Abstract
(DE)
Druckmessaufnehmer zur hydrostatischen Füllstands- oder Pegelmessung, mit - einem an einem ersten Ende des Trägers (1) vorgesehenen, in eine Flüssigkeit (15) eintauchbaren Sensorgehäuse (3), und - einem Drucksensor (5), der derart in dem Sensorgehäuse (3) angeordnet ist, dass der Drucksensor (5) bei in die Flüssigkeit (15) eingetauchtem Sensorgehäuse (3) mit einem über die Flüssigkeit darauf ausgeübten Druck (p) beaufschlagt ist, dadurch gekennzeichnet, dass - der Drucksensor (5) im Inneren des Sensorgehäuses (3) in einem unmittelbar an eine in der vom Träger (1) abgewandten Stirnwand des Sensorgehäuses (3) vorgesehenen Öffnung (19) angrenzenden stirnseitigen Endbereich des Sensorgehäuses (3) angeordnet ist, und - am Sensorgehäuse (3) außenseitlich ein Gewindeprofil (21) vorgesehen ist, auf das eine als auswechselbare Komponente ausgebildete, Durchtrittsöffnungen (23) aufweisende, mit einem zu dem Gewindeprofil (21 ) komplementären Innengewinde (22) ausgestattete Schutzkappe (25) aufschraubbar ist oder aufgeschraubt ist.
(EN)
Pressure measuring sensor for hydrostatic filling level or level measurement, having - a sensor housing (3) which is provided at a first end of the carrier (1) and can be immersed in a liquid (15), and - a pressure sensor (5) which is arranged in the sensor housing (3) in such a manner that, when the sensor housing (3) is immersed in the liquid (15), a pressure (p) exerted thereon via the liquid is applied to the pressure sensor (5), characterized in that - the pressure sensor (5) is arranged in the interior of the sensor housing (3) in an end region of the sensor housing (3) at the end side that directly adjoins an opening (19) provided in that end wall of the sensor housing (3) which faces away from the carrier (1), and - a thread profile (21) is provided on the outside of the sensor housing (3), onto which thread profile a protective cap (25) which is in the form of a replaceable component, has passage openings (23) and is equipped with an internal thread (22) complementary to the threat profile (21) can be or has been screwed.

L'invention concerne un manomètre servant à mesurer de manière hydrostatique un niveau de remplissage ou un niveau. Le manomètre comprend : un boîtier (3) de capteur prévu sur une première extrémité du support (1), pouvant être plongé dans un liquide (15) ; et un capteur de pression (5), qui est disposé de telle manière dans le boîtier (3) de capteur que le capteur de pression (5) est soumis, lorsque le boîtier (3) de capteur est plongé dans le liquide (15), à l'action d'un pression (p) exercée sur celui-ci par l'intermédiaire du liquide. Le manomètre selon l'invention est caractérisé en ce que le capteur de pression (5) est disposé à l'intérieur du boîtier (3) de capteur dans une zone d'extrémité côté frontal, du boîtier (3) de capteur, jouxtant directement une ouverture (19) prévue sur une paroi frontale, opposée au support (1), du boîtier (3) de capteur, et un profil fileté (21) est prévu côté extérieur sur le boîtier (3) de capteur, sur lequel un capot de protection (25) réalisé sous la forme d'un composant remplaçable, comportant des ouvertures de passage (23), équipé d'un filetage intérieur (22) complémentaire par rapport au profil fileté (21) peut être vissé ou est vissé.
