NOTES:
1. 1.0 kPa (kiloPascal) equals 0.145 psi.
2. 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
minimum rated pressure.
) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
FSS
4. Offset (V ) is defined as the output voltage at the minimum rated pressure.
off
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 within the specified range, when this pressure is cycled to and from the
minimum or maximum rated pressure, at 25°C.
Output deviation, after 1000 temperature cycles, – 40 to 125°C, and 1.5 million pressure cycles, with zero
differential pressure applied.
Offset Stability:
•
•
TcSpan:
TcOffset:
Output deviation at full rated pressure over the temperature range of 0 to 85°C, relative to 25°C.
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. Common mode pressures beyond specified may result in leakage at the case–to–lead interface.
8. Exposure beyond these limits may cause permanent damage or degradation to the device.
