Description
Output is proportional to the difference between applied pressure and a built-in vacuum reference.
Output is proportional to the difference between the pressures applied to each port (Port 1 – Port 2).
Output is proportional to the difference between applied pressure and atmospheric (ambient) pressure.

Sensors are either 3.3 Vdc or 5.0 Vdc based on the catalog listing selected.
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. 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
