CALIBRATION
OF INDUSTRIAL PROCESS WEIGHING SYSTEMS
DESCRIPTION
More recent technological advancements
have resulted in digitally summed systems that operate somewhat
differently. In a digitally summed
system, the individual load cell output is digitized, therefore providing a
known or calibrated measurement of each vessel support point. This digitization
can take place in either the load cell itself, or in a separate transmitter
device. The output of each transducer is communicated on a simple local area
network to a display or re-transmission device where the digital values are
added or summed together.
