Notes:
1. Full-Scale Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure.
Full-Scale Span is ratiometric to the supply voltage.
2. Maximum pressure above which causes permanent sensor failure.
3. Reference conditions:
•
T
A
= 25 °C (unless otherwise noted).
• Supply V
S
= 12 Vdc, Common Mode Line pressure = 0 psig.
• Pressure applied to
Port B. For absolute devices only, pressure is applied to Port A and the output polarity is reversed.
4. Maximum zero pressure offset for absolute devices is ±500 mV.
5. Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and decreasing
pressure.
6. Maximum error band of the offset voltage and the error band of the span, relative to the 25 °C [77 °F] reading.
7. Maximum difference in output at any pressure within the operating pressure range and the temperature within 0 °C to 50 °C
[32 °F to 122 °F] after:
• 100 temperature cycles, 0 °C to 50 °C [32 °F to 122 °F].
• 1.0 million pressure cycles, 0 psi to full-scale span.
8. Input resistance is the resistance between V
S
and ground.
9. Output resistance is the resistance between the + and - outputs.
10. Common Mode voltage of the output arms for V
S
=12 Vdc.
11. Response time for a 0 psi to Full-Scale Span pressure step change, 10% to 90% rise time.
12. Long term stability over a one-year period.
13. Maximum combined linearity and hysteresis for the SDX05 prime grade is ±0.5%.
