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 official 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.
