SPECIFICATION NOTES

1)

The digital pressure output signal is not ratiometric to the supply voltage.

2)

The pressure ranges with specified minimum and maximum pressure are listed in Table 1.

3)

The Full Span Output (FSO) is the algebraic difference between the output signal at the specified maximum

pressure and the output signal at the specified minimum pressure (see Table 1).

4)

The digital temperature output signal is not ratiometric to the supply voltage. The temperature output value is the

overall sensor temperature

. It is measured at the sensor’s signal conditioning ASIC and is influenced by the

measurement media’s temperature, the ambient temperature, the sensor’s self-heating and the thermal

conductivity of the material in contact to the sensor (e.g. PCB, mounting assembly, pressure hoses).

5)

Accuracy is defined as the maximum deviation of the measurement value from the ideal characteristic curve at

room temperature (RT) in %FSO including the adjustment error (offset and span), nonlinearity, pressure

hysteresis and repeatability. Nonlinearity is the measured deviation from the best fit straight line (BFSL) across

the entire pressure range. Pressure hysteresis is the maximum deviation of the output value at any pressure

within the specified range when the pressure is cycled to and from the minimum or maximum rated pressure.

Repeatability is the maximum deviation of the output value at any pressure within the specified range after

10 pressure cycles.

6)

The TEB (total error band or overall error) is defined as the maximum deviation of the measurement value from

the ideal characteristic curve in %FSO across the entire temperature range.

7)

Media compatibility of pressure port 1 (for a description of port 1 see Figure 5): fluids and gases non-corrosive to

LCP, silicon, Pyrex, RTV silicone rubber and epoxy.

8)

Media compatibility of pressure port 2 (for a description of port 2 see Figure 5): clean, dry gases, non-corrosive to

LCP, silicon, RTV silicone rubber, epoxy, gold (alkaline or acidic liquids can destroy the sensor).
