| SCXL004DN Precision Compensated, Low Pressure Sensors FEATURES * 0 - 4 In. H 2O * Very Low Pressure Resolution * Precision Temperature Compensation * Low Noise * Calibrated Zero and Span * High Impedance for Low Power Applications GENERAL DESCRIPTION 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 0C to 50C 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.

Reference conditions: Unless otherwise noted: Supply voltage, VS = 12 V, TA = 25C, Common-mode Line Pressure = 0 psig, Pressure Applied to Port B. 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. Zero pressure effect is measured with pins pointed towards the ground. Offset can be position sensitive. Maximum error band of the offset voltage and the error band of the span, relative to the 25C reading. Maximum difference in output at any pressure with the operating pressure range and temperature within 0C to +50C after: a) 100 temperature cycles, 0C to 50C b) 1.0 million pressure cycles, 0 psi to full-scale span Input impedance is the impedance between pins 2 and 4. Output impedance is the impedance between pins 3 and 5. This is the common-mode voltage of the output arms (Pins 3 and 5) for V S = 12 V. 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. Proof pressure is the pressure above which devices will not return to guaranteed specifications. 6. 7. 8. 9. 10. 11.
