Specification notes:
1.
The maximum specified force 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 force and the output at zero force. 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.
4.
Error band of the offset voltage, span or bridge impedance 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 force (all other conditions
remaining constant. Hysteresis, the error defined by the deviation in output signal obtained when a specific force point is
approached first with increasing force, then with decreasing force or vice versa (all other conditions remaining constant).
