HOW LOAD CELLS WORK
Load cells have an output or sensitivity in mV/V. What this sensitivity/output represents is as follows:
Change in millivolt output
from zero load to the full
scale capacity of the load cell
(21.3 mV in this example)
No load cell has exactly zero millivolts at no load. Most cells have a small millivolt DC offset of a few millivolts
which is normal. To scale a system the end user just scales his recorder/meter for a full scale change of (21.3 mV
per example), and connects the load cell in a no load situation and rezeros the pens/display for a correct zero
reading.
