XPC/XPCL Series and XPXL Series Compensated/Calibrated and Uncompensated/Uncalibrated Board Mount Pressure Sensors DESCRIPTION The XPC/XPCL Series and XPXL Series sensors integrate On devices of 5 psi and above, the top side of the chip is silicon micromachined sensing technology, temperature protected against humidity by a Silgel coating. compensation, and calibration in a complete family of low-cost packages. This series offers a cost-effective solution for design Although the sensors are designed for use with noncorrosive, requirements. nonionic pressure media, they accommodate many gases that are used in medical applications. These piezoresistive pressure sensors use micromachined silicon chips mounted on ceramic and protected with a plastic cap. Several tube arrangements with nylon housings are available for various pressure applications. FEATURES POTENTIAL APPLICATIONS Low cost, small size Medical applications Temperature compensated Applications requiring small size Zero and span calibrated Applications requiring vacuum and positive pressure Millivolt output reference or both Differential, gage and absolute pressure Constant voltage excitation High impedance - low current XPC/XPCL Series and XPXL Series Table 1.
