Claims (5)

1. Messvorrichtung zur elektrischen Erkennung der Anwesenheit fließfähiger Medien, unabhängig von deren elektrischen Leitfähigkeit, dadurch gekennzeichnet, dass die Überwachung der Anwesenheit nicht mit einem mechanisch bewegten Messwertgeber, einer kapazitiven Auswertung oder konduktiv arbeitenden Vorrichtungen, sondern mit Ultraschall erfolgt, wobei der Ultraschallgeber in einen Körper eingebaut ist, der bei allen Anwendungen in der Lebensmittel- und pharmazeutischen Industrie unbedenklich ist.1.Measuring device for the electrical detection of the presence of flowable media, regardless of their electrical conductivity, characterized in that the presence is not monitored with a mechanically moving sensor, a capacitive evaluation or a conductive device, but with ultrasound, the ultrasound transmitter being in one Body is built in, which is harmless for all applications in the food and pharmaceutical industries. 2. Messvorrichtung zur elektrischen Erkennung der Anwesenheit fließfähiger Medien, unabhängig von deren elektrischen Leitfähigkeit nach Schutzanspruch 1, gekennzeichnet dadurch, dass der Messwertgeber aus einem Stab besteht, der in das Medium hineinragt. Dieser Stab kann kundenseitig gekürzt werden, ohne dass die Funktion beeinträchtigt wird. Die Anwesenheitsmeldung erfolgt dann, wenn das Medium die Spitze dieses Stabes berührt. Somit kann der Kunde nachträglich die Höhe des Mediums, bei der die Anwesenheitsmeldung erfolgen soll, festlegen.2. Measuring device for electrical detection of the presence of flowable media, independently their electrical conductivity according to protection claim 1, characterized by that the sensor consists of a rod that protrudes into the medium. This staff can shortened by the customer without impairing the function. The Presence is reported when the medium touches the tip of this rod. Consequently the customer can subsequently change the amount of the medium at which the presence is reported should determine. 3. Messvorrichtung zur elektrischen Erkennung der Anwesenheit fließfähiger Medien, unabhängig von deren elektrischen Leitfähigkeit nach Schutzanspruch 1, gekennzeichnet dadurch, dass die Auswertung auf der Basis einer Änderung der Gestalt des Echos oder auch der Bedämpfung des Ultraschall-Sendeimpulses erfolgt. Hierbei ist weder eine Einstellung der Empfindlichkeit notwendig noch ist ein Abgleich auf das Füllgut erforderlich. 3. Measuring device for electrical detection of the presence of flowable media, independently their electrical conductivity according to protection claim 1, characterized by that the evaluation based on a change in the shape of the echo or the The ultrasonic transmission pulse is damped. Here is not an attitude of Sensitivity is still necessary and adjustment to the product is necessary.   4. Messvorrichtung zur elektrischen Erkennung der Anwesenheit fließfähiger Medien, unabhängig von deren elektrischen Leitfähigkeit nach Schutzanspruch 1, gekennzeichnet dadurch, dass die Ultraschall- Sende- und Empfängereinheit in einem Aufnahmekörper integriert ist, der gleichzeitig als Dichtkonus für eine elastische Dichtung mit einer Schneidkante dient. Daraus resultiert eine totraumfreie, spaltfreie Abdichtung des Sensors zum Prozess hin.4. Measuring device for electrical detection of the presence of flowable media, independently their electrical conductivity according to protection claim 1, characterized by that the ultrasound transmitter and receiver unit is integrated in a receiving body that also serves as a sealing cone for an elastic seal with a cutting edge. Out of it results in a gap-free, gap-free sealing of the sensor to the process. 5. Messvorrichtung zur elektrischen Erkennung der Anwesenheit fließfähiger Medien, unabhängig von deren elektrischen Leitfähigkeit nach Schutzanspruch 1, gekennzeichnet dadurch, dass über den Anschlag des Dichtkonus in der Einbaumuffe die Position einer seitlich an der Messvorrichtung angebrachten Kabelzuführung festgelegt werden kann.5. Measuring device for electrical detection of the presence of flowable media, independently their electrical conductivity according to protection claim 1, characterized by that the position of one on the side of the Measuring device attached cable feed can be determined.
