GENERAL DESCRIPTION
The SX Series of pressure sensors
provide 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 (SX01) up to 0 to
300 psi (SX7300D).
The Absolute (A) devices have an internal
vacuum reference and an output voltage
proportional to absolute pressure. The Dif-
ferential (D) devices allow application of
pressure to either side of the diaphragm
and can be used for gage or differential
pressure measurements.
However, 300 psi (SX7300D) can be
applied to pressure port P2 only. Pressure
port P1 is able to handle operating pressures
up to 150 psi only.
This product is packaged either in
SenSym′s standard low cost chip carrier
"button" package, a plastic ported "N"
package, a metal TO can package or a dual
inline package (DIP). All packages are
designed for applications where the sen-
sing 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 four-pin
SIP configuration is provided for electrical
connection to the button or "N" package.
The TO can offers a 5-pin open bridge
configuration.
Because of its high-impedance bridge, the
SX Series is ideal for portable and low
power or battery operated systems. Due
to its low noise, the SX is an excellent choice
for
medical
and
measurements.
