General Description
e www.allsensors.com
The Miniature series pressure sensors are based upon a proprietary technology to reduce the size of the sensor and
yet maintain a high level of performance. This model provides a calibrated millivolt output with superior output
offset characteristics. 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 calibrated and temperature 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 C-GRADE is a lowest cost version of the millivolt output pressure sensors.

Specification Notes
note 1: All parameters are measured at 12.0 volt excitation, for the nominal full scale pressure and room temperature unless
otherwise specified. Pressure measurements are with positive pressure applied to Port B.
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.
