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
sensors were designed for extremely cost
sensitive applications where precise accu-
racy 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 de-
vices allow application of pressure to either
side of the diaphragm and the devices are
thereby available to measure both differen-
tial and/or gage pressures.
This product is packaged either in SenSym's
standard low cost chip carrier "button"
package, a plastic ported "N" 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. These packages can be o-ring
sealed, epoxied, and/or clamped onto a
pressure
fitting.
A

bridge
4-pin SIP configuration is provided for elec-
trical connection to the button package. The
DIP package offer a 5-pin open bridge
configuration.
