The BDS Series from All Sensors Corp., Morgan Hill, CA, comprises two independent sensors—one absolute and the other differential—in a single package. Sensing ranges are 0–30 psia and 0–10 in.H2O for the BDS-L10D030A and 0–100 psia and 0–10 in.H2O for the BDS-L10D100A. The sensors are offered in a PC-board-mountable package with 2 pressure ports. Port volumes have been balanced to improve common mode response and the sensor is intended for applications involving high common-mode pressures. Features include a basic millivolt output, electrically cross-coupled sensing elements to reduce output offset and temperature errors, and simultaneous absolute and differential pressure outputs.
