2.1 Overview
2.2 Description
The single point load cell is intended for the measurement of dynamic and static
compression forces in floor and bench scales, multihead combination weighers and
check weighers.The single point load cell consists of a measuring spring on which
strain gauges are applied.The measuring body is made of aluminium and is elastically
deformed by a force introduced in the force direction.The resulting mechanical tensions
are measured by the strain gauges and output as an electrical output signal.
The strain gauges are arranged so that two of them are tensioned and the other two are
compressed when a force is applied to the single point load cell.
The single point load cell circuit includes correction and compensation resistors to
eliminate unwanted effects on the zero signal and characteristic value.

3. Safety
3.3 Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and
injuries.
▶
Refrain from unauthorised modifications to the instrument.
Any use beyond or different to the intended use is considered as improper use.
3.4 Responsibility of the operator
The instrument is used in the industrial sector. The operator is therefore responsible for
legal obligations regarding safety at work.
The safety instructions within these operating instructions, as well as the safety,
accident prevention and environmental protection regulations for the application area
must be maintained.
The operator is obliged to maintain the product label in a legible condition.
To ensure safe working on the instrument, the operating company must ensure:
■
that suitable first-aid equipment is available and aid is provided whenever required.
■
that the skilled electrical personnel are regularly instructed in all topics regarding
work safety, first aid and environmental protection and know the operating
instructions and in particular, the safety instructions contained therein.
■
that the instrument is suitable for the particular application in accordance with its
intended use.
■
that personal protective equipment is available.
Load cells for weighing are designed for use inside buildings.
The load cells are used to measure forces in one direction.The measured force is
output as an electrical signal.These devices are designed for operation in industrial
environment. In other environments, e.g. residential or commercial, they may interfere
with other equipment. In this case the operator may be required to implement
appropriate measures.
Only use the load cells in applications that are within the technical performance limits
(e.g. max. ambient temperature, material compatibility, etc.). For performance limits see
chapter 9 “Specifications”.
The load cells are designed exclusively for the intended use which is described here
and may only be used accordingly.
Claims of any kind due to improper use are excluded.

3. Safety
3.5 Personnel qualification
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 environment
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 single point load cell 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, single point load cells require careful handling
during transport and mounting. Load impacts during transport (e.g. hitting a hard
surface) can lead to permanent 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 measuring spring is manufactured completely from aluminium and corresponds to
IP66 or IP67 ingress protection.
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +65 °C [-4 ... +149°F]
■
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 spring, since this will falsify the measuring signal.
