Abstract
(DE)
Die Erfindung betrifft eine Sensoreinheit (1) sowie eine Hydraulik- oder Pneumatiksystem mit solch einer Sensoreinheit (1), wobei Letztere einen Drucksensor (7) zur Ermittlung einer Druckänderung eines Fluids aufweist. Der Drucksensor (7) weist einen Druckmessumformer auf, der über seinen Druckkanal (25) mit dem Fluid verbindbar ist. Um neben dem Druck eine weitere Kenngröße des Systems zu ermitteln, welche den momentanen Zustand des Systems beschreibt und zur Verbesserung der Leistungsfähigkeit und Sicherheit des Systems beizutragen, umfasst die Sensoreinheit (1) ergänzend zum Mainboard (3) auf welchem zumindest der Drucksensor (7) angeordnet ist, einen Positionssensor (15) zur berührungslosen Erfassung einer Lage- und Positionsänderung einer externen, nicht der Sensoreinheit (1) zugehörigen, Komponente. Der Positionssensor (15) ist am Mainboard (3) oder auf einem weiteren Board (13) angeordnet und ist zur Erfassung einer Lage- und Positionsänderung auf die externe Komponente ausrichtbar. Die Sensoreinheit (1) umfasst weiter elektronische Bauelemente (20) zum Betreiben und zum Generieren von Ausgangssignalen des Drucksensors (7) und des Positionssensors (15) sowie elektrische Anschlüsse (19).
(EN)
The invention relates to a sensor unit (1) and a hydraulic or pneumatic system having such a sensor unit (1), wherein the latter has a pressure sensor (7) for determining a pressure change in a fluid. The pressure sensor (7) has a pressure transducer, which is connectable to the fluid via the pressure channel (25) thereof. In order to determine an additional parameter of the system, in addition to the pressure, which additional parameter describes the current state of the system, and to contribute to improving the performance and safety of the system, the sensor unit (1) additionally comprises, in addition to the mainboard (3) on which at least the pressure sensor (7) is arranged, a position sensor (15) for contactless detection of a location and position change of an external component which is not associated with the sensor unit (1). The position sensor (15) is arranged on the mainboard (3) or on an additional board (13) and can be oriented towards the external component in order to detect a location and position change. The sensor unit (1) comprises additional electronic components (20) for operating and generating output signals of the pressure sensor (7) and of the position sensor (15) and electrical connections (19).

L'invention concerne une unité de détection (1) et un système hydraulique ou pneumatique comportant une telle unité de détection (1), cette dernière comprenant un capteur de pression (7) pour déterminer une variation de pression d'un fluide. Le capteur de pression (7) comprend un transducteur de pression qui peut être relié au fluide par le biais de son canal de pression (25). Pour déterminer en plus de la pression une autre grandeur caractéristique du système, qui décrit l'état momentané du système, et pour contribuer à l'amélioration de la performance et de la sécurité du système, l'unité de détection (1) comprend, pour compléter le panneau principal (3) sur lequel est disposé au moins le capteur de pression (7), un capteur de position (15) pour la détection sans contact d'une variation d'emplacement et de position d'un composant externe, ne faisant pas partie de l'unité de détection (1). Le capteur de position (15) est disposé sur le panneau principal (3) ou sur un autre panneau (13) et est orientable en direction du composant externe pour la détection d'une variation d'emplacement ou de position. L'unité de détection (1) comprend en outre des composants électroniques (20) pour l'exploitation et la génération de signaux de sortie du capteur de pression (7) et du capteur de position (15) et des connexions électriques (19).
