HONEYWELL SDX15G2 Datasheet

SDX Series

Plastic Silicon Pressure Sensors
Low Cost, Temperature
Compensated, DIP, 0 psi to 1 psi,
0 psi to 100 psi

DESCRIPTION

The SDX Series sensors provide a very cost-effective solution
for pressure applications that require small size plus
performance. These calibrated and temperature-compensated
sensors give an accurate and stable output over a 0 °C to 50
°C [32 °F to 122 °F] temperature range. This series is intended
for use with non-corrosive, non-ionic working fluids such as air
and dry gases.

Devices are available to measure absolute and gage pressures
from 1 psi (SDX01) up to 100 psi (SDX100). The absolute
devices have an internal vacuum reference and an output
voltage proportional to absolute pressure. The SDX devices
are available in standard commercial and prime grades
(SDCXXXXX-A) to allow optimization of accuracy and cost in
any given application.

FEATURES

• Low cost DIP

• Precision temperature compensation

• Calibrated zero and span

• Small size

• Low noise

• High impedance for low power applications

• Prime grade available (SDXxxxyy-A)

The SDX devices feature an integrated circuit (IC) sensor
element and laser trimmed thick film ceramic housed in a
compact solvent resistant case. The package is a double-wide,
dual-inline package (DIP). This is the same familiar package
used by IC manufacturers except it is only 11,94 mm [0.470 in]
long and has a pressure port(s). The PC board area used by
each DIP is approximately 0.26 in
enables the use of multiple sensors in limited available space.
The DIP provides excellent corrosion resistance and isolation
to external package stress.

The DIP mounts on a PC board like a standard IC with
through-hole pins. The pins anchor the pressure sensor to the
PC board and provide a more secure and stable unit than other
types of packages.

The output of the bridge is ratiometric to the supply voltage and
operation from any dc supply voltage up to 20 Vdc is
acceptable.

• Computer peripherals
