4. 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.
Offset Stability:Output deviation, after 1000 temperature cycles, -30 to 100°C, and 1.5 million pressure cycles, with minimum rated pressure
applied.
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.
5. Auto Zero at Factory Installation: Due to the sensitivity of the MPVZ5004G, external mechanical stresses and mounting position can affect
the zero pressure output reading. Autozeroing 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.
