Technical Description
1.1
Area of Application
SIWAREX R load cells are used for static and dynamic measurements of forces
and weights. They can be used for almost all applications in industrial weighing
technology. These may be for example:
•
container, hopper or platform scales,
•
rollway, belt or crane scales,
•
filling/packing plants, proportioning and mixing,
•
filling level and completeness inspection,
•
equipment for monitoring pressing and clamping procedures,
•
dynamic scales
All applications can be located in areas with mandatory calibration or in hazardous
areas.
1.2
Structure
The SIWAREX R load cells are equipped with wire strain gauges (WSG). WSG
load cells are transducers for converting mechanical forces into electrical signals.
The functional principle is always the same despite different designs.
The basic element is a special spring body. The spring body is deformed elastically
when a force is applied. The integrated WSGs then change their ohmic resistance
