A stress distribution plate, such as a diaphragm for a pressure transducer, has a central plane and a neutral stress plane. According to the invention, the neutral stress plane is displaced from the central plane, providing for a mechanical advantage or amplification in the operation of the stress plate or transducer. The stress plate or diaphragm may be provided with a lacunose surface region or with a predetermined and preferably symmetrical pattern of mesas and recesses for a displacement of the neutral stress plane relative to the central plane.

An improved transducer diaphragm for mounting around its periphery to a cylindrical spacer, said diaphragm comprising a plate having an even back surface and a multilevel front surface, which multilevel front surface includes an upper level spaced from said back surface, a lower level closer to said back surface than said upper level, and at least two symmetrically positioned recess portions at said lower level overlying a maximum strain amplitude section of the plate, and a strain gauge mounted on said lower level of the multilevel front surface in each of said recesses.
