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.
