Accuracy
(6)
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 V
FSS
at 25°C.
