TYPICAL APPLICATIONS

• Medical Equipment

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.

• Barometry

• Computer Peripherals

• Pneumatic Controls

• HVAC

ELECTRICAL CONNECTION

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.

PIN 1) TEMPERATURE OUTPUT (+)

PIN 2) Vs

PIN 3) + OUTPUT

PIN 4) GROUND

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.

PIN 5) - OUTPUT

PIN 6) TEMPERATURE OUTPUT (-)

Note: The polarity indicated is for

pressure applied to port B. (For

absolute devices pressure is applied

to port A and the output polarity is

reversed)

The output of the bridge is ratio metric to the supply voltage. Operation from

any dc supply voltage up to 20 Vdc is acceptable.

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: Maximum pressure above which causes permanent sensor failure.

Note 3: Reference Conditions: (Unless otherwise noted)

= 25°C, Supply V

= 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: For models SCX15AN, SCX30AN, SCX100AN, and SCX150AN,

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

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 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.

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 V

=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.
