SBOU024C august 2004 – july 2023 PGA309
The focus of this section is to define the design equations used to scale the PGA309 when using the Linearization Circuit.
Nonlinear Pressure Conversion for Bridge Sensor Parabolic Nonlinearity:
BV = positive for a positive parabolic nonlinearity,
BV = negative for a negative parabolic nonlinearity; see Figure 2-13)
Pressure Constant (PNL referenced to full-scale input pressure):
where Full-Scale Ratio = 0.166 (Range 0) or 0.124 (Range 1)
