Abstract

Die erfindungsgemäße Vorrichtung zur Gemischüberwachung für Gasgemische aus zwei Gasen umfasst
- zwei Einrichtungen zur Umsetzung eines Druckes in eine Kraft bzw. in einen Weg, die im folgenden als Druck-/Wegwandler bezeichnet werden, die den in den Druck-/Wegwandlern anliegenden Druck in einen Weg umwandeln und
- einen Balken der kippbar auf zwei verschiebbaren Auflagern gelagert ist, wobei jeweils ein Balkenende mit einem der Druck-/Wegwandler derart verbunden ist, dass der Balken kippt, wenn die beiden Druck-/Wegwandler nicht mehr in einem vorbestimmten Gleichgewichtsbereich sind, und
- zumindest eine Detektoreinrichtung, die ein Kippen des Balkens detektiert und ein Signal ausgibt.

Figure imgaf001
The inventive device for mixture monitoring for gas mixtures of two gases
- Two means for implementing a pressure in a force or in a way, which are referred to below as pressure / Wegwandler, which convert the voltage applied in the pressure / distance transducers pressure in a way and
a beam which is tiltably mounted on two displaceable supports, one beam end being connected to one of the pressure / displacement transducers such that the beam tilts when the two pressure / displacement transducers are no longer in a predetermined equilibrium range, and
- At least one detector device which detects a tilting of the beam and outputs a signal.
