Abstract

본 발명은 그것의 종축에 대해 횡으로 2개의 분할된 내부 하우징을 포함하며, 상기 내부 하우징의 하우징 섹션 사이에는 압력센서를 지지하는 중앙 다이어프램이 고정되도록 구성된, 압력차 측정 변환기에 관한 것이다. 한 하우징 섹션은 보어내에 전기 리드 스로우를 포함하며, 상기 전기 리드 스로우의 외부 쇼울더는 보어의 확대부에 놓인다.
전기 리드 스로우의 면에서 이러한 측정 변환기의 제조를 간단히 하기 위해 보어(31)가 종축(32)에 대해 평행하게 뻗고, 다른 하우징 섹션(3)을 향한 그것의 단부에 확대부(33)를 가지며, 다른 하우징 섹션(3)으로부터 떨어진 그것의 단부에서 외부로 뻗은 횡방향 보어(44)내로 이어진다.
