Basic Board Mount Pressure Sensors
High Accuracy, Compensated/Amplified
60 mbar to 10 bar | 6 kPa to 1 MPa | 1 psi to 150 psi
Digital or Analog Output, Liquid Media Capable
DESCRIPTION
The ABP Series are piezoresistive silicon
pressure sensors offering a ratiometric
analog or digital output for reading
pressure over the specified full scale
pressure span and temperature range.
They are calibrated and temperature
compensated for sensor offset,
sensitivity, temperature effects and
accuracy errors (which include non-
linearity, repeatability and hysteresis)
using an on-board Application Specific
Integrated Circuit (ASIC). Calibrated
output values for pressure are updated
at approximately 1 kHz for analog and
2 kHz for digital. All products are
designed and manufactured according
to ISO 9001 standards.
• Dry gases option: The input port is
limited to non-corrosive, non-ionic
media (e.g., dry air, gases) and should
not be exposed to condensation. The
gases are limited to media compatible
with high temperature polyamide,
silicone, alumina ceramic, silicon, gold,
and glass.
• Liquid media option: Includes an
additional silicone-based gel coating
to protect the electronics under
port P1, which enables use with
non-corrosive liquids (e.g. water and
saline) and in applications where
condensation can occur. Since port P2
is designed for use with non-corrosive
liquids, this option is often suitable for
wet-wet differential sensing.
DIFFERENTIATION
• Enhanced accuracy helps the design
engineer fully understand the error in
measurement.
• Wide supply voltage range offers
design flexibility.
• Power consumption when utilizing
sleep mode option allows for use in
battery-powered applications.
VALUE TO CUSTOMERS
• Simplifies design-in: Small size
saves room on the PC board (PCB),
or simplifies design in smaller and
lower power devices. Meets Moisture
Sensitivity Level 1 requirements, which
allows for unlimited shelf life when
stored at <30 ºC/85 %RH and, under
most storage conditions, allows for
PCB soldering without any material
concern about solder joint quality due
to aging of the sensor terminals, which
minimizes the concern about aging
of the terminals prior PCB assembly.
Pressure choices allow engineers
to select range required for their
application. Leadless SMT, SMT, and
DIP package options.
• Cost-effective: Small size helps
engineers reduce design and
manufacturing costs while maintaining
enhanced performance and reliability
of the systems they design.
• Accurate: Total Error Band (TEB) and
wide pressure range enable engineers
to optimize system performance by
improving resolution and system
accuracy. Optional internal diagnostics
validate that the sensor readings are
correct.
• Flexible: Supply voltage range, variety
of pressure units, types, and ranges,
output options, and wide operating
temperature range simplify use in the
application.
• Versatile: Wet-media compatibility,
sleep mode, and temperature
output options make the sensor a
versatile choice for Internet of Things
applications.
• Honeywell Brand: Utilize proprietary
Honeywell technology, and are
protected by multiple global patents.
POTENTIAL APPLICATIONS
Medical: CPAP, blood analysis, blood
pressure monitoring, breast pumps,
drug dosing, hospital beds, massage
machines, oxygen concentrators,
patient monitoring, sleep apnea

Industrial: Air brakes, HVAC/
transmitters, life sciences, material
handling, pneumatic control and
regulation, process gas monitoring,

FIGURE 1. TOTAL ERROR BAND
Total Error Band (TEB) is a single specification that includes
all possible sources of error. TEB should not be confused with
accuracy, which is actually a component of TEB. TEB is the worst
error that the sensor could experience. The TEB specification
on a datasheet may be confusing. Honeywell uses the TEB
specification in its datasheet because it is the most comprehensive
measurement of a sensor’s true accuracy. Honeywell also
provides the accuracy specification in order to provide a common
comparison with competitors’ literature that does not use the
TEB specification. Many competitors do not use TEB—they simply
specify the accuracy of their device. Their accuracy specification,
however, may exclude certain parameters. On their datasheet, the
errors are listed individually. When combined, the total error (or
what would be TEB) can be significant.
