GENERAL INFORMATION
Honeywell’s TruStability
®
High Accuracy Silicon Ceramic (HSC)
Series and Standard Accuracy Silicon Ceramic (SSC) Series are
piezoresistive silicon pressure sensors offering a digital or analog
output for reading pressure over the specified full scale pressure
span and temperature range.
These sensors measure absolute, gage, or differential pressures.
The absolute versions have an internal vacuum reference and an
output value proportional to absolute pressure. Gage versions
are referenced to atmospheric pressure and provide an output
proportional to pressure variations from atmosphere. Differential
versions allow measurement of pressure between the two
pressure ports.
The HSC Series is calibrated over the temperature range of 0 °C
to 50 °C [32 °F to 122 °F] while the SSC Series is calibrated over
the temperature range of -20 °C to 85 °C [-4 °F to 185 °F].
The TruStability
®
pressure sensors are intended for use with
non-corrosive, non-ionic gases, such as air and other dry gases.
An available option extends the performance of these sensors to
non-corrosive, non-ionic liquids for pressure ranges above
40 mbar | 4 kPa | 20 inH

CLEANING
CAUTION
IMPROPER CLEANING
Avoid cleaning the sensor; however, if it must be cleaned
ensure cleaning fluids, such as appropriate alcohols
or fluorinated solvents, are used based on the type of
contaminants to be removed. Do not immerse the sensor.
Failure to comply with these instructions may result in
product damage.

CAUTION
PRODUCT DAMAGE FOR SENSORS WITH LIQUID MEDIA
OPTION (ONLY AVAILABLE 60 MBAR | 6 KPA | 1 PSI AND
ABOVE)
• Ensure liquid media is applied to Port 1 only; Port 2 is not
compatible with liquids.
• Ensure liquid media contains no particulates. All TruStability
®
sensors are dead-ended devices. Particulates can
accumulate inside the sensor, causing damage or affecting
sensor output.
• Recommend that the sensor be positioned with Port 1 facing
downwards; any particulates in the system are less likely
to enter and settle within the pressure sensor if it is in this
position.
• Ensure liquid media does not create a residue when dried;
build-up inside the sensor may affect sensor output.
Rinsing of a dead-ended sensor is difficult and has limited
effectiveness for removing residue.
• Ensure liquid media are compatible with wetted materials.
Noncompatible liquid media will degrade sensor
performance and may lead to sensor failure.
Failure to comply with these instructions may result in
product damage.
Absolute maximum ratings are the extreme limits the device will with-
stand without damage.
Incorrect application of supply voltage or ground to the wrong pin may
cause electrical failure.
