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.

Response Time(6) (10% to 90%)

6. Response Time is defined as the time from 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.
