Features
- 10 in H2O Full Scale to 100 psi Full
Scale Pressures
- 0.5 % linearity
- Small LCC Footprint
- ROHS Compliant
- SMI SM5310 compatible
Applications
- Medical Instrumentation

General Description
- The BASIC Series of pressure sensors use a silicon micromachined
(MEMS) pressure sensor in the most basic configuration.
- Silicon Microstructures Inc SM5310 series compatible
surface mount
- The package is a ceramic surface mount configuration
to provide the smallest footprint possible.
- Best temperature compensation is realized when the sensor
has a constant current excitation.
- This series is intended for use with non-corrosive,
non-ionic working fluids such as air, dry gases and the
like.
- Specifications are written for constant voltage of 3.0
volts.
- The output of the device is ratiometric to the supply
voltage.

Specification Notes
(1): All parameters are measure at 3.0
volt excitiation, for the nominal full scale pressure and
room temperature unless otherwise specified. Pressure measurements
are with positive pressure to the single port configuration.
(2): Shift is relative to 25°C.
(3): Shift is within the first year of
operation.
(4) Measure at one-half full scale rated
pressure using best straight curve fit.
(5): The voltage added to the offset voltage
at full scale pressure.
(6): Parameter is characterized and not
100% tested. Minimum and maximum values indicated as a design
reference.
All Sensors reserves the right to make
changes to any products herein. All Sensors does not assume
any liability arising out of the application or use of any
product or circuit described herein, neither does it convey
