Span Sensitivity defines the output signal characteristic of a strain gauge based sensor independent of measurement range or supply voltage.
For example a strain gauge pressure sensor with a span sensitivity of 1 mV/V/bar would have a full span output of 100 mV if connected to a 10Vdc supply and measuring over a range of 10 bar.
