SPECIFICATION NOTES
Note 1:
Note 2:
Note 3:
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.
Proof pressure is the pressure above which devices will not return to guaranteed specifications.
Reference Conditions: (Unless otherwise noted)
T
A
= 25 °C, 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.
Zero pressure effect is measured with pins pointed towards the ground. Offset can be position sensitive.
Pressure Hysteresis – the maximum output difference at any point within the operating pressure range for increasing and
decreasing pressure.
Maximum error band of the offset voltage and the error band of the span, relative to the 25 °C [77
°F]
reading.
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:
004DN: a) 100 temperature cycles, 0 °C to 50 °C [32
°F
to 122
°F]
b) 1 million pressure cycles, 0 psi to Full-Scale Span.
010DN: a) 1,000 temperature cycles, 0 °C to 50 °C [32
°F
to 122
°F]
b) 1.5 million pressure cycles, 0 psi to Full-Scale Span.
Input resistance is the resistance between pins 2 and 4.
Output resistance is the resistance between pins 3 and 5.
Common Mode voltage of the output arms (Pins 3 and 5) for V
S
=12 Vdc.
Response time for a 0 psi to Full-Scale Span pressure step change, 10 % to 90 % rise time.
Long term stability over a one-year period.
