.
(The distance between these markings depends on the diameter of the object to be measured)
2:
The stainless steel strips are xed at the marked position with the individual measuring modules.
(In the following pictures of this chapter the sensor GE1029 is shown.
In the mounting there is no difference to the GE1029-A).

10 / 16 Subject to technical modications
3:
Place the sensor around the object to be
measured and screw it on carefully.
Do not tighten with nal torque yet!
Cables must not be jammed.
4:
Slightly loosen the xing so that the individual
measuring modules can rest perfectly on the
circumference of the measuring object.

11 / 16
Subject to technical modications
5:
The contact points must lie exactly in the axial direction on the surface to be measured.
6:
Screw the sensors hand-tight. Torque = 2 Nm
The two measuring modules must be exactly opposite each other.
The system is now ready to measure.
Torque = 2 Nm
Contact points
Attention:
It is important that the screws are checked with the above torque after the
machine has warmed up or after two days of operation at the latest.
