1
Sensors are either 3.3 Vdc or 5.0 Vdc based on the catalog listing selected.
2
Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage) is achieved within the specified operating voltage.
3
The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure.
4
Operating temperature range: The temperature range over which the sensor will produce an output proportional to pressure.
5
Compensated temperature range: The temperature range over which the sensor will produce an output proportional to pressure within the specified
performance limits.
6
Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the pressure range at 25 °C [77 °F]. Includes
all errors due to pressure non-linearity, pressure hysteresis, and non-repeatability.
7
Orientation sensitivity: The maximum change in offset of the sensor due to a change in position or orientation relative to Earth’s gravitational field.
8
Full Scale Span (FSS): The algebraic difference between the output signal measured at the maximum (Pmax.) and minimum (Pmin.) limits of the pressure range.
(See Figure 4 for ranges.)
