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 nonlinearity 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.

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.
