Description
Claims (8)
- 圧力スイッチ(1)であって、ケーシング(2)を有しており、該ケーシングが、圧力が測定可能な流体を収容するためのキャビティ(3)を有しており、当該圧力スイッチ(1)が更に、圧力を測定するための受圧部材(4)を有しており、該受圧部材が前記キャビティ(3)と流体接続しており、該キャビティ(3)が、流入部(5)から流出部(6)まで延在しており且つ流体のための流路(7)を形成しており、前記受圧部材(4)が、前記流路(7)内で前記流入部(5)と流出部(6)との間に配置されている形式のものにおいて、
前記受圧部材(4)が、一定の直径を備えた円筒形を有しており、しかも前記受圧部材(4)が、一定の穴直径を有するケーシング(2)内の穴に配置されており、前記受圧部材(4)の一方の端部が、前記流路(7)に突入して延びており且つ前記受圧部材の残りの延在部が、前記ケーシング(2)内に配置されており、流体の圧力を測定する際に、前記受圧部材(4)の周囲を巡る周流が生じて、デッドスペースが形成されないようになっていることを特徴とする、圧力スイッチ。 - 前記流路(7)が少なくとも部分的に円筒形に形成されている、請求項1記載の圧力スイッチ。
- 前記受圧部材(4)が、前記円筒形の部分の領域に配置されている、請求項2記載の圧力スイッチ。
- 前記流入部(5)と流出部(6)とが、それぞれねじ山区分(8,9)を有しており、該ねじ山区分において、ねじ山がケーシング(2)内に切られている、請求項1から3までのいずれか1項記載の圧力スイッチ。
- 前記ねじ山区分(8,9)の直径(D)が、流入部(5)と流出部(6)との間の流路(7)の直径(d)よりも大である、請求項4記載の圧力スイッチ。
- 前記流路(7)とねじ山区分(8,9)とが、それぞれ同心的な軸線(a)を有している、請求項4又は5記載の圧力スイッチ。
- 流路(7)の軸線(a)と、円筒形のピンとして形成された受圧部材(4)の長手方向軸線(L)とが、互いに垂直方向に位置している、請求項6記載の圧力スイッチ。
- 当該圧力スイッチが、測定圧力のための組み込まれた測定端子を有しているか、又は当該圧力スイッチが、マノメータと直接に接続されている、請求項1から7までのいずれか1項記載の圧力スイッチ。
