SPECIFICATION NOTES
Note 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.
Note 2: Maximum pressure above which causes permanent sensor failure.
Note 3: Reference Conditions: (Unless otherwise noted)
T
A = 25°C, Supply VS = 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.
Note 4: For models SCX15AN, SCX30AN, SCX100AN, and SCX150AN,
the Maximum zero pressure offset for absolute devices is 0 to ±500 Microvolt.
Note 5: Pressure Hysteresis – the maximum output difference at any point within the operating pressure range for increasing and
decreasing pressure.
Note 6: Maximum error band of the offset voltage and the error band of the span, relative to the 25 °C [77 °F] reading.
Note 7: Maximum difference in output at any pressure within the operating pressure range and the temperature within 0 °C to 70 °C
[32 °F to 158 °F] after:
a) 1,000 temperature cycles, 0 °C to 70 °C [32 °F to 158 °F]
b) 1.5 million pressure cycles, 0 psi to Full-Scale Span.
Note 8: Input resistance is the resistance between pins 2 and 4.
Note 9: Output resistance is the resistance between pins 3 and 5.
Note 10: Common Mode voltage of the output arms (Pins 3 and 5) for VS=12 Vdc.
Note 11: Response time for a 0 psi to Full-Scale Span pressure step change, 10 % to 90 % rise time.
Note 12: Long term stability over a one-year period.
