Reference conditions: supply voltage, VS=12 VDC; TA=25 °C; RH=50 %; common mode line pressure = 0 bar; pressure applied to high pressure port. 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. Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and decreasing pressure. 4. Maximum error band of the offset voltage and the error band of the span, relative to the 25°C reading. 5. Maximum difference in offset respectively maximum difference in span within the temperature range of 0...+50°C after: a) 100 temperature cycles, 0...+50°C. b) 1.0 million pressure cycles, 0 psi to full scale span. 6. Input impedance is the impedance between VS and ground. 7. Output impedance is the impedance between + and - outputs. 8. This is the common mode voltage of the output arms for VS = 12 VDC. 9. Response time for a zero to full scale span pressure step change, 10 to 90 % rise time. 10. Long term stability over a one year period. 11. Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters of the sensing element. 12. Burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks to the housing.
