Table 6: Pressure sensor specifications (part nr.: 2513130810001)
Full Scale Span (FSS) is the algebraic difference between the sensor output at
the maximum and minimum pressure of the measurement range (P
RANGE
).
4. Nonlinearity is the maximum deviation of the sensor output from the straight line fit (BFSL) across the
entire pressure measurement
