Honeywell’s TruStability® TSC Series and NSC Series are piezo-
resistive 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.
• Compensated temperature range is 0 °C to 85 °C [-32 °F
to 185 °F].
• Operating temperature range is -40 °C to 85 °C [-40 °F to
185 °F].
• Measures differential or gage pressures.
NSC Series:
• Uncompensated and unamplified.
• Allows customers the flexibility of performing their own
calibration while still benefiting from the industry-leading
stability, accuracy, and repeatability that the Honeywell
TruStability
®
Pressure Sensors provide.
• Operates as specified from -40 °C to 85 °C [-40 °F
to 185 °F].
• Measures absolute, differential or gage pressures.
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 for non-corrosive, non-ionic liquids on sensors rated
above 60 mbar | 6 kPa | 1 psi.
The TSC and NSC Series offer numerous package styles and
mounting options, making it easier for device manufacturers to
integrate the product into their applications. These sensors offer
infinite resolution on the pressure signal. Frequency response is
also typically limited only by the end user’s system. All products
are designed and manufactured according to ISO 9001.

Background
POTENTIAL MEDICAL APPLICATIONS
Pneumatic control applications have a flow or pressure
generation source, a compressor or pump, that is used in
conjunction with valves to control actuators in a wide variety of
medical equipment.
The pressure sensors are used for both monitoring and control
of pneumatic flow and system pressure for more precise and
efficient performance
Some of the pneumatic circuits prevalent in medical applications
are:
• Respiratory breathing circuits:
- Nebulizers (Figure 1)
- Spirometers (Figure 2)
- Patient monitoring equipment (Figure 3)
• Flow/pressure control:
- Therapeutic hospital beds (Figure 4))
• Gas collection/delivery:
- hospital gas supply (Figure 5)
- oxygen concentrators (Figure 6)
• Precise sampling/gas ow:
- Blood analysis (Figure 7)
- Gas chromatography (Figure 8)
- Analytical instrument sampling systems (Figure 9)
