Description
Gravimetric measurement of level with SIWAREX weighing
technology produces
high-precision weight measurement results without any contact with the
material. The weight of your product is correctly determined independently of
the temperature, container shape, material density, shift in the center of
gravity and agitators or the like. Bridging, heaped objects, hopper flow, foam,
steam and dust have no effect on the gravimetric measurement.
These advantages enable SIWAREX weighing technology to be used
in legal-for-trade plants. Measuring points in potentially explosive areas can
be very easily realized with standard components.
We put together the correct load cells and built-in components from our product range for gravimetric
measurement to match the particular application, load range and accuracy
requirements. Our range extends from platform load cells, bending beams and
shear beams to can compression cells in the load classes from 3kg to 280t.
Service-proven load cell technology and separation of the medium
mean maximum service life with no special maintenance. This improves plant availability
and reduces the operating costs on a permanent basis.
The load cell signals are evaluated by SIWAREX weighing
electronics which are seamlessly
integrated in the SIMATIC automation system. This enables very easy handling
and use of the advantages provided by SIMATIC such as flexibility, a diagnostic
interrupt system and much more.
