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 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.

6. Response Time is defined as the time for the incremental change in the output to go from 10% to 90% of its final value when subjected to a

specified step change in pressure.
