Specification notes
NOTE 1: The span is the algebraic difference between full scale decimal counts and the offset decimal counts.
Pressure Output Transfer Function:
Where,
Poutdig Is the sensor 14 bit digital output
OSdig Is the specified digital offset (gage = 1,638 and differential = 8,192)
FSS (inH2O) Is the sensor Full Scale Span in inH2O (gage = Full Scale Pressure, differential = 2x Full Scale Pressure)
NOTE 2: Total error band comprises of offset and span temperature and calibration errors, linearity and pressure hysteresis errors, offset warm-up shift, offset position sensitivity and long term offset drift errors.
NOTE 3: Shift is relative to 25°C.
NOTE 4: Shift is within the first hour of excitation applied to the device.
NOTE 5: Parameter is characterized and not 100% tested.
NOTE 6: Measured at one-half full scale rated pressure using best straight line curve fit.
NOTE 7: Temperature output conversion function:
