Figure 2.1 is an example of a typical resistive bridge sensor with no applied stimulus. With no stimulus applied, the
resistors ideally would be perfectly matched and the sensors’output (V
IN_DIF
) would be zero. Most practical sensors,
however, will have some output resulting from resistor mismatch.The output signal with no applied stimulus is called
offset. Figure 2.2 is an example of a typical resistive bridge sensor with full scale stimulus applied. For the example sensor,
the offset is 5mV (Figure 2.1) and the full scale output is 32mV(Figure 2.2). Span is defined as the difference between the
full scale stimulus and the offset (Span = Full Scale Output –Offset).
