Abstract

내연기관의 연소실에서 압력 감지를 위한 압력 변환기에 있어서 멤브레인(14)이 대략 중앙의 비드(35)를 갖는다. 이 비드(35)의 영역에 압력 변환기(11)의 플런저(18)가 멤브레인(14)에 인접한다. 또한 하우징 웨브는 멤브레인(14)에 의해 덮히는 개구(13)의 영역에서 나머지 영역에서 보다 더 작은 벽 두께를 갖는다. 하우징 웨브(38)의 형상 및 멤브레인(14)의 비드(35)의 깊이를 구조적으로 정하여 소위 열 충격 에러를 보상할 수 있다. 압력 변환기(11)의 구성이 단순하므로, 압력 변환기는 저렴하게 제조될 수 있다. 엠브레인(14)과 하우징의 앞부분의 영역에서 온도 하락에 의해 나타나는 측정 에러가 제거될 수 있다.In a pressure transducer for pressure sensing in a combustion chamber of an internal combustion engine, the membrane 14 has approximately a central bead 35. In the region of the beads 35, the plunger 18 of the pressure transducer 11 is adjacent to the membrane 14. The housing web also has a smaller wall thickness in the region of the opening 13 covered by the membrane 14 than in the rest of the region. The shape of the housing web 38 and the depth of the beads 35 of the membrane 14 can be structurally determined to compensate for the so-called thermal shock errors. Since the configuration of the pressure transducer 11 is simple, the pressure transducer can be manufactured at low cost. The measurement error caused by the temperature drop in the area of the embrane 14 and the front of the housing can be eliminated.
