NOTES:
1. 1.0kPa (kiloPascal) equals 0.145 psi.
2. Device is ratiometric within this specified excitation range.
3. Offset (Voff) is defined as the output voltage at the minimum rated pressure.
4. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure.
5. Full Scale Span (VFSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
minimum rated pressure.
6. Accuracy (error budget) consists of the following:
Linearity:
Output deviation from a straight line relationship with pressure over the specified pressure range.
Temperature Hysteresis: Output deviation at any temperature within the operating temperature range, after the temperature is
cycled to and from the minimum or maximum operating temperature points, with zero differential pressure
applied.
Pressure Hysteresis:
Output deviation at any pressure within the specified range, when this pressure is cycled to and from
minimum or maximum rated pressure at 25
°
C.
TcSpan:
Output deviation over the temperature range of 0
°
to 85
°
C, relative to 25
°
C.
TcOffset:
Output deviation with minimum pressure applied, over the temperature range of 0
°
to 85
°
C, relative
to 25
°
C.
Variation from Nominal:
The variation from nominal values, for Offset or Full Scale Span, as a percent of VFSS at 25
°
C.
