1.4 Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
SIWAREX WL200
Operating Instructions, 12/2021, A5E02199611B-13 7

In order to protect plants, systems, machines and networks against cyber threats, it is necessary
to implement – and continuously maintain – a holistic, state-of-the-art industrial security
concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected to
an enterprise network or the internet if and to the extent such a connection is necessary and only
when appropriate security measures (e.g. 󹪝rewalls and/or network segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit
https://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more secure.
Siemens strongly recommends that product updates are applied as soon as they are available
and that the latest product versions are used. Use of product versions that are no longer
supported, and failure to apply the latest updates may increase customer’s exposure to cyber
threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS Feed
under
https://www.siemens.com/industrialsecurity.
1.5 Transportation and storage
To guarantee su󹪟cient protection during transport and storage, observe the following:
• Keep the original packaging for subsequent transportation.
• Devices/replacement parts should be returned in their original packaging.
• If the original packaging is no longer available, ensure that all shipments are properly
packaged to provide su󹪟cient protection during transport. Siemens cannot assume liability
for any costs associated with transportation damages.
NOTICE
Insu󹪟cient protection during storage
The packaging only provides limited protection against moisture and in󹪝ltration.
• Provide additional packaging as necessary.
Special conditions for storage and transportation of the device are listed in Technical data
(Page 49).
1.6 Notes on warranty
The contents of this manual shall not become part of or modify any prior or existing agreement,
commitment or legal relationship. The sales contract contains all obligations on the part of
Siemens as well as the complete and solely applicable warranty conditions. Any statements
regarding device versions described in the manual do not create new warranties or modify the
existing warranty.

Description 3
3.1 Range of application
SIWAREX load cells are used for measuring forces and weights statically and dynamically. You
can use SIWAREX load cells for almost all applications in industrial weighing technology.
Examples include:
• Container weighers, hopper scales or platform scales,
• Roller table, conveyor or crane scales,
• Plants for bottling/packing, dosing and mixing,
• for checking levels and completeness,
• Equipment for monitoring pressing or stretching processes,
• Dynamic scales
All applications can be implemented in equipment requiring o󹪟cial calibration or in areas
subject to explosion hazards.
3.2 Design and principle of operation
Design
SIWAREX load cells are based on strain gauges. Strain-gauge load cells are transducers which
convert mechanical forces into electrical signals. The principle of operation is the same
regardless of variations in design.
'06'06
Figure 3-1 Design, based on the example of an unloaded bending beam load cell
SIWAREX WL200
Operating Instructions, 12/2021, A5E02199611B-13 17

Principle of operation
The basic component in each case is a special type of spring body. The application of force
elastically deforms the spring body. The ohmic resistance of the strain gauges changes as a
result.
F&RPSUHVVHG6*&RPSUHVVHG6*6WUHWFKHG6*6WUHWFKHG6*
Figure 3-2 Principle of operation, based on the example of a loaded bending beam load cell
For each load cell, at least four strain gauges are connected together as a complete Wheatstone
bridge. The stretched or compressed strain gauges are connected in such a manner that the
positive or negative resistance changes are summed to produce an overall imbalance of the
bridge.
The supply voltage is applied across one diagonal of the bridge and, in the case of the six-wire
connection method, also the sensor voltage SENSE. The measured voltage is tapped across the
other diagonal.
For a constant supply voltage EXC, therefore, the measured voltage SIG changes proportionally
to the introduced load. In practice, load cells contain additional resistors for temperature
compensation and for zero-signal and characteristic-value compensation. Depending on their
type and the requirements, these resistors can be arranged at the input or output of the load cell.
