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. Non-linearity refers to the Best Straight Line fit, measured for offset pressure, full scale pressure and 1/2 full scale pressure. 4. Error band of the offset voltage, span or bridge impedance in the specified temperature range, relative to the 25C 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 "Media Compatibility".
