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

technology combines high sensitivity with
high overpressure and burst pressure
to give the customer more fl exibility
in sensor implementation and reduce
the customer design requirements for
protecting the sensor without sacrifi cing
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
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

The human body is a
supremely sensitive
mechanism, requiring equally
perceptive observation.
Honeywell S&C offers a line
of pressure sensors equal
to every task — including
sensors that measure the
amount of pressure delivered
to the human body.
From medical applications
to industrial needs to any
industry, we’ve got the right
solution. Our categories of
pressure sensor measurement
include absolute, differential,
gage or vacuum gage —
with unamplifi ed or amplifi ed
sensors covering a pressure
range of 0 psi to 250 psi
(0 bar to 17.24 bar). You’ll
also fi nd a variety of mounting

output, small size, reduced
cost, enhanced reliability,
enhanced repeatability and
accuracy under extreme
conditions, enhanced
operating characteristics
between sensors, and
interchangeability without
recalibration.
