Full Scale Span(3)
3. 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 related pressure.

Linearity(5)
MPX2102D Series
MPX2102A Series
5. Accuracy (error budget) consists of the following:
• Linearity:
Output deviation from a straight line relationship with pressure, using end point method, 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 with the specified range, when this pressure is cycled to and from the minimum
or maximum rated pressure at 25°C.
• TcSpan:
Output deviation at full rated pressure 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.
