Patent-Anspruch:Patent claim: Vorrichtung zum Anzeigen der Druckunterschiede in zwei gesonderten Luffrohrleitungen, bestehend aus zwei mit diesen Leitungen verbundenen druckmessenden Federn (Plattenfedern, Bourdonfedern u. dergl.), die beide, aber jede der anderen entgegenwirkend, einen und denselben Hebel des Zeigerwerkes beeinflussen , so dafs dieser stets von der dem gröfseren Druck ausgesetzten Feder in einem Mafse bewegt wird, welches dem Drucküberschufs entspricht.Device for displaying the pressure differences in two separate air ducts, consisting of two pressure-measuring springs connected to these lines (diaphragm springs, Bourdon feathers and the like), both, but each counteracting the other, one and influence the same lever of the pointer mechanism, so that this always differs from that greater pressure exposed spring is moved in an amount that the excess pressure is equivalent to.
