The TruStability
®
Standard Accuracy Silicon Ceramic (SSC) 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 SSC 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 SSC Series is calibrated over the temperature range of -20 °C to 85 °C [-4 °F to 185 °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 two
pressure ports.

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

Features
and Benefits
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 -20 °C to 85 °C [-4 °F to 185 °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.
