Description

Werkstoffprüfmaschine mit Kraftmessung durch Neigungspendel und Meßbereichkennzeidinung Werkstoffprüfmaschinen werden neben Kraftmessung durch Manometer, Waagen, meist jedoch mit Neigungspendel ausgerüstet. Dabei erhält das Neigungspendel fast immer mehrere Meßbereiche, die auf einer Skalenscheibe zum Ablesen der jeweiligen Belastung aufgetragen sind. Das Neigungspendel selbst erhält den Meßbereichen entsprechend verschiedene aufsetzbare oder aufschiebbare Gewichte. Beispielsweise wird eine 40 t Universalprüfmaschine mit Neigungspendel, wie man sie in allen Laboratorien, Forschungsinstituten und Werksabnahmestellen findet, mit drei Meßbereichen ausgestattet, von 40 t, 20 t und 4 t. Nun kommt es vor, daß Verwechselungen beim Aufsetzen der Gewichte für den entsprechenden Meßbereich eintreten und dadurch die Ablesungen an den Skalen falsch sind. Durch die Erfindung sollen diese Fehlablesungen ausgeschaltet werden. Zu diesem Zweck sind am Neigungspendel Kontakte vorgesehen, die derart angeordnet sind, daß beim Aufsetzen eines Belastungsgewichtes am Bedienungsstand der Meßbereich, der durch das Aufsetzen des Belastungsgewichtes eingeschaltet ist, kenntlich wird. Das kann beispielsweise dadurch geschehen, daß die zum aufgesetzten Belastungsgewicht gehörende Skala beim Aufsetzen des Belastungsgewichtes beleuchtet wird. Die nicht eingeschalteten Meßbereiche bzw. Skalen bleiben unbeleuchtet, oder aber man kann die Skalen in mehreren Farben ausführen und durch die Kontakte Signallampen schalten, die in der Farbe der Skala aufleuchten.Materials testing machine with force measurement by inclination pendulum and measuring range identification Material testing machines are measured in addition to force using pressure gauges, scales, but mostly with an inclination pendulum equipped. The inclination pendulum almost always receives several measuring ranges, the are plotted on a dial to read off the respective load. That The inclination pendulum itself has various attachable elements depending on the measuring range or sliding weights. For example, a 40 t universal testing machine is used with inclination pendulum, as found in all laboratories, research institutes and There are factory acceptance points, equipped with three measuring ranges, from 40 t, 20 t and 4 t. Now it happens that mix-ups when putting on the weights for the corresponding Enter the measuring range and the readings on the scales are incorrect. By the invention aims to eliminate these misreadings. To this end contacts are provided on the inclination pendulum, which are arranged such that the Put on a load weight at the control station of the measuring range, which by the placing of the loading weight is switched on, is recognizable. That can happen, for example, that the weight belonging to the attached loading weight The scale is illuminated when the weight is put on. The ones not switched on Measuring areas or scales remain unlit, or the scales can be divided into several Execute colors and switch signal lamps that are in the color through the contacts light up on the scale.
