The SCXL series sensors provide a
very cost effective solution for pressure
applications that require high accuracy over
very low operating pressure ranges.
These internally calibrated and
temperature compensated sensors were
specifically designed to provide an accurate
and stable output over a 0癈 to 50癈
temperature range.
This series is intended for use with noncorrosive,
non-ionic working fluids such
as air and dry gases.
The output of the bridge is ratiometric to
the supply voltage and operation from any
D.C. supply voltage up to +18V is
acceptable.

SPECIFICATION NOTES:
1. Reference conditions: Unless otherwise noted: Supply voltage, VS = 12 V, TA = 25癈, 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癈 reading.
5. Maximum difference in output at any pressure with the operating pressure range and temperature within 0癈 to +50癈 after:
a) 100 temperature cycles, 0癈 to 50癈
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 VS = 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.
