The Honeywell 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 Honeywell 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 Honeywell 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.

FEATURES
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
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
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 industryleading 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-020E 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 storage life, when inside sealed moisture bag as specified (<30ºC/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
Output: ratiometric analog; I2C- or SPI-compatible 14-bit digital output (min. 12-bit sensor resolution)
Accelerates performance through reduced conversion requirements and the convenience of direct interface to microprocessors.
Small size
Miniature 10 mm x 10 mm [0.39 in x 0.39 in] package is very small when compared to many board mount pressure sensors:
• Occupies less area on the PCB
• Typically allows for easy placement on crowded PCBs or in small devices REACH and RoHS compliant Liquid media option
