1. 1.0 kPa (kiloPascal) equals 0.145 psi.
2. Device is ratiometric within this specified excitation range.
3. Offset (V
off
) is defined as the output voltage at the minimum rated pressure.
4. Full Scale Output (V
FSO
) is defined as the output voltage at the maximum or full rated pressure.
5. 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.
6. Accuracy (error budget) consists of 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 10
°
to 60
°
C, relative to 25
°
C.
TcOffset:
Output deviation with minimum rated pressure applied, over the temperature range of 10
°
to 60
°
C, relative to
25
°
C.
Variation from Nominal: The variation from nominal values, for Offset or Full Scale Span, as a percent of V
FSS
, at 25
°
C.
7. Auto Zero at Factory Installation: Due to the sensitivity of the MPXV7002 Series, external mechanical stresses and mounting position can
affect the zero pressure output reading. Autozero is defined as storing the zero pressure output reading and subtracting this from the
device's output during normal operations. Reference AN1636 for specific information. The specified accuracy assumes a maximum
temperature change of ± 5
°
C between autozero and measurement.
8. 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.
9. Warm-up Time is defined as the time required for the product to meet the specified output voltage after the Pressure has been stabilized.
