Abstract
A diaphragm arrangement for a pressure transducer, particularly one employed in monitoring an internal combustion engine and employing a force measuring transducer element abuts either against the pressure transducer directly or a preload element coupled therewith. The diaphragm arrangement includes a plurality of ring-shaped portions, one coupled to a preload volt element and another at the periphery of the transducer. Between these inner and outer portions of the diaphragm arrangement is an elastic portion interconnecting the two which permits the transducer to accurately monitor the pressure behavior, without the introduction of errors due to temperature shocks acting on the diaphragm during the measurement.
