SCX...C Series  
Low cost compensated pressure sensors  
FEATURES  
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-corro-  
sive, non-ionic working fluids such as air,  
dry gases, and the like.  
· 0...1 to 0...150 psi  
· Low cost  
· Precision temperature  
compensation  
· Calibrated zero and span  
· Small size  
Devices are available to measure absolute,  
differential, and gage pressures from 1 psi  
(SCX01) up to 150 psi (SCX150). The ab-  
solute (A) devices have an internal vacuum  
reference and an output voltage proportio-  
nal 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.  
· Low noise  
Scale:  
1 cm  
½ inch  
· High impedance for  
low power applications  
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 pro-  
portional to temperature are available for  
use with external circuitry.  
The SCX devices feature an integrated cir-  
cuit 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 pres-  
sure ports for ease of use with standard  
plastic tubing for pressure connection.  
APPLICATIONS  
· Medical Equipment  
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.  
· Computer Peripherals  
· Pneumatic Control  
· HVAC  
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 applica-  
tions where the user can typically provide  
fine adjustment of zero and span in extenal  
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.
