The XPXL/XPX and XPCL/XPC 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.
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.
On devices of 5 psi and above, the topside of the chip is protected
against humidity by a Silgel coating. While the sensors are designed for
use with noncorrosive, nonionic pressure media, they accommodate
many gases that are used in medical applications.
