Your production can continue 24 hours a
day with SIWAREX U, thanks to the fast
fault diagnostics and replacement of the
module without readjusting the scale.
Each module is already factory-pre-
calibrated.
This obviates the need for time-consuming

operations such as the manual emptying
of containers to readjust the dead weight,
or the positioning of tons of weights to
adjust the scale.

are no tedious settings via DIP switches
