Abstract
Aspects of the subject technology relate to an apparatus having a housing including a port exposed to an environment. A pressure sensor is disposed within the housing to measure a pressure of the environment. A medium partially fills a sensor cavity or is coated over the pressure sensor, and a cap including multiple openings is disposed over the pressure sensor. The openings of the cap are arranged to be offset from the port.
Claims21
