SCX...C Series Low cost compensated pressure sensors FEATURES · 0...1 to 0...150 psi · Low cost · Precision temperature compensation · Calibrated zero and span · Small size · Low noise · High impedance for low power applications GENERAL DESCRIPTION The SCX...C series sensors will provide a very cost effective solution for pressure applications that require operation over a wide temperature range. These internally calibrated and temperature compensated sensors give an accurate and stable output over a 0°C to 70°C temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases, and the like. Devices are available to measure absolute, differential, and gage pressures from 1 psi (SCX01) up to 150 psi (SCX150). The absolute (A) devices have an internal vacuum reference and an output voltage proportional to absolute pressure. The differential (D) devices allow application of pressure to either side of the pressure sensing diaphragm and can be used for gage or differential pressure measurements. The SCX devices feature an integrated circuit sensor element and laser trimmed thick film ceramic housed in a compact nylon case. This package provides excellent corrosion resistance and provides isolation to external package stresses. The package has convenient mounting holes and pressure ports for ease of use with standard plastic tubing for pressure connection. All SCX devices are calibrated for span to within ±5 % and provide an offset (zero pressure output) of ±1 mV maximum. These parts were designed for low cost applications where the user can typically provide fine adjustment of zero and span in extenal Scale: 1 cm ½ inch APPLICATIONS · Medical Equipment · Computer Peripherals · Pneumatic Control · HVAC circuitry. For higher accuracies, refer to the standard SCX series datasheet. If the application requires extended temperature range operation, beyond 0 to 70°C, two pins which provide an output voltage proportional to temperature are available for use with external circuitry. The output of the bridge is ratiometric to the supply voltage and operation from any D.C. supply voltage up to +20 V is acceptable. Because these devices have very low noise and 100 microsecond response time they are an excellent choice for medical equipment, computer peripherals, and pneumatic control applications.

Reference conditions: Unless otherwise noted: supply voltage, VS = 12 V, TA = 25°C, 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. 2. Maximum pressure above which causes permanent sensor failure. 3. 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. 4. See Definition of Terms. Hysteresis - the maximum output difference at any point within the operating pressure range for increasing and decreasing pressure. 5. Maximum error band of the offset voltage and the error band of the span, relative to the 25°C reading. 6. Maximum difference in output at any pressure with the operating pressure range and temperature within 0°C to +50°C after: a) 1,000 temperature cycles, 0°C to +70°C b) 1.5 million pressure cycles, 0 psi to full-scale span 7. Input impedance is the impedance between pins 2 and 4. 8. Output impedance is the impedance between pins 3 and 5. 9. This is the common-mode voltage of the output arms (pins 3 and 5) for VS = 12 VDC. 10. Response time for a 0 psi to full-scale span pressure step change, 10 % to 90 % rise time. 11.
