CPC/CPCL and CPX/CPXL Series Uncompensated/Compensated and Compensated Calibrated Silicon Pressure Sensors DESCRIPTION On devices of 5 psi and above, the top side of the chip is The CPX/CPXL and the CPC/CPCL Series sensors integrate protected against humidity by a Silgel coating. While the silicon micromachined sensing technology, temperature sensors are designed for use with non-corrosive, nonionic compensation, and calibration in a complete family of low cost pressure media, they accommodate many gases that are used packages. This series offers the most cost-effective solution for in medical applications. design requirements. The CPC Series is designed for the lowest cost and smallest These piezoresistive pressure sensors use micromachined profile. The standard packages have only a plastic cap for silicon chips mounted on a ceramic and protected with a plastic OEM applications. The CPC axial port option accommodates cap. Several tube arrangements with nylon housings are pressure measurements in tube applications. 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 • Millivolt output • Pressure reference, or both • Differential, gage and absolute pressure • Constant voltage excitation • High impedance - low current
