SCC SERIES
Pressure Sensors
FEATURES
GENERAL DESCRIPTION
The SCC series offer an extremely low
cost sensor element with a temperature
stable output when driven with a constant
current source. These integrated circuit
sen-sors were designed for extremely cost
sensitive applications where precise
accuracy over a wide temperature range
is not required. This series is intended for
use with non-corrosive, non-ionic working
fluids such as air and dry gases.
Absolute devices have an internal vacuum
reference and an output voltage proportio-
nal to applied pressure. The differential
devices allow application of pressure to
either side of the diaphragm and the devices
are thereby available to measure both dif-
ferential and/or gage pressures.

This product is packaged either in
SenSym´s standard low cost chip carrier
"button" package, a plastic ported "N"
package, a metal package or a dual inline
package (DIP). All packages are designed
for applications where the sensing element
is to be integral to the OEM equipment. The-
se packages can be O-ring sealed, epoxied,
and/or clamped onto a pressure fitting. A
closed bridge four-pin SIP configuration is
· Automotive Diagnostics
· Medical Equipment
· Dental Equipment
provided for electrical connection to the
button package. The TO can and the DIP
offer a 5-pin open bridge configuration.
· Environmental Controls
