SM4XXX Gauge & Differential Pressure Sensors Medium Ranges

The SM4XXX Series is a digital and analog, medium pressure MEMS sensor family offering state-of-the-art pressure transducer technology and CMOS mixed signal processing technology to produce a digital, fully-conditioned, multi-order pressure and temperature-compensated sensor in SOIC-16 package with a dual vertical porting option. It is available in both compound gauge or differential pressure configurations. With the dual porting, a vacuum gauge measurement is possible to minimize altitude errors due to changes in ambient pressure.

The SM4X91 Series has both I2C & analog outputs while the SM4X21 Series has I2C only.

The pressure sensor can be mounted directly on a standard printed circuit board and a high level, calibrated pressure signal can be acquired from the digital interface. This eliminates the need for additional circuitry, such as a compensation network or a microcontroller containing a custom correction algorithm.

FEATURES

  • Pressure ranges from 2.5 psi to 14.9 psi in gauge (SM42X1), differential, (SM43X1) or asymmetrical (SM44X1) configurations
