Abstract
Description
Die vorliegende Erfindung betrifft ein Potentiometer.The The present invention relates to a potentiometer.
Potentiometer sind allgemein bekannt und umfassen beispielsweise ein Trägerelement, das eine Potentiometer-Schaltung mit einer Widerstandsbahn und einer Kollektorbahn aufweist. Ferner ist üblicherweise ein Schleiferträger vorgesehen, der einen die Widerstandsbahn mit der Kollektorbahn elektrisch verbindenden Schleifer aufweist und der relativ zum Trägerelement verstellbar ist. Durch Betätigen des Schleiferträgers über ein entsprechendes Betätigungsglied wird die Position, in welcher der Schleifer die Widerstandsbahn mit der Kollektorbahn verbindet, variiert, wodurch das Potentiometer ein mit der aktuellen Position korreliertes Signal generiert. Potentiometer können beispielsweise als Positionssensoren verwendet werden.potentiometer are well known and include, for example, a support element, a potentiometer circuit with a resistor track and a Collector track has. Furthermore, a slider carrier is usually provided, the one electrically connecting the resistor track to the collector track Has grinder and which is adjustable relative to the support element. By pressing the Grinder carrier over corresponding actuator becomes the position in which the slider the resistance path connects with the collector track, varying, causing the potentiometer generates a signal correlated with the current position. potentiometer can For example, be used as position sensors.
Bei sicherheitsrelevanten Anwendungen ist es erwünscht, das Potentiometer redundant auszugestalten. Hierzu ist es grundsätzlich möglich, zwei Potentiometer-Schaltungen parallel anzuordnen, die gleichzeitig mit zwei Schleifern zusammen wirken. Hierzu ist jedoch ein relativ großer Bauraum erforderlich.at For safety-related applications, it is desirable that the potentiometer be redundant embody. For this it is possible in principle, two potentiometer circuits to arrange parallel, which act simultaneously with two grinders together. For this However, it is a relatively large one Space required.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für ein Potentiometer eine verbesserte Ausführungsform anzugeben, die sich insbesondere durch eine kompakte Bauweise in Verbindung mit einer Redundanz auszeichnet.The present invention employs dealing with the problem, for a potentiometer to provide an improved embodiment, the in particular by a compact design in conjunction with a Redundancy distinguishes.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively the subject of the independent Claim solved. Advantageous embodiments are the subject of the dependent Claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, ein Potentiometer mit einem Hall-Sensor redundant zu kombinieren. Ein Hall-Sensor baut vergleichsweise kompakt und lässt sich dadurch insbesondere in ein konventionelles Potentiometer integrieren und mit diesem redundant betreiben. Das so gebildete Potentiometer mit integriertem Hall-Sensor kann somit zum einen Signale des Potentiometers und parallel dazu Signale des Hall-Sensors generieren, die sich redundant verwenden lassen. Der integrale Aufbau ist extrem kompakt. Ferner lassen sich durch eine entsprechende Programmierung des Hall-Sensors bzw. eines mit dem Hall-Sensor ausgestatteten integrierten Schaltkreises zusätzliche Funktionalitäten in das so gebildete Potentiometer integrieren.The The present invention is based on the general idea of a potentiometer to be redundantly combined with a Hall sensor. A Hall sensor builds comparatively compact and can be characterized in particular integrate into a conventional potentiometer and with this operate redundantly. The thus formed potentiometer with integrated Hall sensor can thus on the one hand signals of the potentiometer and in parallel signals of the Generate Hall sensors that can be used redundantly. Of the integral construction is extremely compact. Furthermore, can be by a appropriate programming of the Hall sensor or one with the Hall sensor equipped integrated circuit additional functionalities integrate into the thus formed potentiometer.
Entsprechend einer vorteilhaften Ausführungsform kann zur Realisierung des Hall-Sensors ein Dauermagnet vorgesehen sein, der in herkömmlicher Weise mit einem Hall- Sensorelement zusammenwirkt. Dabei kann der Dauermagnet bei einem konventionell aufgebauten Potentiometer am Schleiferträger angeordnet sein und zusammen mit diesem relativ zum Trägerelement verstellbar sein. Gleichzeitig kann das Hall-Sensorelement am Trägerelement angeordnet sein. Durch Betätigen des Schleiferträgers wird somit einerseits der Schleifer relativ zur Potentiometer-Schaltung verstellt, während andererseits auch der Dauermagnet relativ zum Hall-Sensorelement verstellt wird. Der in das Potentiometer integrierte Hall-Sensor nutzt somit die für das Potentiometer ohnehin vorgesehene Betätigungseinrichtung, nämlich den Schleiferträger, was die Kompaktheit der integralen Bauweise unterstützt.Corresponding an advantageous embodiment can be provided to realize the Hall sensor, a permanent magnet be that in conventional Way with a Hall sensor element interacts. In this case, the permanent magnet in a conventional constructed potentiometer be arranged on the slider carrier and together with this relative to the carrier element be adjustable. At the same time, the Hall sensor element can be arranged on the carrier element. By pressing of the slider carrier Thus, on the one hand, the grinder becomes relative to the potentiometer circuit pretended while on the other hand, the permanent magnet is adjusted relative to the Hall sensor element becomes. The integrated into the potentiometer Hall sensor thus uses the for the potentiometer anyway provided actuator, namely the Grinder carriers which supports the compactness of the integral construction.
Während bei konventionellen Hall-Sensoren das Hall-Sensorelement am jeweiligen Träger an einer dem Dauermagneten zugewandten Seite angeordnet ist, kann gemäß einer vorteilhaften Ausführungsform beim erfindungsgemäßen Potentiometer vorgesehen sein, die Potentiometer-Schaltung und das Hall-Sensorelement an voneinander abgewandten Seiten des Trägerelements anzuordnen. Dies hat zur Folge, dass sich beim erfindungsgemäßen Potentiometer das Hall-Sensorelement an einer vom Dauermagneten abgewandten Seite des Trägerelements befindet, so dass die Betätigung des Hall-Sensorelements mit dem Dauermagneten durch das jeweilige Trägerelement hindurch erfolgt. Durch diese Bauweise kann am Trägerelement die bislang weitgehend ungenutzte, vom Schleifer abgewandete Seite zur Anordnung des Hall-Sensorelements genutzt werden, was ebenfalls zur kompakten Bauweise des integrierten Potentiometers beiträgt.While at Conventional Hall sensors, the Hall sensor element on the respective carrier on a The permanent magnet facing side is arranged, can according to a advantageous embodiment provided in the potentiometer according to the invention be, the potentiometer circuit and the Hall sensor element on Arrange facing away from each other sides of the support element. This As a result, the Hall sensor element in the potentiometer according to the invention on a side facing away from the permanent magnet side of the support element so that the actuation of the Hall sensor element takes place with the permanent magnet through the respective carrier element. By this construction can on the support element the previously largely unused, remote from the slider side used for the arrangement of the Hall sensor element, which also contributes to the compact design of the integrated potentiometer.
