Accuracy
(5)
(0 °C to 85° C)
5.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 minimum or
maximum rated pressure at 25 °C.
TcSpan: Output deviation over the temperature range of 0 °C to 85 °C, relative to 25 °C.
TcOffset: Output deviation with minimum pressure applied, over the temperature range of 0 °C to 85 °C, relative to 25 °C.
