摘要: A sensor having freeze resistant features is disclosed. The sensor includes a sensor die and a buffer member that are assembled for attachment to a process fluid conduit. The buffer member defines an opening in fluid communication with the process fluid. The sensor die has a flexible diaphragm, and a capillary channel establishes fluid communication between the diaphragm area of the sensor die and the opening in the buffer member.
