WARNING:
Due to the delicate nature of these very
sensitive devices, some special handling is
required. Parts are sensitive to shock and
vibration and must be handled with care.
Dropping on any hard surface (bench top etc.)
can destroy the device. Note 10 In. H O max.

SPECIFICATION NOTES:
1. Reference conditions: Unless otherwise noted: Supply voltage, V_S = 12 V, T_A = 25°C, Common-mode Line Pressure = 0 psig, Pressure Applied to Port B.
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. Zero pressure effect is measured with pins pointed towards the ground. Offset can be position sensitive.
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 output at any pressure with the operating pressure range and temperature within 0°C to +50°C after:
a) 100 temperature cycles, 0°C to 50°C
b) 1.0 million pressure cycles, 0 psi to full-scale span
6. Input impedance is the impedance between pins 2 and 4.
7. Output impedance is the impedance between pins 3 and 5.
8. This is the common-mode voltage of the output arms (Pins 3 and 5) for V_S = 12 V.
9. Response time for a 0 psi 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 pressure above which devices will not return to guaranteed specifications.
