BDS Series

The BDS Basic Pressure Sensor was designed with the idea of combining two sensing elements into one package. This sensor is designed to provide a precise fl ow measurement by combining a differential and absolute sensing element in the same package. By combining the differential and absolute sensing element, engineers can save cost and space in today’s smaller devices.   The 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. Output offset errors due to position sensitivity; packaging stress and long term drift are all signifi cantly reduced when compared to conventional silicon sensors. In addition, the sensor utilizes a silicon, micromachined, stress concentration enhanced structure to provide a very linear output to measured pressure.   This series is intended for use with non-corrosive, non-ionic working fl uids such as air, dry gases and the like. The output of the device is ratiometric to the supply voltage.

Specification notes

NOTE 1: ALL PARAMETERS ARE MEASURED AT 5.0 VOLT EXCITATION, FOR THE NOMINAL FULL SCALE PRESSURE AND ROOM TEMPERATURE
UNLESS OTHERWISE SPECIFIED. PRESSURE MEASUREMENTS ARE WITH POSITIVE PRESSURE TO PORT B.

NOTE 2: SHIFT IS RELATIVE TO 25°C.

NOTE 3: SHIFT IS WITHIN THE FIRST YEAR OF OPERATION.

NOTE 4: MEASURED AT ONE-HALF FULL SCALE RATED PRESSURE USING BEST STRAIGHT LINE CURVE FIT.

NOTE 5: PARAMETER IS CHARACTERIZED AND NOT 100% TESTED. MINIMUM AND MAXIMUM VALUES INDICATED AS A DESIGN REFERENCE.
