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 rated pressure.

Linearity(5)
MPXM2202D/G Series
MPXM2202A 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.
• 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.
• 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.
• 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.

specified step change in pressure.
