The analog transducer signal is first amplified, then ana
log filtered, and digitized in the A/D converter. This signal
is processed in the microprocessor and can be transmit
ted over the interface. Digital inputs/outputs are available
for control. The electronics have various programs for
applications such as filling, dosing, checkweighers or
weight grading machines. All the parameters can be
stored power failsafe.
