Abstract
A dual pressure sensor apparatus configured for attachment to a manifold includes a molded plastic housing with a body portion featuring an upper cavity, a measurement port, and a lower cavity closed by the manifold. First and second pressure sensor modules are mounted in first and second wells formed in the upper cavity, and electrically coupled to a set of leadframe terminals disposed in the upper cavity. An opening in the first well couples the first pressure sensor module to the measurement port, and an opening in the second well couples the second pressure sensor module to the lower cavity. The measurement port sealingly extends through an opening in the manifold so that the first pressure sensor module measures pressure in the manifold, and the body portion walls bounding the lower cavity are notched so that the second pressure sensor module measures atmospheric or barometric pressure outside the manifold.
