Device is ratiometric within this specified excitation range. Operating the device above the specified excitation range may induce additional error due to device self- -heating. 3. Full Scale Span (V FSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the minimum rated pressure. 4. Offset (Voff) is defined as the output voltage at the minimum rated pressure. 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 maximumoperating temperature points, with zero differential pressure applied.
- Pressure Hysteresis: Output deviation at any pressure within the specified range, when this pressure iscycled 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. 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. 7. Offset stability is the products output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.
Linearity refers to how well a transducers output follows the equation: Vout =V off + sensitivity x P over the operating pressure range. There are two basic methods for calculating nonlinearity: (1) end point straight line fit (see Figure 2) or (2) a least squares best line fit. While a least squares fit gives the best case linearity error (lower numerical value), the calculations required are burdensome. Conversely, an end point fit will give the worst case error (often more desirable in error budget calculations) and the cal- culations are more straightforward for the user. Freescale Semiconductors specified pressure sensor linearities are based on the end point straight line method measured at the midrange pressure. Figure 2.
