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 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 pressure applied, over the temperature range of 10

° to 60°C, relative to 25°C.

5. Auto Zero at Factory Installation: Due to the sensitivity of the MPXV4006, external mechanical stresses and mounting position can affect the

zero pressure output reading. To obtain the 2.46% FSS accuracy, the device output must be “autozeroed'' after installation. Autozeroing is

defined as storing the zero pressure output reading and subtracting this from the device's output during normal operations. The specified

accuracy assumes a maximum temperature change of ±5

°C between autozero and measurement.
