TruStability™ HSC Series-High Accuracy, digital I²C address: 0x28, DIP AN: single axial barbed port, gage, 0 bar to 1 bar, 5.0 Vdc, dry gases only, no special options

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.
