Measuring pressure with compensated silicon sensors and precision delta-sigma ADCs

Reasonably priced sensors are now available in a variety of packages, making them attractive for a wide variety of embedded system precision sensing applications, including liquid level measurements. This article describes differences among modern pressure sensors and emphasizes the benefits of recent advances in microelectro mechanical (MEMS) temperature-compensated, silicon pressure sensors. The article then describes a cost-effective, low-power, liquid …
