CPC/CPCL and
CPX/CPXL Series
Uncompensated/Compensated
and Compensated Calibrated
Silicon Pressure Sensors
DESCRIPTION
The CPX/CPXL and the CPC/CPCL Series sensors integrate
silicon micromachined sensing technology, temperature
compensation, and calibration in a complete family of low cost
packages. This series offers the most cost-effective solution for
design requirements.
The CPC Series is designed for the lowest cost and smallest
These piezoresistive pressure sensors use micromachined
silicon chips mounted on a ceramic and protected with a plastic
cap. Several tube arrangements with nylon housings are
available for various pressure applications.

POTENTIAL APPLICATIONS
Medical applications
Applications requiring small size
Applications requiring vacuum and positive
Pressure reference, or both
profile. The standard packages have only a plastic cap for
OEM applications. The CPC axial port option accommodates
pressure measurements in tube applications.
On devices of 5 psi and above, the top side of the chip is
protected against humidity by a Silgel coating. While the
sensors are designed for use with non-corrosive, nonionic
pressure media, they accommodate many gases that are used
in medical applications.
