Messgerät für die Automatisierungstechnik mit einerMeasuring instrument for automation technology with a
Einhandbedienunghand operation
[0001] Die Erfindung betrifft ein Messgerät für die Automatisierungstechnik mit einer Einhandbedienung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a measuring device for automation technology with a one-handed operation according to the preamble of claim 1.
[0002] In der Automatisierungstechnik werden vielfach Messgeräte eingesetzt, die zurIn automation often measuring devices are used, the
Erfassung der Prozess variablen Druck, Temperatur, Durchfluss, pH- Wert, etc. dienen. Eine Vielzahl derartiger Messgeräte wird von der Firmengruppe Endress+Hauser hergestellt und vertrieben.Capture the process variable pressure, temperature, flow, pH, etc. are used. A large number of such measuring devices is manufactured and distributed by the Endress + Hauser group of companies.
[0003] Herkömmliche Messgeräte für die Automatisierungstechnik mit einerConventional measuring devices for automation technology with a
Einhandbedienung bestehen in der Regel aus einem Elektronikgehäuse, dessen Innenraum mit einem Deckel verschließbar ist. In diesem Deckel ist meist ein Abdeckglas integriert, das die Sicht auf eine hinter dem Abdeckglas liegenden Anzeige-ZBedieneinheit freigibt. Um die Geräteelektronik zu schützen, verschließt der Deckel den Innenraum des Gehäuses dicht, so, dass Schmutz bzw. Wasser nicht in den Innenraum eindringen können.One-handed operation usually consist of an electronics housing whose interior is closable with a lid. In this cover, a cover glass is usually integrated, which releases the view of a lying behind the cover glass display ZBedieneinheit. In order to protect the device electronics, the cover tightly seals the interior of the housing, so that dirt or water can not penetrate into the interior.
[0004] Die Anzeige-ZBedieneinheit umfasst mehrere Tastenfelder, die durch das Abdeckglas hindurch aktiviert werden könnenThe display ZBedieneinheit comprises a plurality of keypads, which can be activated through the cover glass
[0005] Neben solchen Tastenfeldern sind auch noch zur Bedienung von Messgeräten so genannte Drehdrückschalter bekannt. Durch Drehen des Drehdrückschalters kann der Inhalt einer Anzeige (z. B. LC-Display) geändert bzw. ausgewählt werden. Problematisch bei solchen Drehdrückschaltern ist jedoch, dass sie sehr aufwendig aufgebaut sind, um eine in der Automatisierungstechnik typische Dichtigkeit zu gewährleisten. Außerdem nehmen sie sehr viel Platz in Anspruch weshalb sie bei kleineren Geräten i.d.R. nicht eingesetzt werden.In addition to such keypads so-called rotary pushbutton switch are also known for the operation of measuring devices. By turning the rotary pushbutton, the content of a display (eg LC display) can be changed or selected. The problem with such rotary push-buttons, however, is that they are constructed very expensive in order to ensure a typical in automation technology tightness. In addition, they take up a lot of space which is why they are used on smaller devices i.d.R. not be used.
[0006] Sowohl Drehdrückschalter, wie auch Tastenfelder erlauben keine Bedienung mit Schutzhandschuhen, wie sie z. B. im Petrobereich verwendet werden. Fehlt ein Drehdrückschalter so muss der Bediener auf dessen Vorteile, z.B. einer besonders zügigen Bedienbarkeit verzichten.Both rotary pushbutton, as well as keypads do not allow operation with protective gloves, such as z. B. used in the petrochemical sector. If a rotary pushbutton is missing, the operator must be aware of its advantages, e.g. dispense with a particularly rapid operability.
[0007] Aufgabe der Erfindung ist es deshalb, ein Messgerät für die Automatisierungstechnik mit einer Einhandbedienung zu schaffen, das die oben genannten Nachteile nicht aufweist, das insbesondere einen möglichst guten Schutz für die Geräteelektronik gewährleistet und das darüber hinaus auch eine Bedienung mit Schutzhandschuhen ermöglicht. [0008] Gelöst wird diese Aufgabe durch die in Anspruch 1 angegebenen Merkmale.The object of the invention is therefore to provide a measuring device for automation technology with a one-hand operation, which does not have the disadvantages mentioned above, which ensures in particular the best possible protection for the device electronics and also allows operation with protective gloves. This object is achieved by the features specified in claim 1.

Das Messgerät 1 besteht im Wesentlichen aus einem Gehäuse 2, das zur Aufnahme einer Geräteelektronik 8 dient. Die Geräteelektronik 8 umfasst eine Anzeige-ZBedieneinheit 10 mit drei Tastenfelder Tl, T2, T3 zur Eingabe und einem LC-Display zur Anzeige.In Fig. 1, a conventional measuring device for automation technology is shown. The measuring device 1 consists essentially of a housing 2, which serves to receive a device electronics 8. The device electronics 8 comprises a display ZBedieneinheit 10 with three keypads Tl, T2, T3 for input and a LC display display.
[0019] Der Innenraum 4 des Gehäuses 2 ist mit einem Deckel 6 verschlossen. Damit dasThe interior 4 of the housing 2 is closed by a cover 6. So that
LC-Display und die Tastenfelder Tl, T2, T3 von außen sichtbar sind, weist der Deckel 6 ein entsprechendes Fenster 12 auf. Er ist fest mit dem Gehäuse 2 verschraubt. Zur Energieversorgung des Messgeräts 1 dient ein Hilfsenergieanschluss 7. Das vom Messgerät erfasste Messsignal kann über einen Signalanschluss 9 zum Beispiel an eine Warte weitergeleitet werden.LC display and the keypads Tl, T2, T3 are visible from the outside, the lid 6 has a corresponding window 12. He is firmly bolted to the housing 2. An auxiliary power connection 7 serves to supply power to the measuring device 1. The measuring signal detected by the measuring device can be forwarded to a control room via a signal connection 9, for example.
[0020] In Fig. 2 ist der Deckelbereich eines erfindungsgemäßen Messgeräts näher dargestellt. Entsprechende Teile in Fig. 2 weisen dieselbe Bezifferung wie in Fig. 1 auf.In Fig. 2, the lid portion of a measuring device according to the invention is shown in more detail. Corresponding parts in Fig. 2 have the same numbering as in Fig. 1.
[0021] Der Deckel 6 ist hierbei zweiteilig ausgeführt. Er besteht aus einemThe cover 6 is in this case made in two parts. It consists of one
Deckelgrundkörper 16 und einem Ringelement 14. Das Ringelement 14 stützt sich elastisch über ein Federelement 30 am Deckelgrundkörper 16 ab.Lid body 16 and a ring member 14. The ring member 14 is elastically supported by a spring member 30 on the lid body 16.
[0022] Das Ringelement 14 ist um die Längsachse L drehbar gelagert. Es kann zusätzlich noch parallel zur Längsachse geringfügig verschoben werden.The ring member 14 is rotatably supported about the longitudinal axis L. It may additionally are still slightly shifted parallel to the longitudinal axis.
[0023] Weiterhin ist in Fig. 2 das Gewinde 18 dargestellt, über das der Deckelgrundkörper 16 mit dem Gehäuse 2 verschraubt ist. Entsprechende Dichtungselemente sind jedoch nicht dargestellt.Furthermore, in Fig. 2, the thread 18 is shown, via which the lid base body 16 is screwed to the housing 2. However, corresponding sealing elements are not shown.
[0024] Am Deckel 6 sind Sensoren 20 angeordnet, über die die Drehbewegung und die Hubbewegung des Ringelements 16 erfasst werden können. Entsprechende Verbindungsleitungen zur Geräteelektronik 8 sind der Übersichtlichkeit halber nicht näher dargestellt.On the cover 6 sensors 20 are arranged, via which the rotational movement and the lifting movement of the ring member 16 can be detected. Corresponding connection lines to the device electronics 8 are not shown in detail for the sake of clarity.
[0025] Durch verstärktes Drücken des Ringelements 14 in Richtung des Gehäuses 2 gelangen entsprechende Kontaktflächen 40a bzw. 40b zur Anlage. Die Ausgestaltung der Kontaktflächen 40a und 40b ist so, dass diese eine Kraftübertragung zwischen Ringelement 14 und Deckelgrundkörper 16 ermöglichen. Dadurch kann der Deckel 6 über das Ringelement 14 gedreht werden. So kann z. B. der Deckel 6 vom Gehäuse 2 gelöst oder mit diesem fest verschraubt werden.By intensified pressing of the ring member 14 in the direction of the housing 2 corresponding contact surfaces reach 40a and 40b to the plant. The configuration of the contact surfaces 40a and 40b is such that they enable a force transmission between the ring element 14 and the lid base 16. As a result, the cover 6 can be rotated via the ring element 14. So z. B. the lid 6 detached from the housing 2 or screwed firmly with this.
[0026] Hinter einem Abdeckglas 12a ist eine Anzeigeeinheit 10a vorgesehen.Behind a cover glass 12a, a display unit 10a is provided.
[0027] Nachfolgend ist die Funktionsweise der Erfindung näher erläutert. Durch Drehen des Ringelements 14 kann der Inhalt des LC-Displays LCD entsprechend einer vorgesehenen Menüauswahl geändert werden. So kann zum Beispiel die Einheit, mit der ein Messwert im LC-Display dargestellt werden soll, verändert werden. Bestätigt wird die Auswahl der Einheit durch Drücken, verworfen wird die Einheit durch Ziehen des Ringelements 14.The operation of the invention is explained in more detail below. By rotating the ring member 14, the content of the LC display LCD can be changed according to an intended menu selection. For example, the unit with which a measured value is to be displayed in the LC display can be changed. The selection of the unit is confirmed by pressing, the unit is rejected by pulling the ring element 14.
[0028] In Fig. 3 ist eine Aufsicht auf ein erfindungsgemäßes Messgerät 1 dargestellt. Über das Ringelement 14 kann, wie dargestellt, die dritte Kommastelle des angezeigten Werts 0,942 geändert werden. In einfacher Weise bedeutet eine Linksdrehung „hoch oder minus", ein Rechtsdrehen „runter oder plus", ein Drücken „enter oder ja, Auswahl hinein oder aufklappen", ein Ziehen „escape oder nein, Abbrechen zurück oder schließen".In Fig. 3 is a plan view of an inventive measuring device 1 is shown. As shown, the third decimal point of the displayed value 0.942 can be changed via the ring element 14. In a simple way, a left turn means "up or down", a right turn "down or plus", a press "enter or yes, select in or open", a pull "escape or no, cancel back or close".
[0029] In Fig. 3 ist zusätzlich noch grob angedeutet, wie die Einhandbedienung erfolgt wenn das Gehäuse die Größe einer Hand nicht wesentlich übersteigt. Bei noch größeren Gehäusen wird das Ringelement an der Seite angefasst.In Fig. 3 is also roughly indicated how the one-hand operation occurs when the housing does not significantly exceed the size of a hand. For even larger housings, the ring element on the side is touched.
[0030] In vorteilhafter Weise sind die Sensoren 20 als Hall-Sensoren oder optische Sensoren ausgebildet.Advantageously, the sensors 20 are designed as Hall sensors or optical sensors.
[0031] In vorteilhafter Weise sind Ringelement 14 und Deckel 6 über die Kontaktflächen 40a, 40b reibschlüssig koppelbar, um so ein einfaches Lösen bzw. Verschrauben des Deckels 6 zu ermöglichen. [0032] Mit Hilfe des erfindungsgemäßen Messgeräts für die Prozessautomatisierungstechnik ist auch eine Einhandbedienung mit teilweise recht klobigen Schutzhandschuhen möglich. Das Ringelement 14 weist hierfür einen Durchmesser von ca. 10 cm auf. Durch eine entsprechende Riffelung am Rand des Ringelements 14 kann dieses auch mit klobigen Schutzhandschuhen einfach und zuverlässig gedreht, gedrückt oder gezogen werden. Ein weiterer Vorteil, den die Erfindung bietet, ist das keine mechanischen Durchführungen in den Innenraum 4 des Messgeräts führen. Dadurch kann das Messgerät entsprechend der gewünschten Dichtheit ausgeführt werden.Advantageously, ring member 14 and cover 6 via the contact surfaces 40a, 40b are frictionally coupled, so as to allow a simple loosening or screwing the lid 6. With the help of the measuring device according to the invention for process automation technology and a one-handed operation with sometimes quite clunky protective gloves is possible.
