Hydraulic ring force transducers are designed for measuring static and dynamic
compression forces.They comprise an hydraulic force transducer and a mounted
pressure measuring instrument (pressure gauge, pressure sensor).
The measuring body is manufactured from galvanised steel.The force acting on the
measuring piston is transmitted as pressure, proportional to the piston area, via the fill
fluid in the measuring piston to the pressure measuring instrument.

Applies to the hydraulic ring force transducer with mounted pressure sensor:
The instrument has been designed and tested in accordance with the relevant safety
regulations for electronic measuring instruments. Any usage outside of this is deemed to
be improper. The perfect functioning and operational safety of the force transducers can
only be guaranteed when complying with the instructions given in the operating instruc-
tions. During its use, the legal and safety regulations (e.g.VDE 0100) required for the
particular application must additionally be observed.This also applies accordingly when
using accessories. Faultless and safe operation of this measuring unit requires proper
transport, professional storage, installation and mounting and careful operation and
corrective maintenance.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specifications contained in these operating instructions must be
observed. Improper handling or operation of the instrument outside of its technical
specifications requires the instrument to be taken out of service immediately and
inspected by an authorised service engineer.

WARNING!
Risk of injury should qualification be insufficient
Improper handling can result in considerable injury and damage to
property.
▶
The activities described in these operating instructions may only be
carried out by skilled personnel who have the qualifications described
below.
Skilled electrical personnel
Skilled electrical personnel are understood to be personnel who, based on their
technical training, know-how and experience as well as their knowledge of country-
specific regulations, current standards and directives, are capable of carrying out work
on electrical systems and independently recognising and avoiding potential hazards.
The skilled electrical personnel have been specifically trained for the work environ-
ment they are working in and know the relevant standards and regulations.The skilled
electrical personnel must comply with current legal accident prevention regulations.
3.6 Personal protective equipment
The requirements for the required protective equipment result from the ambient
conditions at the place of use, other products or the connection to other products.
The requisite personal protective equipment must be provided by the operating
company.The operator is in no way relieved of his obligations under labour law for the
safety and the protection of workers' health.
The design of the personal protective equipment must take into account all operating
parameters of the place of use.

4. Transport, packaging and storage
4. Transport, packaging and storage
4.1 Transport
Check the hydraulic ring force transducer for any damage that may have been caused
by transport. Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during
internal transport, proceed carefully and observe the symbols on the
packaging.
▶
With internal transport, observe the instructions in chapter 4.2
“Packaging and storage”.
As precision measuring instruments, hydraulic ring force transducers require careful
handling during transport and mounting. Load impacts during transport (e.g. hitting
a hard surface) can lead to irreversible damage, resulting in measuring errors in the
subsequent measuring operation.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change
in installation site, sending for repair).
The hydraulic ring force transducer has been manufactured from coated steel.
■
The design with pressure gauge fulfils IP65 ingress protection.
■
The design with digital pressure gauge fulfils IP65 ingress protection.
■
The design with pressure sensor fulfils IP67 ingress protection.The design of the
accessory cables fulfils IP67 ingress protection.The ingress protection IP67 is only
guaranteed in the plugged-in state.
During storage the protective cap must always be on the electrical connection to avoid
the ingress of moisture and dirt.
Permissible conditions at the place of storage:
■
Storage temperature: -30 ... +60 °C
■
Humidity: 35 ... 85 % relative humidity (non-condensing)
Avoid exposure to the following factors:
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Dust, dirt, and other objects may not be deposited in such a way that they form a
force shunt with the measuring piston, since this will falsify the measurement.

5.1 Mounting preparation
■
Before mounting the hydraulic ring force transducer, the anchor hole must be drilled,
the anchor positioned, concreted and allowed to harden. For this, a level installation
face must be ensured for the hydraulic ring force transducer.
5.2 Mounting instructions
CAUTION!
Damage to the instrument through improper installation
■
The sealed threaded connections of the hydraulic force transducer
must not be loosened.
■
When installing the hydraulic force transducer, pay attention to the
installation position and thus to the direction of loading.The hydraulic
force transducer must be mounted orthogonally to the anchor.
■
The hydraulic ring force transducer should only be loaded in the
intended position.
■
In the event that, on mounting, the pressure measuring instrument
(pressure gauge, digital pressure gauge or pressure sensor) lies
against the installation face, an anchor plate must be mounted under
the hydraulic ring force transducer.
■
Torsional and transverse forces must be avoided.Transverse loads
and lateral forces also include the corresponding components of the
measurands that are introduced slanted.
■
Torsional moments, eccentric loads and transverse loads or lateral
forces cause measuring errors and may permanently damage the
hydraulic ring force transducer.
■
During installation of the hydraulic ring force transducer, the output
signal or the display instrument (force value) must always be monitored
to avoid mechanical overload.
■
When subjected to loads in other devices, a change in the zero
signal may result in permanent damage (leakage with jamming of the
measuring piston).
■
An overload must be excluded at all times.
■
Do not use the hydraulic ring force transducer as a climbing aid.

5.5 Electrical connection - Hydraulic ring force transducer with pressure sensor
To prevent interferences from coupling into the system, observe the following
information:
■
Use only shielded and low-capacitance measuring cables (for cables, see chapter 10
“Accessories”).
■
Ground the cable shield.
■
In the cables of the accessories, the cable shield is connected by means of the
knurled nut, thus connecting it to the case of the pressure sensor.
■
Do not install measuring cables in parallel to 3-phase-current cables and control
cables.
■
Avoid stray fields of transformers, motors and contactors.
■
Force transducers, amplifiers and processing or display units must not be grounded
several times. Connect all instruments to the same protective conductor.
The pin assignment of the connector or of the cable can be found on the product label.
For an extension, only shielded and low-capacitance cables should be used.The
permitted maximum and minimum lengths of cable are defined in ISO 11898-2. Care
should also be taken with the shielding to ensure a high-quality connection.
