Specification notes:
1.
The maximum specified pressure which may be applied to the sensor without causing a permanent change in the output
characteristics.
2.
Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure. Span is
ratiometric to the supply voltage.
3.
Linearity (BSL), the deviation of measured output at constant temperature (25°C) from "Best Straight Line" determined by three
points, offset pressure, full-scale pressure and half full-scale pressure.

where: V = measured value for each device
4.
Error band of the offset voltage, and span in the specified temperature range, relative to the 25°C reading.
5.
Repeatability, the deviation in output readings for successive application of any given input pressure (all other conditions
remaining constant. Hysteresis, the error defined by the deviation in output signal obtained when a specific pressure point is
approached first with increasing pressure, then with decreasing pressure or vice versa (all other conditions remaining constant).
6.
Response time for 0 to full-scale pressure step change, readings taken at 10 % and 90 % of full-scale pressure.
7.
Long term stability of offset and span over a period over one year.
8.
The sensors might be used on both ports, for media compatible with the components, specified under "Service" (page 1).
