TE Connectivity's SMI SM4000/SM1000 series MEMS pressure sensors offer a measurement range from 2.5PSI to 30PSI and are available in gage, differential and asymmetric differential configurations.
These series provide a JEDEC standard SOIC-16 package with vertical or horizontal porting options or a JEDEC SOIC-10 package with a vertical port. With the dual porting, a reference measurement is possible to minimise errors due to changes in ambient pressure.
Combining the pressure sensor with a signal-conditioning ASIC in a single package simplifies the use of advanced silicon micro-machined pressure sensors. 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 microcontroller containing a custom correction algorithm.
