ABSTRACT:
In a tubular pressure transducer element, the axial stress imparted to the element is reduced relative to the radial stress by inserting a rigid core inside the tubular element. The reduction in stress is proportional to the ratio between the area of the full diameter of the tubular element and the area of the annulus represented by the wall thickness of the tubular element.
