The Miniature BASIC series pressure sensors are based upon a proprietary technology to reduce the size of the sen-
sor 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 sili-
con, 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.
