GENERAL DESCRIPTION
The SX series of pressure sensors
provides the most cost effective
method of measuring pressures up
to 150 psi. These sensors were
specifically designed to be used with
non-corrosive and non-ionic media,
such as air and dry gases. Convenient
pressure ranges are available to
measure differential, gage and
absolute pressures from 0 to 1 psi up
to 0 to 150 psi.
The absolute (A) devices have an in-
ternal vacuum reference and an output
voltage proportional to absolute
pressure. The differential (D) devices
allow application of pressure to either
side of the diaphragm and can be
used for gage or differential pressure
measurements.
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 closed bridge 4-pin SIP configuration
is provided for electrical connection to
the button or "N" package.
Because of its high-impedance
bridge, the SX series is ideal for
portable and low power or battery
opera-ted systems. Due to its low
noise, the SX is an excellent choice
for medical and low pressure
measurements.
