The pressure is on. The answer is here. No matter the need,
Honeywell Sensing and Control (S&C) has the microstructure,
pressure sensor solution. Our sensing element design consists
of four piezoresistors galvanized with a thin, chemically etched
silicon diaphragm. A pressure change will fl ex the mechanism,
causing a strain in the diaphragm and the buried resistors.
The resistor values will change in proportion to the stress

ULTRA-LOW PRESSURE SENSORS
ASDX Series.
Features: Calibrated and temperature
compensated • ASIC-enhanced output
• Analog output with 12-bit resolution
• 12-bit digital output (I
2
C- or SPI-
compatible protocol) • Ratiometric output
• Enhanced response time and accuracy
• DIP package • Cost effective
Bene ts: Fully calibrated and temperature
compensated with on-board ASIC
designed to provide digital correction
of sensor offset, sensitivity, temperature
coeffi cients, and non-linearity. Analog
output ratiometric with supply voltage over
compensated supply range with 12-bit
resolution. 12-bit I
2
C- or SPI-compatible
protocol allows easy interfacing to most
commonly used microcontrollers and
microprocessors without additional
components and electronic circuitry.
Output is corrected pressure value in
hexadecimal format with 12-bit accuracy
(unsigned) and independent of the supply
voltage. Offers high level output on a cost-
effective basis. Intended for use with non-
corrosive, non-ionic working fl uids such as
air and dry gases in potential applications
such as fl ow calibrators, ventilation and
airfl ow monitors, gas fl ow instrumentation,

CPCL Series.
Features: Calibrated and temperature
compensated • Cost effective • Small
size • Constant voltage excitation • High
impedance, low current
Bene ts: Integrates silicon
micromachined sensing technology,
temperature compensation, and
calibration in a small, cost-effective
package. Tube arrangements with nylon
housings available for various pressure
applications, especially those requiring
small size or vacuum reference. Although
designed for use with non-corrosive,
non-ionic pressure media, sensors may
accommodate many potential medical
application gases.
CPXL Series.
Features: Non-calibrated and non-
temperature compensated • Small size
• Cost effective • Constant voltage
excitation • High impedance, low current
Bene ts: Integrates silicon micromachined
sensing technology in a cost-effective
package. Tube arrangements with nylon
housings available for various pressure
applications, especially those requiring
small size, or vacuum reference. Although
designed for use with non-corrosive,
non-ionic pressure media, accommodates
many potential medical application gases.
DCXL-DS Series.
Features: Calibrated and temperature
compensated • Improved stress isolation
• Reduced output offset errors
Bene ts: Based on proprietary technology
designed to reduce output offset or
common mode errors due to changes in
temperature, warm-up, long-term stability
and position sensitivity. Features calibrated
offset, full scale span and thermal error
calibration to promote accuracy for fl ow
pressure measurement. Industry-standard,
ported package with improved stress
isolation for printed circuit board mount
applications. Used in medical, HVAC and
industrial instrumentation applications.
XCAL Series.
Features: Calibrated and temperature
compensated • Cost effective • Constant
voltage excitation • Ratiometric output
Bene ts: State-of-the-art silicon
micromachined pressure sensors. Stress-
free packaging techniques provide
applied, which produces an electrical output. So you’ll fi nd
our components performing in potential applications including
dialysis equipment, blood analysis, centrofusion and oxygen and
nitrogen gas distribution, HVAC devices, data storage, process
controls, industrial machinery, pumps, and robotics. Honeywell
S&C is always working harder, no matter the situation. Or the
pressure.
