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 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 "Media Compatibility".
