The Miniature BASIC series pressure sensors are based upon a proprietary technology to reduce the size of the sensor
and yet maintain a high level of performance. The technology is currently being patented. Output offset errors due to
change in temperature, stability to warm-up, stability to long time period, and position sensitivity are all significantly
reduced when compared to conventional compensation methods. In addition the sensor utilizes a silicon, micromachined,
stress concentration enhanced structure to provide a very linear output to measured pressure.
These offset compensated sensors give an accurate and stable output over a wide temperature range. This series is
intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like.
The output of the device is ratiometric to the supply voltage and operation from any D.C. supply voltage up to +6V is
acceptable.

Specification Notes
NOTE 1: ALL PARAMETERS ARE MEASURED AT 4.5 VOLT EXCITATION, FOR THE NOMINAL FULL SCALE PRESSURE AND ROOM TEMPERATURE
UNLESS OTHERWISE SPECIFIED. PRESSURE MEASUREMENTS ARE WITH NEGATIVE PRESSURE APPLIED TO THE TOP-PORT (THE ONLY PORT
FOR THE SINGLE PORT) CONFIGURATION.
NOTE 2: SHIFT IS RELATIVE TO 25°C.
NOTE 3: SHIFT IS WITHIN THE FIRST HOUR OF EXCITATION APPLIED TO THE DEVICE.
NOTE 4: MEASURED AT ONE-HALF FULL SCALE RATED PRESSURE USING BEST STRAIGHT LINE CURVE FIT.
NOTE 5: THE VOLTAGE ADDED TO THE OFFSET VOLTAGE AT FULL SCALE PRESSURE.
Pressure Response: for any pressure applied the response time to get to 90% of pressure applied is typically less
than 100 useconds.
