Microstructure Pressure Sensors Precision Compensated 0 in H2O to 4 in H2O and 0 in H2O to 10 in H2O SCXL Series

FEATURES

  • Very Low Pressure Resolution
  • Precision Temperature Compensation
  • Small Size
  • Low Noise
  • Calibrated Zero & Span
  • High Impedance for Low Power Applications TYPICAL APPLICATIONS
  • Air Flow
  • Respirators 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 °C to 50 °C [32 °F to 122 °F] temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like.
  • HVAC
  • Medical Equipment
  • Computer Peripherals
  • Pneumatic Controls The output of the bridge is ratiometric to the supply voltage. Operation from any dc supply voltage up to 18 Vdc [Model SCXL004DN] or 20 Vdc [SCXL010DN] is acceptable.

Long Term Stability of Offset and Span (12) – 100 – Microvolts 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: Proof pressure is the pressure above which devices will not return to guaranteed specifications. 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: Zero pressure effect is measured with pins pointed towards the ground. Offset can be position sensitive. 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 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. 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.
