发明名称
摘要 <p>A diaphragm arrangement is provided for pressure measuring transducer devices wherein the diaphragm includes a structure of the flexible portions thereof permitting stable calibration and compensation of environmental conditions during measurements. In particular, the diaphragm structure includes concentric annular grooves at opposite surfaces of the diaphragm to form at least one annular rim having elastic tubular walls normal to the diaphragm surfaces, thereby providing the flexible portion of the diaphragm. The connection of the diaphragm to the transducer structure is apart from this flexible construction, and the construction can be varied to suit the conditions of usage.</p>
