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.

• 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.
