Abstract
Abstract An electro mechanical power- or pressure-measuring-transformer with a body elastically deformable under the influence of the value to be measured. The deformation of the body is transformed in corresponding electric values, wherein the elastic deformable body comprises non-metallic, inorganic working material constituting a ceramic material.
