Abstract
An Improved Bellow-Type Pressure Sensing Apparatus is disclosed. Also disclosed is, an apparatus that provides increased pressure sensitivity without added cost and complexity in the electronic detector circuitry. The apparatus further is less sensitive to gravity, vibrations or other external influences. It is a still further object that the apparatus be available with curved bellow head, formed with either concave or convex reflective surfaces.
