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 on a chemically etched silicon diaphragm.
A pressure change will cause a strain in the diaphragm and the
buried resistors. The resistor values will change in proportion
to the stress applied, which produces an electrical output. You

technology combines high sensitivity with
high overpressure and burst pressure
to give the customer more flexibility
in sensor implementation and reduce
the customer design requirements for
protecting the sensor without sacricing
the ability to sense very small changes
in pressure. Industry-leading long-term
stability minimizes system calibration
needs, maximizes system performance,
and helps support system uptime

by eliminating the need to service or
replace the sensor during its application
life. Industry-leading Total Error Band
provides the sensor’s true accuracy over a
compensated temperature range of
0 °C to 50 °C [32 °F to 122 °F], eliminating
individual sensor testing and calibration
(which can increase manufacturing time
and process) supporting system accuracy
and warranty requirements, helping
optimize system uptime, and providing
excellent sensor interchangeability.
Industry-leading accuracy reduces
software needed to correct system
inaccuracies, minimizing system design
time, supporting system accuracy and
warranty requirements, and helping
to optimize system uptime. High burst
pressures above 415 inH

O (1034 mbar)
allow the sensor to endure a wide range of
conditions while maintaining a high level
of sensitivity which measures even the
smallest change in pressure, simplifying
the design process. High working
pressure ranges above 135 inH

O
(336 mbar) allow the sensors to be used
continuously well above the calibrated
pressure range. Modular, exible
design with many package styles (with
the same industry-leading stability),
pressure ports, and options simplify
integration into the device manufacturer’s
application. Onboard signal conditioning
typically allows for the removal of signal
conditioning components from the PCB,
reducing costs and simplifying production
processes. Pressure ranges from ±2.5

O provide support
for many unique applications. Meets IPC/
JEDEC J-STD-020D.1 Moisture Sensitivity
Level 1 requirements which allows the
customer to avoid the thermal and
mechanical damage during solder reflow
attachment and/or repair that lesser rated
products would incur, and allows unlimited
oor life when stored as specied (<30 ºC/
85 %RH), simplifying storage and
reducing scrap. Customers may position
the sensor in the most optimal point
in the system, eliminating concern for
positional effects. Reduced susceptibility
to application-specic vibration that
occurs with changes in pressure
minimizes inaccurate pressure readings.
Custom calibration typically allows for
the removal of additional components
associated with signal conditioning from
the PCB, reducing PCB size as well
as costs often associated with those
components. Internal diagnostic functions
increase system reliability. Extremely low
power consumption (less than 10 mW,
typ.), provides extended battery life,
will 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.
