Abstract
Systems and methods for packaging a MEMS device to measure the in-stream pressure within a pipe are provided. Embodiments herein avoid the use of a metal housing enclosing the MEMS device or die pad of the MEMS device. Instead, the MEMS device is mounted directly to the pipe using a ceramic carrier. In preferred embodiments, the ceramic carrier is soldered, brazed, welded or eutectic bonded to the metal pipe.
