Note:
1.Accuracy is the deviation in actual output from nominal output over the entire pressure range and temperature range as a percent of span at 25°C due to all sources of error including 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 the 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 rated 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.
2. Offset (Voff) is defined as the output voltage at the minimum rated pressure.
3. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure.
4. 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.
