CPC/CPCL Series and CPXL Series Compensated/Calibrated and Uncompensated/Uncalibrated Board Mount Pressure Sensors DESCRIPTION The CPC/CPCL Series and the CPXL 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. While the compensation, and calibration in a complete family of low cost sensors are designed for use with non-corrosive, nonionic packages. This series offers the most cost-effective solution for pressure media, they accommodate many gases that are used design requirements. in medical applications. These piezoresistive pressure sensors use micromachined The CPC Series is designed for the lowest cost and smallest silicon chips mounted on a ceramic and protected with a plastic profile. The standard packages have only a plastic cap for cap. Several tube arrangements with nylon housings are OEM applications. The CPC axial port option accommodates available for various pressure applications. pressure measurements in tube 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 CPC/CPCL Series and CPXL Series Table 1.
