Abstract
The invention relates to a fluid pressure sensing device comprising a pressure sensing transducer having a support structure and a diaphragm attached to said support structure, the diaphragm having a fluid facing side. A housing has a transducer receiving cavity defined by a bottom wall and a housing sidewall extending upwardly from the bottom wall. The bottom wall is formed with a fluid pressure receiving recess. A fluid pressure port is formed in the housing in communication with the recess. The diaphragm is positioned between the support structure and the fluid pressure receiving recess and a seal material around a support structure sidewall fixes the pressure sensing transducer in the housing and provides a hermetic seal.
