TruStability® Board Mount Pressure Sensors
The TruStability® High Accuracy Silicon Ceramic (HSC) Series is a piezoresistive silicon pressure sensor offering a ratiometric
analog or digital output for reading pressure over the specified full scale pressure span and temperature range.
The HSC Series is fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-
linearity using an on-board Application Specific Integrated Circuit (ASIC). Calibrated output values for pressure are updated at
approximately 1 kHz for analog and 2 kHz for digital.
The HSC Series is calibrated over the temperature range of 0 °C to 50 °C [32 °F to 122 °F]. The sensor is characterized for
operation from a single power supply of either 3.3 Vdc or 5.0 Vdc.
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 TruStability® pressure sensors are intended for use with non-corrosive, non-ionic gases, such as air and other dry gases.
Available options extend the performance of these sensors to non-corrosive, non-ionic liquids for pressure ranges above
40 mbar | 4 kPa | 20 inH2O.
All products are designed and manufactured according to ISO 9001 standards.

PROPRIETARY HONEYWELL TECHNOLOGY
Combines high sensitivity with high overpressure and burst pressure while
providing industry leading stability—performance factors that are difficult to
achieve in the same product; this gives the customer more flexibility in sensor
implementation and reduces the customer design requirements for protecting the
sensor without sacrificing the ability to sense very small changes in pressure.
PROTECTED BY MULTIPLE GLOBAL PATENTS
INDUSTRY-LEADING LONG-TERM STABILITY
Even after long-term use and thermal extremes, the sensor’s stability remains best
in class:
• Minimizes system calibration needs.
• Improves system performance.
• Helps support system uptime by minimizing the need to service or replace the
sensor during its application life.
TOTAL ERROR BAND (TEB)
Honeywell specifies TEB—the most comprehensive, clear, and meaningful
measurement—that provides the sensor’s true performance over a compensated
range of 0 °C to 50 °C [32 °F to 122 °F] (see Figure 1):
• Minimizes individually testing and calibrating every sensor, decreasing
manufacturing time and process costs.
• Improves system accuracy.
• Provides enhanced sensor interchangeability—there is minimal part-to-part
variation in accuracy.

Features
and Benefits
INDUSTRY-LEADING ACCURACY
Extremely tight accuracy of ±0.25 %FSS BFSL (Full Scale Span Best Fit Straight
Line) reduces software needed to correct system inaccuracies, minimizing system
design time:
• Avoids additional customer calibration.
• Helps to improve system efficiency.
• Often simplifies software development.
HIGH BURST PRESSURES
• Promotes system reliability and reduces potential system downtime.
• Can simplify the design process.
HIGH WORKING PRESSURE RANGES
Allows ultra-low pressure sensors to be used continuously well above the
calibrated pressure range.
INDUSTRY-LEADING FLEXIBILITY
Modular, flexible design with many package styles (with the same industry-
leading stability), pressure ports, and options simplify integration into the device
manufacturer’s application.
WIDE VARIETY OF PRESSURE RANGES
From ±1.6 mbar to ±10 bar | ±160 Pa to ±1 MPa | ±0.5 inH2O to 150 psi provide
support for many unique applications.
MEETS IPC/JEDEC J-STD-020D.1 MOISTURE SENSITIVITY LEVEL
1 REQUIREMENTS
• Allows the customer to avoid the thermal and mechanical damage during
solder reflow attachment and/or repair that lesser rated products would incur.
• Allows unlimited floor life when stored as specified (<30 ºC/85 %RH),
simplifying storage and reducing scrap.
• Never requires lengthy bakes prior to reflow.
• Stable and usable shortly after reflow process allows for lean manufacturing.
OPTIONAL INTERNAL DIAGNOSTIC FUNCTIONS
• May reduce the need for redundant sensors in the system.
• Detects most internal failures including burst sensors.
ENERGY EFFICIENT
Extremely low power consumption (less than 10 mW, typ.):
• Reduces system power requirements.
• Enables extended battery life.
• Optional sleep mode available upon special request.
