Description

Druck- und Druckunterschiedsmeßvorrichtung Die Erfindung betrifft Druck- und Druckunterschiedsmeßvorrichtungen, bestehend aus einer Neigungswaage mit einem zwecks Änderung des Übersetzungsverhältnisses auf eienr durch die Drehachse des Waagebalkens himdurchgehenden Führung derart einstellbarem Meßgewichtssystem, daß der Schwergpunkt dieses Systems auch in die Drehachse verlegbar ist.Pressure and Pressure Difference Measuring Apparatus The invention relates to Pressure and pressure difference measuring devices, consisting of an inclination balance with one for the purpose of changing the transmission ratio on one through the axis of rotation of the balance beam in the continuous guidance of such an adjustable measuring weight system, that the focus of this system can also be relocated to the axis of rotation.

Die Erfindung besteht darin, daß bei diesen Meßvorrichtungen, die als solche Gegenstand des Patents nicht sind, das Meßgewicht in einem Rohr geführt ist und daß es außer dem an einem biegsamen Glied aufgehängt ist, das an einem ortsfesten Punkt verstellbar befestigt ist und durch eine Öffnung in der Drehachse des Waagebalkens hindurchgeht. The invention is that in these measuring devices that as such are not the subject of the patent, the measuring weight is guided in a tube and that it is also suspended from a flexible member, that from a stationary one Point is adjustable and attached through an opening in the axis of rotation of the balance beam passes through.

Durch dies Anordnung ist es möglich, die Änderung des Meßgewichtes während des Betriebes ohne Störung der Anzeige vorzunehmen, so daß bequem ohne Berührung des Meßgerätes selbst die Meßbereiche von z.B. zwie oder mehreren nebeneinanderliegenden Meßgeräten, deren Zeiger auf eienr gemeainsamen Skala spielen, abgestimmt werden können. This arrangement makes it possible to change the measured weight to make during operation without disturbing the display, so that comfortably without touching of the measuring device itself, the measuring ranges of e.g. two or more adjacent Measuring devices whose pointers play on a common scale are tuned can.

Es ist bekannt. die Zeiger zweier oder mehrerer mechanischer Druck-oder Druckunterschiedsmesser auf einer gemeinsamen Skala spielen zu lassen. It is known. the pointer of two or more mechanical pressure or Let the pressure difference meter play on a common scale.

In der Abbildung sit eine Ausführungsform des Erfindungsgedankens dargestellt. die Abbildung zeigt eine Neigungswaage mit zwei Glocken. Das Meßgewicht SG ist in einem mit dem Waagebalken verbundenen Rohr geführt, das durch die Drehachse hindurchgeht, während die Schneidenlagerungen sich beiderseits dieses Rohres befinden. Durch Verschieben des Meßgewichtes kann der Meßbereich des Instrumentes geändert werden. In the figure sit an embodiment of the inventive concept shown. the illustration shows an inclination balance with two bells. The measuring weight SG is guided in a pipe connected to the balance beam, which runs through the axis of rotation goes through, while the cutting edge bearings are on both sides of this tube. The measuring range of the instrument can be changed by moving the measuring weight will.

Das Meßgewicht SG ist an einem biegsamen Glied LS aufgehängt. In der Drehachse des Waagebalkens geht LS durch eine feine oifnung hindurch. Bei Bewegung der Waage wird die Entfernung des Gewichtes SG von der Drehachse nicht geändert. LS ist in eine Schraubspindel GS eingehängt. die mitteils Drehung einer Mutter in der Längsrichstufig verschoben wird und gegen Verdrehen gesichert ist. Mittels dieser Einrichtung ist es möglich, jederzeit im Betrieb eine Rnderung des Mehbereiches vornehmen zu können, ohne einen beweglichen Teil des Gerätes zu berühren.The measuring weight SG is suspended from a flexible link LS. In the The LS axis of rotation of the balance beam goes through a fine opening. When moving the balance does not change the distance of the weight SG from the axis of rotation. LS is suspended in a screw spindle GS. the communicative rotation of a nut in the longitudinal direction is shifted and is secured against twisting. By means of this It is possible to set up a change in the excess range at any time during operation to be able to do without touching a moving part of the device.

Bringt man bei dieser Einrichtung das Meßgewicht mit seinem Schwerpunkt bis in die Drehachse. so kann leicht und bequem die Indifferenz des Gerätes geprüft werden. If you bring the measuring weight with its center of gravity with this device up to the axis of rotation. in this way, the indifference of the device can be checked easily and conveniently will.
