The invention relates to area of measuring engineering and can be used at measurement of pressure of media with abrupt changes of temperature, for instance in areas like heat power engineering, transportation of energy and account of energy, aero-space industry, propulsion engineering. Pressure transformer for medium with abrupt changes in temperature that has body, round membrane that is rigidly fixed in the lower part of the body, tenso-resistors placed on membrane, the lower part of the body in zone of fixation of membrane is arranged in form of quarter of torus. Arrangement of the lower part of the body of transformer in form of quarter of torus makes it possible to decrease thermo-mechanical stresses in membrane at measuring pressure of medium with abrupt changes on temperature and in such way to increase accuracy of measurement. |
