Abstract
Um bei einer Vorrichtung zur Druckmessung, insbesondere zur Hochdruckmessung, mit einem in einem Sensorgehäuse angeordneten Druckaufnehmer, wobei das Sensorgehäuse ein mit einem Druckanschlussstutzen versehenes erstes Sensorgehäuseteil und ein mit einem elektrischen Anschluss versehenes zweites Sensorgehäuseteil aufweist, den Fertigungsaufwand zu verringern, wird vorgeschlagen, dass das zweite Sensorgehäuseteil mittels eines zwischen dem ersten Sensorgehäuseteil und dem zweiten Sensorgehäuseteil angeordneten Verbindungsteils an dem ersten Sensorgehäuseteil befestigt ist, welches Verbindungsteil beispielsweise als einfaches Stanzbiegeteil oder dünnwandiges Rohrteil gefertigt werden kann.In order to reduce the manufacturing effort in a device for pressure measurement, in particular for high pressure measurement, with a pressure sensor arranged in a sensor housing, the sensor housing having a first sensor housing part provided with a pressure connection piece and a second sensor housing part provided with an electrical connection, it is proposed that this second sensor housing part is fastened to the first sensor housing part by means of a connecting part arranged between the first sensor housing part and the second sensor housing part, which connecting part can be manufactured, for example, as a simple stamped and bent part or thin-walled tubular part.
Description
Die Erfindung betrifft eine Vorrichtung zur Druckmessung mit den Merkmalen des Oberbegriffs des unabhängigen Anspruchs 1.The invention relates to a device for pressure measurement with the features of the preamble of the independent claim 1.
Eine derartige Vorrichtung zur Druckmessung,
die beispielsweise aus der
Die erfindungsgemäße Vorrichtung zur Druckmessung mit den kennzeichnenden Merkmalen des Anspruchs 1 ist gegenüber dem bekannten Stand der Technik preiswerter und einfacher herstellbar. Vorteilhaft kann das erste Sensorgehäuseteil als plattenförmiges Basisteil in sehr einfacher Weise gefertigt werden, ohne dass eine Nut oder Bördelkante an dem ersten Sensorgehäuseteil vorgesehen werden muss. Zur Verbindung des ersten Sensorgehäuseteils und des zweiten Sensorgehäuseteils ist ein zwischen den beiden Sensorgehäuseteilen angeordnetes zusätzliches Verbindungsteil vorgesehen, dass preisgünstig beispielsweise aus einem Metallblech oder dünnwandigen Metallrohr hergestellt werden kann. Durch das Verbindungsteil wird der Fertigungsaufwand zur Herstellung des ersten Sensorgehäuseteils stark reduziert. Da in das erste Sensorgehäuseteil keine Nut eingebracht wird und keine Bördelkante daran angeordnet ist, kann dieses dünner ausgebildet werden, wodurch Materialkosten eingespart werden. Insbesondere kann das erste Sensorgehäuseteil als einfaches Stanzteil gefertigt werden.The device for pressure measurement according to the invention with the characterizing features of claim 1 is compared to known prior art cheaper and easier to manufacture. The first sensor housing part can advantageously be a plate-shaped base part can be manufactured in a very simple manner without a groove or Flanged edge the first part of the sensor housing must be provided. For connecting the first part of the sensor housing and the second sensor housing part is an additional one arranged between the two sensor housing parts Connection part provided that inexpensive, for example, from one Sheet metal or thin-walled Metal pipe can be made. Through the connecting part the manufacturing effort for the production of the first sensor housing part greatly reduced. Since no groove was made in the first sensor housing part and no flanged edge on it is arranged, this can be thinner are trained, thereby saving material costs. In particular can the first sensor housing part can be manufactured as a simple stamped part.
Vorteilhafte Ausführungsbeispiele und Weiterentwicklungen der Erfindung werden durch die in den abhängigen Ansprüchen angegebenen Merkmale ermöglicht.Advantageous exemplary embodiments and further developments the invention are defined by those in the dependent claims Features.
Besonders preiswert kann das Verbindungsteil als einfaches Stanzbiegeteil oder aus einem dünnwandigen Rohr gefertigt werden.The connecting part can be particularly inexpensive can be manufactured as a simple stamped and bent part or from a thin-walled tube.
Zur Befestigung des ersten Sensorgehäuseteils an dem zweiten Sensorgehäuseteil ist vorgesehen, dass ein umlaufender, vorzugsweise kreisringförmiger Abschnitt des Verbindungsteils mit einer Fläche des ersten Sensorgehäuseteils verschweißt wird.For fastening the first part of the sensor housing on the second sensor housing part it is provided that a circumferential, preferably annular section of the connecting part with a surface of the first sensor housing part is welded.
Das Verbindungsteil kann in einem Ausführungsbeispiel mittels einer Bördelung an dem zweiten Sensorgehäuseteil festgelegt werden. Zusätzlich ist am Verbindungsteil eine umlaufende Nut ausgebildet, in welche die Stirnseite einer umlaufenden Gehäusewand des zweiten Sensorgehäuseteils eingreift.The connecting part can be in one embodiment by means of a crimp on the second sensor housing part be determined. In addition is formed a circumferential groove on the connecting part, in which the Front of a surrounding housing wall of the second sensor housing part intervenes.
Falls das zweite Sensorgehäuseteil aus Kunststoff gefertigt ist, kann das Verbindungsteil auch mit einem Abschnitt in den Kunststoff des zweiten Sensorgehäuseteils eingebettet sein und mit einem zur Verbindung mit dem ersten Sensorgehäuseteil vorgesehenen weiteren Abschnitt davon abstehen. Bei diesem Ausführungsbeispiel kann das zweite Sensorgehäuseteil beispielsweise als preiswertes Spritzgussteil gefertigt werden, wobei das Verbindungsteil als Einlegeteil in das Spritzgusswerkzeug eingesetzt wird.If the second sensor housing part is made of plastic, the connector can also a section in the plastic of the second sensor housing part be embedded and with one for connection to the first sensor housing part stand out from the intended further section. In this embodiment can the second sensor housing part for example manufactured as an inexpensive injection molded part, the connecting part being used as an insert in the injection molding tool becomes.
