TSC Series and NSC Series are
piezoresistive silicon pressure sensors offering a ratiometric analog
output for reading pressure over the specified full scale pressure
span and temperature range.
TSC Series:
•Temperaturecompensatedandunamplified.
•Compensationmakesiteasiertointegratethesensorintoa
system by eliminating the need to calibrate the system over
temperature and also offers reduced part-to-part variation.

stability, accuracy, and repeatability that the Honeywell
TruStability

Pressure Sensors provide.

•Measuresabsolute,differentialorgagepressures.
The absolute versions have an internal vacuum reference and an
output value proportional to absolute pressure. Differential versions
allow measurement of pressure between two pressure ports. Gage
versions are referenced to atmospheric pressure and provide an
output proportional to pressure variations from atmosphere.
The TSC Series and NSC Series sensors are intended for use with
non-corrosive, non-ionic gases, such as air. Port 1 can also be used

CAUTION
PRODUCT DAMAGE
• 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 difcult and has limited
effectiveness for removing residue.
• Ensure liquid media are compatible with wetted materials.
Non-compatible liquid media will degrade sensor
performance and may lead to sensor failure.
Failure to comply with these instructions may result in
product damage.
