ELECTRICAL CONNECTION

The SCX series sensors provide a very cost-effective solution for pressure applications that require operation over wide temperature range. These

internally calibrated and temperature compensated sensors were specifically designed to provide an accurate and stable output over a 0 °C to 70 °C

[32 °F to 158 °F] 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 in model

number) devices have an internal vacuum reference and an output voltage proportional to absolute pressure. The Differential (D in model number) devices allow application of pressure to either side of the pressure-sensing diaphragm and can be used for gage or differential measurements. The SCX series devices feature an integrated circuit (IC) sensor element and laser trimmed thick film ceramic housed in a compact solvent resistant case. This package provides excellent corrosion resistance and provides isolation to external packaging stresses. The package has convenient mounting holes and pressure ports for ease of use with standard plastic tubing for pressure connection.

If the application requires extended temperature range operation, beyond 0 °C to 70 °C [32 °F to 158 °F], two pins which provide an output voltage proportional to temperature are available for use with external circuitry. The 100 microsecond response time makes this series an excellent choice for computer peripherals and pneumatic control applications.

The output of the bridge is ratio metric to the supply voltage. Operation from any dc supply voltage up to 20 Vdc is acceptable.

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.

Maximum pressure above which causes permanent sensor failure. Reference Conditions: (Unless otherwise noted) T

A = 25°C, Supply VS = 12 Vdc, Common Mode Line pressure = 0 psig, Pressure applied toPort B. For absolute devices only, pressure is applied to Port A, and the output polarity is reversed. For models SCX15AN, SCX30AN, SCX100AN, and SCX150AN,

the Maximum zero pressure offset for absolute devices is 0 to ±500 Microvolt.

Pressure Hysteresis – the maximum output difference at any point within the operating pressure range for increasing and decreasing pressure.

Maximum error band of the offset voltage and the error band of the span, relative to the 25 °C [77 °F] reading.

Maximum difference in output at any pressure within the operating pressure range and the temperature within 0 °C to 70 °C [32 °F to 158 °F] after:

a) 1,000 temperature cycles, 0 °C to 70 °C [32 °F to 158 °F] b) 1.5 million pressure cycles, 0 psi to Full-Scale Span. Input resistance is the resistance between pins 2 and 4. Output resistance is the resistance between pins 3 and 5.

Common Mode voltage of the output arms (Pins 3 and 5) for VS=12 Vdc.

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.
